  • Title:The Use of Wastewater in Livestock Production and its Socioeconomic and Welfare Implications
  • Time :

Abstract:

The use of wastewater for rearing domestic animals is a common phenomenon in most of the developing countries like Pakistan that face a serious shortage of freshwater resources. However, most of the literature has only focused on the indirect effects of wastewater use on animal health or productivity, and literature on the direct effects of wastewater use is rare. Therefore, this study aims to investigate the direct and indirect effects of wastewater usage on the prevalence of animal diseases and animal health in Pakistan. The study is based on a household-level survey of 360 domestic water buffalo herds collected from 12 districts of Punjab Province, Pakistan. We tested the prevalence of the animal’s diseases, animal’s health, and wastewater-use preference with various econometrics tools, such as the Poisson, negative binomial, and logistic regressions. The findings of the study show that the majority of the farmers use wastewater for buffalo bathing due to the shortage of freshwater resources. Results explore the prevalence of diseases such as clinical mastitis, tick infestation, and foot and mouth disease at the farm level significantly associated with buffalo bathing in the wastewater. Moreover, bathing in wastewater pre- and post-milking also plays a role in the occurrence of diseases. Particularly, if the buffalo’s access to wastewater for bathing is within 60 minutes after milking, the probability of the animals being exposed to mastitis is higher. Furthermore, on investigation, a number of factors are found, such as the distance to the water source, power shortage, groundwater availability, and the education of farmers that influence farmers’ behavior of letting their animals take a bath in wastewater. Moreover, the use of different preventive measures improves the animal health

  • Title:Involvement of Neutrophils in Exercise-Induced Muscle Damage and its Prevention
  • Time :

Abstract:

Neutrophils not only play a critical role in host defense by migrating to the site of infection and producing reactive oxygen species (ROS), but also mediate pathological processes involved in tissue destruction. Therefore, it is important to assess and modulate neutrophil activities. Exhaustive exercise facilitates neutrophil activity, suggesting their involvement with muscle damage [1-4]. However, at that time, we needed to separate neutrophils from whole blood, and great care was needed to do this. Also, it took at least 1 h to adjust a fixed cell concentration of neutrophils for the functional analyses, and some researchers criticized the method, saying that the recovery rate was low and the neutrophil functions were altered from the in vivo environments. Because we observed complex phenomena centered on neutrophils following exercise, some novel technology was required to examine the neutrophil dynamics and functional modulation. Thus, I would like to share some of our research on neutrophils in relation with exercise and muscle damage. I will begin with my early studies on neutrophil functional analyses and a newly developed measurement system [5-7]. Then, some key data about effects of exercise, antioxidant modulation, mechanisms of exercise-induced muscle damage, and possible preventive countermeasures such as functional foods targeting pathogenesis will be described [7-10].

  • Title:Hypoglycemic and Anti-Insulin Resistant Effects of Saskatoon Berry and its Active Components in Western Diet-Induced Obese and Insulin Resistance Mice and Relationship with Gut Microbiota
  • Time :

Abstract:

Diabetes becomes epidemic in worldwide countries. Nine out of ten diabetic patients are type 2 diabetes (TED). TED is characterized by insulin resistance and obesity. Uncontrolled diabetes leads serious consequences including heart attack, stroke, chronic renal failure, blindness and low limb amputation. Diabetes often requires lifetime treatment. Most of hypoglycemic medications have side effects. Natural foods or pharmaceuticals with hypoglycemic potential are expected to provide a safer management for diabetic patients. Saskatoon berry is a traditional food of First Nations people in North America, and has abundant amounts of anthologists, including cyanide-3-glucose (C3G). Our previous studies demonstrated Saskatoon berry powder (Sp) attenuated oxidation stress and inflammation, but did not alter glucose metabolism in genetic db/db diabetic mice. We recently examined the effects of SBp and C3G on glucose metabolism, insulin resistance, vascular inflammation, and intestinal microbiol in diet-induced insulin resistant mice, a model for TED. Male C57 BL/6J mice were fed control diet, high fat-high sucrose (HFHS) diet, HFHS+5% SBp (HFHS+B) or HFHS+C3G in a dosage comparable to that in 5% SBp for 12-15 weeks. The composition of bacterial community in mouse stool was characterized using the Illumine sequencing of V4 region of 16S rRNA gene. HFHS diet increased body weight, fasting plasma glucose, cholesterol, triglycerides, insulin, homeostatic model assessment-insulin resistance, monocyte adhesion, tumor necrosis factor-α, plainsmen activator inhibitor-1, monocyte chemotactic protein-1, intracellular cell adhesion molecule-1, urokinase plainsmen activator and its receptor in plasma or aortae, but not body weights, compared to the control diet. HFHS+B or HFHS+C3G diet postponed the increase in body weight, suppressed HFHS diet-induced disorders in insulin resistance, hepatic stenosis and vascular inflammation. The ratio of Firmicutes/Bactericides in the HFHS group was higher than that in the control group (p<0.01), and that in the HFHS+B or HFHS+C3G group was lower than that in the HFHS group (p<0.05). The abundances of S24-7 family bacteria negatively correlated with all tested metabolic or inflammatory variables and body weights of mice. The results suggest that Saskatoon berry and its component, C3G, are able to reduce HFHS diet-induced hyperglycemia, insulin resistance and vascular inflammation in mice with T2D. The beneficial effects of SBp and C3G may result, at least in part, from their impact on gut microbiol.

  • Title:Preparation of Corn Stover Nanocellulose and Properties Characterization Using Transmission Electron Microscopy (TEM), Instron Mechanical Measurements, Rheometry, and Diffusing Wave Spectroscopy (DWS)
  • Time :

Abstract:

Agricultural waste corn stover has very little value but can be good renewable, biodegradable, and inexpensive source to produce value-added products such as cellulose and nanocellulose. Cellulose was extracted from corn stover by the processes of alkali treatment and delignification, resulting in a >93% purity. The particle size of the extracted cellulose was reduced by mechanical shearing through high pressure homogenization. When passing through a homogenizer thirty times, the cellulose nanofibril (CNF) can be obtained. The diameters of the CNF ranged between 5 – 50 nm, and the lengths were microns. The mechanical properties of the films, made by corn stover cellulose, with and without high pressure homogenization shearing were evaluated using an Instron instrument. The films made by cellulose without shearing exhibited weaker mechanical properties, while the CNF films exhibited stronger mechanical properties. The linear rheological properties of CNF suspensions were investigated using mechanical rheometry and results show solid-like viscoelastic behavior. The microrheology of corn stover CNF suspensions was investigated by the novel technique diffusion wave spectroscopy (DWS) and compared with mechanical rheometry measuremants. DWS microrheology measurements were in excellent agreement with the conventional mechanical rheological studies for corn stover CNF. By comparing the mean-square displacement (MSD) of the microbeads embedded in five concentrations of corn stover CNF, we found that the suspensions exhibited slight heterogeneity behavior at the lower concentration of 0.25%, while the material displayed a definite degree of heterogeneity at higher concentrations. The magnitude of high-frequency viscoelastic moduli (|G*(ω)|) for the corn stover CNF is proportional to the 3/4 power of the frequency (ω), which is the semi- flexible polymer behavior. The identified properties of the corn stover CNF will provide us the useful information for utilizing this kind of nanocellulose.

  • Time :

Abstract:

Two-dimensional hybrid carbon nanosheets were synthesized and functionalized with various functional groups, which feasible produced unique thermal, mechanical, optical, and electrical properties. The lower generation (between G1 and G3) polyamidoamine (PAMAM) dendrimer was covalent functionalized to reduced graphene oxide through conventional chemical methods. The covalent layer by layer assemble with mercaptopropionic acid (MPA), PAMAM dendrimer and gold nanoparticles (AuNPs) on Au transducer consists of an inexpensive and straightforward strategy of developing a highly ordered multilayer three-dimensional (3D) open and fractal nanoarchitecture as a fast, ultra-trace determination of label-free DNA hybridization sensing[1]. Keen selections of AuNPs were encapsulated onto the PAMAM G1 functionalized on graphene oxide (GG1PD), by strong physicochemical interaction between AuNPs and -OH of rGO in GG1PD. Their morphologies, structures, electrochemical properties, and gene nanobiosensing performances were characterized and evaluated. AuNPs/GG2PD based probe displayed the best structural stability, lowest mobility on a solid surface with an increasing charge resistance, widest linear range (1.1×10−6 to 1×10−18 M), and the lowest limit of detection (1.87×10−19 M) in comparison with both AuNPs/GG1PD-based and AuNPs/GG3PD-based probes[2]. This work will provide a new candidate for the development of metal nanoparticles functionalized dendrimers with inorganic nonmetallic nanomaterials as cores with 3D fractal nanoarchitecture and promising electrochemical gene nanobiosensing platforms based on dendrimer-nano inorganic hybrids with 3D nanoarchitectures and LBL assembly for fast and ultra-trace detection of label-free DNA hybridization with potential application in bioanalysis and medical diagnosis of genetic disease.

  • Time :

Abstract:

Brucellosis is one of the most common zoonoses, which affects multiple species. Brucella suis is responsible for a substantial proportion of infections in humans. The B. suis biovar 1 infection in cattle is an emerging veterinary an public health problem. Little is known about the presence of B. suis in wild fauna. In Argentina seroprevalence of Brucella sp was reported in fox (Lycalopex gymnocercus), wild boar (Sus scrofa), European hare (Lepus europaeus), armadillos (Chaetophractus villosus) in Buenos Aires, La Pampa and Patagonia province. Brucella suis biotype 1 was isolated from hare in Buenos Aires and La Pampa. It has also been isolated from armadillos in La Pampa. Hares infected with B. suis biovar 1 exhibited typical lesions of the disease. Nevertheless armadillos have not macroscopically observable lesions. However, histology revealed small internal abscesses (1 mm) in the parenchyma of liver and spleen. Under experimental conditions Brucella was isolated from the spleen, liver, mesenteric lymph node, uterus, urine and testicles samples. In Argentina, as in many countries, there are an underestimation and a sub notification of human cases of brucellosis. From 2009 to 2011, 1040 sera from human resulted positive by serology to brucellosis. Blood cultures were perform in some patients, being able to isolate B. suis biovar 1 in 53% of them and B. abortus in 27%. Although the source of infection is unknown in all of these cases. In rural areas armadillos and hare are hunted and consumed, by humans. However until now it is not available evidence indicating that armadillos and hare can transmit brucellosis to domestic animals, humans or other wildlife by direct contact The route of transmission to humans could be the ingestion of contaminated food, products or undercooked meat or by manipulating these animals at the time of extracting their skin and offal. Only careful and systematic monitoring will help to know the impact of wild animals on the transmission of this zoonotic disease.

  • Title:Waist / Height Index in Children 7 to 11 Years with High Birth Weight and its Relationship with Sex, Age and Diet
  • Time :

Abstract:

Obesity (OB), considered as one of the Non-Transmissible Chronic Diseases, has as its fundamental characteristics that of being prevalent at a global level, increasing in number, affecting developed and developing countries, affecting both genders, and all ages and social groups.
Objective: To identify if high birth weight is a predictive factor (risk factor) for abdominal obesity in children 7 to 11 years old, and its relationship to gender, age and diet. Method: A case-control descriptive study was carried out with children born between January 1992 and December 1995, in order to identify early risk factors (atherosclerotic accelerators) such as abdominal obesity in children aged 7 to 11, and who have a history of macrosomia or high birth weight, as well as their relationship with gender, age and diet.
Results: It was observed that the waist/height value was normal in 60.8% of the study group and in 64.00% in the control group. The difference between groups, gender, and age was not significant (P=.6859). As regards the diet in the study group (macrosomic), there was no significant association between the type of diet and waist circumference/height values, with an_ 2=0.223 and P=.6373 (not significant). In the control group (with normal weight at birth), it was found that there is a significant statistical association between the type of diet and waist circumference/height values. This means that it can be stated, with 95% reliability, that the type of diet is associated with waist/height values.
Conclusions: High birth weight is not a predictive factor (risk factor) for abdominal obesity (increased waist/height index). Gender and age are independent for abdominal obesity (macrosomic and normal weight at birth). The diet in high birth weight children is not related to the index waist-height index, which is not the case in those born with normal weight under the same conditions. The marked increase in abdominal obesity (Waist/height index) in children between 7 and 11 years old in both groups is worrying.

  • Title:Bioactivity of Anthocyanins and Their Stability as Natural Food Colorants: The Case of Pomegranate Juice
  • Time :

Abstract:

The widespread use of pomegranate juice (PJ) is due not only to its health benefits, which originate to its flavonoid content, but also to its bright red color. Anthocyanins (ΑCNs) are the chemical group mainly responsible for both functions that unlike other flavonoids, are characterized by rearrangements in response to pH changes. The great benefit in the human diet is originated from the fact that they can be absorbed as intact molecules without undergoing metabolic changes.
The role of ACNs as food coloring agents has drawn great interest in exploring natural food colorants as a promising alternative to synthetic food dyes. Recently, synthetic food dyes attracted public concerns regarding their potential impact on human health, specifically neurological and behavioral functions. So far, ACNs use as food colourants has been limited due to their low stability, which can be influenced by several factors such as their structure, pH, temperature, light, copigments, metal ions, enzymes, oxygen, ascorbic acid and sugars, among others. The copigmentation is one of the most important factors influencing plant pigmentation in vivo. It causes stabilization of the coloured anthocyanin structural forms and consequently enhances their colour. Co-pigments are colourless on their own, but when added to anthocyanin solution, they increase the colour intensity and the stability of the solution. Therefore the exploitation of co-pigments impact on ACNs stability in food systems, is of great interest for the food industry and the consumers.

Abstract:

Anthocyanins (ACNs) are water soluble natural pigments, which not only impart color to the foods, also exhibit multiple healthy effects. Black soybean (Glycine max (L.) Merr.) have been used as nutritionally rich food and folk medicine and its seed coat contains abundant levels of anthocyanins (mainly cyanidin-3-O-glucoside; Cy3G). In order to illustrate the hypoglycemic mechanism of the dietary anthocyanins from black soybean, the effects of black soybean seed coat extract (BSSCE) and cyanidin-3-O-glucoside (Cy3G), he major anthocyanins of BSSCE on regulation of Akt and GLUT4 in L6 rat skeletal muscle cells were studied. BSSCE and Cy3G significantly augmented the glucose uptake in L6 myotubes in comparison to the normal control (p < 0.05). Especially, at 150 μg/mL ofBSSCE and40 μMofCy3G treatment, the2-NBDG uptake level were increased by 1.81fold and 1.90-fold with that of normal control, respectively. Furthermore, the expressions of p-Akt and GLUT4 were also increased and theGLUT4 translocation was promoted by BSSCE and Cy3G, which indicated the involvement of the Akt/GLUT4 signal pathway in the hypoglycemic mechanism ofBSSCE. Overall findings revealed that Cy3G enriched BSSCE might be a promising functional food or medicine for the treatment of T2DM and its associated metabolic disorder. Biography:

Abstract:

Enzymatic reactions refer to organic reactions catalyzed by enzymes. This review aims to enrich the documentation relative to enzymatic reactions occurring during the anaerobic degradation of residual organic substances with emphasis on the structures of organic compounds and reaction mechanisms. This allows to understand the displacement of electrons between electron-rich and electron-poor entities to form new bonds in products. The detailed mechanisms of enzymatic reactions relative to the production of biomethane have not yet been reviewed in the scientific literature. Hence, this review is novel and timely as it discusses the chemical behavior or the reactivity of different functional groups, thereby allowing to better understand the enzymatic catalysis in the transformations of residual proteins, carbohydrates, and lipids into biomethane and fertilizers. Such understanding allows to improve the overall biomethanation efficiency in industrial applications.

  • Time :

Abstract:

Milk-derived bioactive peptides can improve the treatment of many diseases, behaving as antihypertensive, antimicrobic and antioxidant agents. This study was focused on new peptides evaluated for their antioxidant properties and mechanism of action cell enviroment. Peptide enriched fractions were extracted from fermented milk and purified in order to obtain the sequence of the included bioactive peptides. Twenty-three new peptides were identified and synthesized by solid phase procedure. Their antioxidant properties were analysed in vitro and in a cellular model using Caco-2 cells. Among these peptides, N-15-M, E-11-F, Q-14-R and A-17-E were selected in order to estimate their antioxidant capacity on Caco-2 cells both as protection against oxidative stress and inhibition of ROS production induced by TbOOH. In order to understand the possible action of the peptides on Keap1-Nrf2 pathway, which is involved in the response to oxidative stress, the translocation of Nrf2 from cytosol to the nucleus was taken into account. N-15-M, Q-14-R and A17-E were able to activate the Keap1-Nrf2 system, as shown by the higher amount of Nrf2 found in the nucleus with respect to the control. This modulation led to overexpression and increase of activity of antioxidant enzymes such as TrxR1, GR, NQO1 and SOD1. The interaction of these peptides with Keap1 was also studied through molecular docking analysis. The results confirmed that N-15-M, Q14-R and A-17-E interact with the residues of the Keap1 pocket involved in the binding with Nrf2, acting as disruptor of Keap1-Nrf2 interaction.

  • Title:Chrysin Mitigated Obesity by Regulating Energy Intake and Expenditure in Rats
  • Time :

Abstract:

Obesity is characterized by an imbalance between energy intake and energy expenditure. Chrysin is a flavonoid found in plant extracts from Passiflora family, honey and propolis. Molecular modeling studies were carried out to determine the binding potential of chrysin to pancreatic lipase (PL). Further, the kinetics of inhibition of PL and effect of chrysin on the absorption of fats and sucrose preference test was studied in normal rats. Obesity was induced in the rats by feeding of high fructose diet (HFD) for 16 weeks. The rats were divided into six groups: normal control, HFD control, orlistat and three doses of chrysin (25, 50 and 100 mg/kg body weight). Body weight, body mass index (BMI), abdominal circumference-thoracic circumference (AC/TC) ratio, calorie intake, adiposity index, fecal cholesterol, locomotor activity and histopathology of the adipose tissue of the rats were determined. The docking score of chrysin to PL was found to be -8.03. Chrysin inhibited PL competitively (IC50= 0.018±0.006 mM). It significantly reduced the absorption of fats and sucrose preference in rats. Chrysin significantly decreased the body weight, BMI, AC/TC ratio, adiposity index, calorie intake and significantly increased the fecal cholesterol excretion of rats. Chrysin significantly increased the locomotor activity of rats in a dose-dependent manner. The histopathological examination of the adipose tissue revealed reduced hypertrophy of adipocytes in rats treated with chrysin when compared with HFD control. Thus, chrysin seems to be a promising molecule to combat obesity by inhibiting pancreatic lipase, reducing bingeing on sugars and increasing the locomotor activity of rats.

  • Title:Trends in Sugar-Sweetened Beverages: Are Public Health and the Market Aligned or in Conflict?
  • Time :

Abstract:

The adverse effect of consuming sugar-sweetened beverages on the risk for developing obesity has been cited as an example of market failure, justifying government intervention in the marketplace, usually in the form of taxation. Food and beverage producers typically resist regulation putting them in conflict with public health advocates. In Australia, a recent analysis of market research data has shown that per capita volume sales of sugar-sweetened beverages have been declining for at least 22 years. Consequently, the per capita contribution of sugar-sweetened beverages to the sugar content of the national diet has fallen by nearly 30 per cent. Per capita volume sales of non-sugar-sweetened beverages have increased over this period, especially those of bottled water which have increased exponentially over the last decade. Volume sales of non-sugar-sweetened beverages have exceeded those of sugar-sweetened beverages in Australia since 2015. These significant changes in the pattern of beverage sales are consistent with obesity prevention recommendations but have occurred in the absence of significant government regulation. Rather, they appear to reflect market forces at work. Contrary to the market failure argument that consumers fail to appreciate the links between their choice of beverage and its health consequences, changes taking place in the beverage market appear to be driven by consumer interest in health and wellness. Thus, the public health challenge in relation to sugar-sweetened beverages may have less to do with regulating the market and more to do with harnessing it.

  • Time :

Abstract:

The use of firewood is an old tradition in Brazil. In the south and southeast regions,firewood is used by customs and due to the colder climate. On the other hand, the northern and northeastern regions use firewood for economic reasons. Many people use it because they believe that firewood makes food tastier. Others because the wood stove brings people closer. However, throughout the country firewood or charcoal is used in the preparation of the barbecue. This type of food is most common on weekends and parties. The stoves and barbecues used are the most varied, from very simple to the most sophisticated. As well as firewood, which comes from both deforestation and reforestation. Firewood characteristics, per capita consumption, and distribution percentage vary widely within the country. Although LPG is the most used fuel in Brazil, a significant portion of the population, about 11 million households use firewood. This study will present and explore the data regarding the use of firewood for cooking.

  • Time :

Abstract:

The analysis of different types of feed for feeding various farm animals from the point of view of their chemical safety was carried out. It has been established that the most toxic feed among farm animals is included in the diet of beef and dairy cattle. Thus, the main reasons why the World Health Organization at one time evaluated red meat as a possible carcinogen for humans become apparent. Among the toxic impurities in the feed for these two groups of animals, mycotoxins, especially lipophilic ones as well as polyaromatic hydrocarbons (PAHs) and persistent organic pollutants (POPs), pose the greatest danger. These substances pose a threat to animal health andnproductivity, are capable of being accumulated and transferred to animal products and thus can be incorporated into human food chains. A comparative analysis of the sorption capacity of feed adsorbents of different nature and polarity with respect to lipophilic sorbates was carried out. Examples of effective removal of POPs from dairy and meat products in cattle herds are given. The strategy and tactics of using cost-efficient non-polar adsorbents to protect the digestive tract of farm animals and, indirectly, human health from the harmful effects of lipophilic toxins from feed for farm animals are discussed.

  • Title:Multidisciplinary Approach to Obesity: Aerobic or Resistance Physical Exercise?
  • Time :

Abstract:

An integrated treatment based on dieting, physical training and cognitive-behavioural psychotherapy is an effective tool to reduce obesity and its consequences. However, the feasibility of this approach is problematic. This study aims to compare two multidisciplinary programs used to improve weight loss. Fifty-two obese individuals were subjected to an Enhanced Lifestyle Counselling associated with, according to their own choice, dieting (N =11), or dieting þ aerobic training (n = 18), or dieting þ resistance training program (n = 23). The study experiment spanned 16 weeks divided into two phases. The first phase lasted 04 weeks and was oriented to enhance motivation and establishing changes in behaviours related to dietary and sedentary lifestyle. The second phase lasted 12 weeks and was oriented to add aerobic or resistance training. Body compositions, cardiovascular disease risk factors, and cardio-respiratory fitness were assessed. Data demonstrated that all obesity treatment programs were able to improve all studied variables. Weight loss levels were -6.03 ± 2.08, -10.5 ± 2.33, and -9.37 ± 1.99 kg in Dieting, DAT and DRT groups, respectively. Our results noted also that exercise training could play an important role in reducing obesity and its consequences. Nevertheless, modifications were more important in DRT at the explosivity and muscle strength and in DAT at fat percentage, aerobic capacity, SA, and CVR factors. Conclusion: The current evidence noted that both multidisciplinary weight loss programs were efficient in the treatment of obesity and its comorbidity. Moreover, the use of aerobic exercises was more effective in reducing body fat and improving cardiorespiratory fitness. However, using resistance exercises appeared to be more appropriate to enhance the muscle potential.

  • Title:Research for Behavior Evolution Pattern of Diseased Shrimp Based on Improved ResNet-50 Convolutional Neural Networks
  • Time :

Abstract:

Such huge amount of defective and diseased shrimp exists in the crowded shrimp clusters after harvest. To ensure the quality of fresh shrimp and safety of the eaters, it is necessary to remove these impurities in time. The process was completed traditionally by using machine vision technology, our team published many related papers and developed an on-line shrimp inspection machine which has been put into application in the Xiaoshan shrimp processing factory. However, shrimp has a long growth cycle, which stage does the diseased shrimp produce or what is the relationship between the shrimp behavior and the final quality of shrimp? The problem is fantastic and deserved to study from the perspective of fundamental research and shrimp abnormal behavior evolution pattern. To this end, the shrimp abnormal behavior evolution pattern was studied with diseased shrimp. Firstly, the underwater machine vision system was constructed based on shrimp breeding environment and shrimp behavior, including high-performance computer, high resolution camera, waterproof LED light source, underwater sensors. Secondly, the behavior of shrimp body was monitored within 24 hours a day respectively under infecting of nine virus types, including TSV、WSSV、SHIV、YHV、IMNV、CMNV、MBVD、HPV、BMNV. Then, correspondingly snap 30 days video of shrimp behavior independently, saved these videos and made some video processing jobs. Traditional ResNet-50 convolution neural network was improved, the soft-Max layer is modified and delete all connection layers. Treat the last convolution and pooling layer as a final layer and thus construct a visual feature extraction, which is used to display the visualization results, make it adapted to the special shrimp appearance characteristics. Finally, through experimental verification, under the nine types of virus, the movement observation respectively of 100 shrimp was snapped, we divided them into ten groups, each group recorded 10 section 20 min video. The shrimp behavior all show some abnormal performance with the infection of virus, and the degree of abnormal behavior that increases with the rising of concentration. The proposed CNN can build a model to learn the correlation between shrimp behavior and quality of shrimp. This experiment also confirmed all the shrimp infected with virus, would undermine the shrimp body immune system and lead to shrimp irreversible damage to the nervous system, resulting in the growth process of shrimp to produce abnormal behavior mode. Experiment results showed that the appearance color of some infected shrimp are more noticeable, and some in the abdominal muscle texture produce evident in the evolution. The results confirmed that infected shrimp show some abnormal behavior. Moreover, the evolution rule of shrimp abnormal behavior is clear along with the deepen of ResNet, which also related to the final quality of harvested shrimp, leading to such huge amount of diseased shrimp. This will pose a great threat to the life and safety of those who eat it.

  • Time :

Abstract:

Psyllium has been used worldwide to improve the symptoms of constipation, irritable bowel syndrome and diarrhea. It has been recognized as a cholesterol-lowering agent to be used in the treatment of hypercholesterolemia. Given psyllium’s ability to reduce low-density lipoprotein (LDL) cholesterol levels, the National Health Surveillance Agency (ANVISA) and the Food and Drug Administration (FDA) authorize manufacturers of food products to include health claims for psyllium on their labels, provided that these products contain the minimum amount (content) of the referred fiber required for health claims on their labels. Health claims add value to products, making them competitive, and are used by marketing departments to arouse consumers’ attention and influence their buying decisions.
In addition to offering fibers to the consumer, products that contain psyllium also include health claims on their labels, which is an important marketing advantage, since most consumers seek food products with functional properties. Psyllium also contains antioxidant compounds (phenolics and flavonoids), and the frequent intake of this fiber contributes to the reduction of fasting and postprandial blood glucose concentrations, causes satiety, reduces hunger and the urge to eat. It also assists in weight loss.
Due to the benefits of this fiber, several studies have investigated the incorporation of psyllium into bakery and dairy products.

  • Title:Expanding the Toolbox for Food Microbiologists with New Stable Fluorescent Laboratory Control Strains
  • Time :

Abstract:

Bacterial control strains are a critical component in microbiological methods, ensuring the media, reagents and related components of a test method are performing in a manner to ensure the quality of the analytical results. The use of naturally occurring bacterial strains as positive controls during testing is counter-indicated due to the risk of sample cross-contamination. Taking advantage of the target site specificity of transposon Tn7, we developed a collection of strains which express Green Fluorescent Protein (GFP) at high-levels, permitting the rapid screening of the following species on selective or non-selective agar plates: Escherichia coli O157:H7, Shigella sonnei, S. flexneri, Salmonella enterica subsp. enterica serovar Gaminara, S. Mbandaka, S. Tennessee, S. Minnesota, S. Senftenberg and S. Typhimurium. These new engineered strains that fluoresce when irradiated with Ultraviolet light, are easily identified and differentiated from naturally occurring pathogens. Importantly, performance testing in our laboratory and several FDA field laboratories showed that none of those strains containing the GFP marker displayed the potential of becoming a mixed population of fluorescent and non-fluorescent cells, making them suitable laboratory control strains for food microbiologists. We are employing the same approach to engineer additional reference strains for the FDAs’ Compendium of Microbiological Methods, the Bacteriological Analytical Manual (BAM), to exhibit the same stable fluorescent phenotype. Having a suite of control strains with stable, easily identifiable phenotypes like fluorescence eliminates the need to perform the time consuming and expensive confirmatory testing required when naturally occurring bacterial strains are used in microbial methods.

  • Title:Mustard Grains, Germination, Phenolic Compounds and Antioxidants: How Can They Interact?
  • Time :

Abstract:

Mustard grains are known for centuries as an important commercially condiment in all of the world with a huge variety of use and applications. Our research group has been studying this promising grain to improve its biological properties. To begin, choosing the best solvent combination to recover phenolic compounds with antioxidant activity potential was encouraged. We reported for the first time an optimization study for recovery of phenolic compounds from mustard grains in order to obtain extracts with better antioxidant properties. Continuing studies, germination was chosen as a natural process due the actual tendency to valorize the spontaneous process and knowing that the germination is an efficient and economical process that promotes dynamic and complex positive changes in bioactive compounds and nutritional quality of grains. The main questions raised in our research were: How could we germinate mustard grains since changes during the process are peculiar for each grain? How germination affects the antioxidant potential and phenolic compounds composition? So, the first step was to analyze different germination parameters correlated with antioxidant potential. Also, to better understand those complex transformations, our research group investigate how the variation of free and insoluble-bound phenolics affected the antioxidant properties of mustard grains when submitted to different germination parameters. The identification of the bioactive compounds by chromatography techniques was also important to the final discussion. Given the positive results obtained, we can conclude that germinated mustard grains have the potential for application as a functional and nutraceutical food.

  • Title:Changes in Nutrient Absorption in children and Adolescents Caused by Fructans, Especially Fructooligosaccharides and Inulin
  • Time :

Abstract:

Introduction
Fructans, such as inulin and fructooligosaccharides (FOS), have several effects on human health owing to their prebiotic character, including anti-microbial and anti cancer effects, and to their influence on the absorption of minerals, which is very important in childhood and adolescence.

Objective
Our aim was to review the role of some fructans in the absorption of vitamins and minerals in children and adolescents.

Methods
We conducted a narrative review of the absorption of nutrients with fructans. We collected quantitative data for our thematic analysis, which was performed using the electronic databases Medline, Lilacs, Web of Science, and Scopus from January 2000 and January 2019. This review comprises a total of 10 articles.

Results
Few studies were found regarding the use of prebiotics and nutrient absorption in children. Studies on calcium, iron, magnesium, and vitamin D were the most prevalent.Some studies reported that FOS appears to increase calcium uptake in the gut and stimulates the growth of bifidobacterium in the colon, reducing iron intake by enteric pathogens, and increasing the absorption of these minerals. Others reported an improvement in the absorption of vitamin D and E with inulin.

Conclusion
Consumption of fructans improves the health of the microbiota, altering the absorption of some nutrients.

  • Title: Fermented Brown Rice and Rice Bran Delayed Onset of Spontaneous Type 1 Diabetes in NOD Mice
  • Time :

Abstract:

Brown rice and rice bran fermented by Aspergillus oryzae (FBRA) is a processed food that is rich in partially digested fiber, rice bran-derived phytic acid, and plant polyphenols. Its anti-inflammatory effects have been reported in several animal disease models. Type 1 diabetes is an autoimmune disease caused by Th1-mediating immune attack for pancreatic islets including cytokine-mediated production of reactive oxygen species (ROS). Chronic pancreatic inflammation induces death of islet  cells and depletes insulin secretion, resulting in onset of diabetes. In addition to genetic and immunologic factors, environmental factors such as infection, diet and microbiota can also contribute to the pathogenesis. Possible targets of functional food in this type 1 diabetes include: 1) islet-specific T lymphocyte activation; 2) islet-targeting lymphocyte infiltration; 3) cytokine-mediated inflammation or ROS production; 4) regeneration of damaged islets or apoptotic cell death of damaged islets. Here, I will introduce our recent work showing the suppressive effects of dietary administration of FBRA against spontaneous onset of type1 diabetes in NOD female mice. While control diet-fed mice showed glucosuria and hyperglycemia at around 20 week of age, dietary administration of 0.5% FBRA significantly delayed the onset of these diabetic features. The FBRA-fed group at 30 weeks of age kept higher ratio of intact islets and showed significantly lower insulitis score compared to the control diet group, with dose-dependency from 0.25% to 0.5% dietary concentration of FBRA. These results suggest that dietary FBRA delayed the spontaneous onset of diabetes in NOD mice probably through maintaining the number of intact islets. How do the FBRA or its components affect the process of diabetes is still unclear, examined results of FBRA on the T cell population and the expression of Pdx1 and related molecules which are known to involve islet cell viability, death, and regeneration, will be discussed.

  • Time :

Abstract

The worldwide concerns and heightened sensitivity to the emerging drug-resistant superbugs have energized scientists to search for new alternatives for in-feed antibiotic growth promotor. Powered by consumer demand for natural products and due to their beneficial effects on growth performances, phytogenics became very popular and favorable alternatives. Yet, their mode of action was not fully defined. Here, we showed that supplementation of phytogenics in water or in feed improves
feed efficiency in broilers and modulates hypothalamic and peripheral metabolic pathways (reduction of hepatic fatty acid synthesis, mobilization of fat store, and enhancement of muscle protein synthesis), which might explain, at least partly, their effect on feed efficiency improvement in broilers.

  • Title:Association of Beverage Consumption Types with Weight, Height, and Body Mass Index in Grade 3 Children in Northern Taiwan: a Cross-Sectional Study
  • Time :

Abstract:
Background:
The increasing prevalence of convenience and beverage stores in Taiwan provides an environment for children to access different beverages types. To our knowledge, the relationship between beverage consumption types and anthropometrics in children has not been reported in Taiwan. This study aims to examine the association of consumption frequency of beverage types that children commonly drank with anthropometrics in grade 3 children in Northern Taiwan.
Methods:
A cross-sectional study was conducted in Taiwanese third grade students to examine the association between the consumption frequency of beverage type and anthropometrics. Samples were collected from 10 Northern Taiwan elementary schools. Parents of the 515 children completed a questionnaire with written instructions voluntarily, which was designed to collect demographics, frequency of consumed beverage types, and anthropometrics. This study is novel because beverage types were categorized based on sugar and protein contents, namely nutritious (N), sugar (S), nutritious and sugar (NS), and non-nutritious and sugar-free (NS-free). The differences in height and body weight between intake frequencies within each beverage type were determined using analysis of variance (ANOVA) test or nonparametric statistics, dependent on the confirmation of normal data distribution.
Results:
Height and weight of children consuming the most N beverages fell in the highest respective percentile compared to those who did not consume them (p values P = 0.001 and 0.035, respectively). Consumption of NS and S beverages were not associated with height, body weight, and body mass index (BMI). Children who consumed more NS-free beverages were significantly heavier (p = 0.016) and had a larger BMI (p = 0.001).
Conclusion:
This is the first study conducted on third-grade children in Taiwan showing that beverage consumption type was associated with anthropometrics. In conclusion, nutritious beverages appear to be a better choice in terms of growth in children. Nevertheless, additional related studies, including an overall assessment of children’s calorie and nutrient intakes and related dietary behaviors, are warranted to provide more helpful information for policymakers.

  • Title:Microencapsulation Efficiency and Gastrointestinal Release of EPA and DHA as Affected by the Wall Material.
  • Time :

Abstract:

Two types of fish oil microcapsules (monolayered (MO) and multilayered (MU)) have been developed for enriching meat products in omega-3 fatty acids, differing in the covering layer: maltodextrine and chitosan+maltodextrine, respectively, for MO and MU. In the present study, the influence of the covering layer on the efficiency to encapsulate omega-3 fatty acids, and the release of eicosapentaenoic (C20:5 n-3, EPA) and docosahexaenoic acids (C22:6 n-3, DHA) during the gastrointestinal tract has been evaluated. The microencapsulation efficiency of fish oil (percentage of encapsulated oil in relation to total oil in microcapsules) was higher for MO (88.88 ± 0.46%) than MU (55.43 ± 4.60), which may be ascribed to the loss of part of the oil during the formation of the multilayer structure in the spray-drying process. Nevertheless, the fat percentage (7-9%) and the quantities of EPA+DHA (12-13.50 mg/g microcapsule) were similar in MO and MU. This is due to a higher percentage of external oil in MU than in MO. Regarding the results on the in vitro digestion analysis of MO and MU, the quantities of EPA+DHA released at the end of oral and gastric phases were higher in MO (2.52 and 1.00 mg/g microcapsule) than in MU (1.34 and 0.71 mg/g microcapsule), while at the end of the intestinal phase the release of these fatty acids was higher in MU than in MO (10.68 and 8.76 mg/g microcapsule), indicating a probable major bioaccesibility of EPA+DHA with MU. These results may indicate the influence of the covering layer of the fish oil microcapsules on the microencapsulation efficiency and gastrointestinal release of the encapsulated omega-3 fatty acids, pointing out a major resistance of the multilayer structure of chitosan-maltodextrine to the gastric conditions despite its less microencapsulation efficiency.

  • Title:Non-Enzymatic Sensors for Glucose Determination in Bio-Fermentation Processes
  • Time :

Abstract:

Over the past few years, the glucose monitoring has been of great interest for clinical diagnosis, food analysis, personal care and control of bioprocesses. Enzymes-based biosensors well meet the requirements of good selectivity and high sensitivity, but the drawbacks arising from their thermal/chemical instabilities and the complex fabrication procedures have hindered their further progress for continuous monitoring. Non-enzymatic glucose sensor functioning is based on direct oxidation of glucose, where the key factor is the electrocatalytic activity of the electrode material which affects their sensitivity and selectivity. It is possible to achieve the enzymeless electro-oxidation of glucose with some transition metal-based catalysts. Among several catalysts so far proposed, electrochemical glucose sensors based on CuO, and Cu2O nanoparticles, offer many advantages compared to enzyme-based glucose sensors, and can also be less expensive compared with the ones based on noble metal nanoparticles. Copper-based sensors show a low detection limit, quick and reproducible amperometric response, as well as a wide linear range and low overpotential, due to their great ability to perform electron-transfer reactions. Here, we present a study focused on the synthesis of a new electrocatalytic material based on CuO and Cu2O nanostructures modified screen printed carbon working electrodes, prepared by an easy and cheap wet precipitation method, and to optimization of its electrochemical properties towards the glucose oxidation. The proposed sensors should have advantages such as low cost, simplicity, high stability, reproducibility and good selectivity for the detection of glucose in many application fields such as in clinical diagnostics and in biomass fermentation processes.

  • Time :

Abstract:

Proteins are widely used in the food industry since they are the essential building component of many food structures i.e. emulsion, foam,and hydrogel.In the last years, a global trend towards environmentally friendly proteins, such as plant-based proteins and protein from marine byproducts is observed. This study aims to explore the foaming properties of fish skin gelatin (FG) and pea protein (PP) at pH 7 after ultrasound treatment. Foams were prepared at different ratios FG:PP (100:0 – 50:50 – 0:100) by ultrasound treatment followed by mechanical stirring. The physical stability of foam was explored by visual analysis and by Turbiscan®, the interfacial properties by pendant drop and rheological approach whereas the presence of the protein on the O/W interface was investigated by confocal laser scanning microscopy. Globally, we observed that pea proteins give more stability to the foam, by playing a major role at the air-water
interface. The possible future applications, as well as the importance of this new mixed system to tailor new materials in the food industry, are discussed in the last part.

  • Time :

Abstract:
This study reports on 3-dimensional (3D) imaging technologies that reconstruct the shape of both live cattle and beef carcasses. The 3D imaging technology for live cattle assesses hip height (cm), fat depth (mm) and muscle score and for beef carcasses assesses lean meat yield (%). A supervised machine learning approach using non-linear regression algorithms have been developed to assess the traits on both live cattle and carcasses. To develop the algorithms observed values are compared with the 3D assessments. The observed live cattle assessments are measured hip height, ultrasound scanning of fat depth and objective assessment of muscle score by accredited assessors; and the observed carcass assessment is computed tomography (CT) scanning of boned out primals to estimate lean and fat tissue. Cognitive perception of humans supports the view that assessors leverage shape rather than distance (e.g., when ascertaining a visual muscle score of beef cattle). Therefore, it is advantageous to represent the body shape beyond 2D and leverage 3D shape representations as curvature, which is one of the core novelties of the research. An example of predicting carcass traits from live cattle assessments before slaughter will be presented.

  • Title:Evaluation of the Hygroscopic Capacity and Antioxidant Activity of Fruit Flour from the Aiphanes Aculeata Palm
  • Time :

Abstract:

Currently, the development of new foods which have health benefits and with nutritional values has increased. The presence of certain substances such as phenolic compounds present in foods of plant origin, help in the prevention of diseases and can have preventive and curative effects on physiological disorders in humans due to their antioxidant action. Therefore, the present study aimed to evaluate the hygroscopic behavior of the flour of the fruit of the palm Aiphanes aculeata, belonging to the family Arecaceae, as well as to evaluate its antioxidant activity. To obtain the flour, the fruit pulp was dried in an oven at 60oC, and then the hygroscopic properties were evaluated for water absorption index (IAA), water solubility index (ISA) and absorption index in oil (IAO). To obtain the hydroalcoholic extracts of the flour, 70% (v/v) ethyl and methyl alcohol were used as extracting agents to evaluate in which solvent there would be the best extraction of the phenolic compounds and the best antioxidant activity by the DPPH test. The antioxidant capacity was expressed as the concentration of antioxidant needed to reduce the initial number of free radicals by 50% (EC50), with values expressed in µg/mL. For the extract obtained with ethanol, the EC50 was obtained of 152.67 ± 31.33 µg/mL whereas for methanol, the EC50 was 210.67 ± 15.96 µg/mL. The hygroscopic properties for the IAA, 3.75 ± 0.62g water/g d.m.; for ISA 51.73 ± 3.20% and for IAO 3.11 ± 0.36g oil/g d.m. In this way, the ethanolic extract obtained a greater efficiency of extraction of the bioactive compounds in relation to the methanolic extract, demonstrating better antioxidant activity and great potential to be applied in the formulations of new products, the results of the hygroscopic properties of the flour showed excellent technological quality.

  • Title:Production of Hydrophobins from White Rot Fungus Pleurotus Ostreatus
  • Time :

Abstract:

Hydrophobins are small, surface-active, cysteine-rich proteins produced by filamentous fungi. They are able to assemble spontaneously into amphipathic monolayers at hydrophobic-hydrophilic interfaces; they lower the surface tension of medium and stabilize foams. Hydrophobins isolated from GRAS cleared edible mushrooms like Pleurotus ostreatus can be used industrially for various purposes like food foams, biosurfactants, biosensors, flavor stabilizers, pharmaceutical formulations, drug delivery systems etc. In consideration with industrial importance of the protein, the objective of this research work was to improve their process yield. In this study Pleurotus ostreatus was grown in submerged liquid fermentation (SLF) using different media like Potato Dextrose Broth (PDB), Yeast maltose and glucose (YMG), Basal minimal medium (BMM), Schizophyllum commune minimal medium (ScM). Class I Hydrophobin like proteins (HYD-LPs) were precipitated using Trifluroacetic acid (TFA). Among different media used for fermentative growth of P.ostreatus, YMG was found suitable for production of hydrophobins with highest yield of 1.86mg/g of biomass. These purified HYD-LPs produced stable foams with half decay time of 70 min, emulsions produced by these proteins with olive oil were stable for many days (EI 81%) and their amphipathic nature was studied by contact angle (CA) measurement of water on Teflon. HYD-LPs layered on Teflon reduced CA of water by 17.68%. P.ostreatus was also grown in solid state fermentation (SSF) on agro-industrial waste oil cakes of coconut and sesame obtained from local market. Moisture content of SSF process was maintained at 75%. Sesame oil cake gave higher yield of HYD-LPs (3.85 mg/g of biomass). Production in SSF was 2 fold higher than that in SLF. This work underlined the suitability of SSF over SLF for higher production of HYD-LPs. To further improve the productivity of HYD-LPs, media optimization methods are underway using various statistical methods.

  • Time :

Abstract:

This study investigated the effects of the addition of onion waste fractions into gluten-free (GF) bread to promote its health benefits. 5% of the control (C) GF flour blend was replaced with three waste fractions in the form of: fried onion (FO), dried onion (DO) and onion peel (OP). Antioxidant activity, content of flavonols and total polyphenols of breads increased in the following order: C < FO < DO < OP. No differences were observed in sensory analysis. We found that quercetin glycosides, dimers and trimer in OP-bread, determined according to their mass spectra, decomposed during baking and released free quercetin, which points to their thermal instability. Cross-over study revealed that consumption of OP-bread significantly increased (p < 0.05) antioxidant activity of consumers’ blood compared to control bread consumption, indicating good bio availability of flavonols. Results suggest incorporation of OP into GF bread can increase its biological value with satisfactory sensory acceptance. Biography:

  • Title:The Role of the Brazilian Flora in the Chemical Profile and Biological Activities of Propolis
  • Time :

Abstract:

Propolis is a bee product containing plant resins and beeswax. Propolis and its isolated constituents exert biological effects such as antimicrobial, anti-inflammatory, antidiabetics, immunomodulatory, wound healing, antitumor and antiulcer. These effects are accounted for substances contained in resins collected by bee foragers from plant exudates or young tissues. In Brazil, several propolis types from stingless bees (meliponines) and Africanized honey bees are produced in commercial scale. An emerging market of propolis from stingless bees is gaining relevance among apiculturists in Brazil. Several papers have investigated the composition and medicinal properties of meliponine propolis from several parts of the country. Comparing with honey bee propolis, similarities and differences have been noticed in the composition of Brazilian meliponine propolis. Two types of Brazilian propolis from honey bees stand out due to the amounts produced and commercialized, both in the domestic and international markets: green propolis, produced in southeast and Central Brazil, and red propolis, from the northeast mangroves. The former contains resin from Baccharis dracunculifolia and the latter contains resins from Dalbergia ecastapyllum. Artepillin c, from Brazilian green propolis, is one the two propolis constituents most studied for their biological properties. Red propolis contains chiefly chalcones, isoflavones and pterocarpans. Other types of Brazilian honey bee propolis have been characterized: a) green propolis, derived from Mimosa tenuiflora, produced in dry forests from the northeast semi-arid; dark propolis from northeast; b) black propolis from the Amazonian region, containing resin derived from Clusia species; c) yellow propolis from the “Pantanal” biome (southwest); d) brown propolis from the south, with varied composition and resins from Araucaria, Baccharis and Populus. A propolis produced in the Ceará state (northeast) contains triterpenoids and of phenolic substances, mainly flavonoids, such as chalcones, flavanones and flavonols (derivatives of kaempferol, quercetin, isorhametin and myricetin). The propolis extract has high antioxidant activity. Several constituents isolated from Ceará propolis have weak anti-HIV activity (17%-44% inhibition of the reverse transcriptase), while isorhamnetin has moderate activity (57% inhibition).

  • Title:Application of Innovative Methods for the Traceability of Organic Horticultural Crops
  • Time :

Abstract:

Different researches have been carried out over the years to investigate on new and reliable systems to test the authenticity of products obtained using organic cultivation methods. At the same time, the monitoring of some chemical components, deriving from primary and/or secondary metabolism of organic and conventional products, has highlighted the diversity induced by the two production techniques while the difference in fertilization practices has been shown to impact on the isotopic distribution of some elements present in fruits and vegetables, with particular reference to nitrogen. The INNOVABIO (‘Application of innovative methods for the traceability of organic farming products’) research project (Italian Ministry of Agricultural, Food and Forestry Policies n. 93173/12/22/2017) aims to build up an integrated system able to validate, through the acquisition of isotopic data and other chemical and biochemical parameters, the authenticity of organically managed horticultural produces. Experiments have been carried out at CREA-OFA and FEM labs on soil, leave and fruit samples of cauliflower grown at CREA-OF Monsampolo del Tronto (AP) by using six different fertilization treatments. Two organic treatments (“organic” and “1/3 organic”) were performed on a organically managed soil since many years. Three conventional treatments (“conventional”, “1/3 organic” and “2/3 organic”) were carried out on a formerly conventionally managed soil. Finally, one organic treatment “organic + agroecological service crops” was performed on a certified soil for organic farming within the experimental long-term field MOVE LTE (MOnsampolo VEgetable organic Long Term field Experiment). Preliminary results of the first year of project have showed that multivariate analysis of isotopic data combined with classical quality parameters (TSS, TA, cut resistance, L*, a*, b*, head height, head diameter, ascorbic acid content, total polyphenols, ORAC units) performed by Linear Discriminant Analysis gives the possibility to discriminate organic products from conventional ones thanks to the different isotopic signature impressed by the different nitrogenous source combined with the qualitative pattern of the crops, significantly affected by the different treatments.

  • Time :

Abstract:

Sugar palm (Borassus flabellifer) cultivated and its pulp, as well as immature endosperm, is consumed popularly consumed throughout Bangladesh. Objective: The aim of this study was to elucidate the anti-diabetic effect of immature endosperm on type-2 diabetic patients. Methods: First rat model was used, then effectiveness was tested on type-2 diabetic patients. Randomly selected T2DM patients (n=30) were orally fed immature endosperm of sugar palm (IESP) twice a day beside the regular dietary intake. Results: The current study showed IESP is rich in carbohydrate, fiber, sodium, potassium, and zinc. Nineteen phytochemicals, with known anti-diabetic effects, were found to be present in the IESP. Study results clearly showed that IESP significantly reduced fasting blood glucose (FBG) levels of experimental rats. The FBG levels returned within normal range by the end of the sixth week and also maintained the normal FBG levels even after withdrawn of the feeding of IESP. The human trial also showed that the mean fasting blood glucose (FBG) level was markedly reduced from 15.74 mmol/L to 10.53 mmol/L, over four weeks feeding period, among patients who had normal body mass index (18.5-24.9). Only 16.67% of diabetic patients had irregular FBG levels, whereas 10% didn’t show a significant reduction, and 6.67% was unsuccessful because of their irregular intake of insulin. The IESP was more effective on female (p≤0.001) patients than males (p≤0.05). Conclusion: The IESP could be considered anti-hyperglycemic fruit, and this might be due to its nutrient contents, especially phytochemicals, fiber, sodium, potassium, copper, and zinc.

  • Time :

Abstract:

The present work was focused on evaluating the resultant crude juices from the mechanical pressing of some agricultural and food industries by-products i.e., pomegranate leaves and peels and leaves of fig, guava and olive as a source of naturalistic antioxidants. The results indicated that the amounts of polyphenols, flavonoids, tannins and anthocyanins in crude pomegranate peels juices were markedly higher than those of other crude juices under study. The polyphenolic constituents in fig leaves, pomegranate leaves and peels, guava leaves and olive leaves were distinguished using HPLC. The major compounds found in all crude juices were gallic acid, ellagic acid, naringenin, ferulic acid and methyl gallate, respectively. Pomegranate peels crude juice exhibited the highest antioxidant activity in comparison with other crude juices under study. In this context, pomegranate peels crude juice is a valuable source of health-promoting compounds, fulfilling concurrently the promising antioxidant activity that can be utilized virtually as food complements, to delay lipid oxidation and healing from particular ailments via its free radicals scavenging ability.

  • Time :

Abstract:

This study analyses i) the potential application of fish oil microcapsules made of lecithin + maltodextrin (monolayered, Mo) and lecithin + chitosan‐maltodextrin (multi‐layered, Mu) as vehicles of eicosapentaenoic (C20:3 n‐3, EPA) and docosahexaenoic (C22:6 n‐3, DHA) acids in cooked (C‐SAU) and dry‐cured (D‐SAU) meat products and ii) the bioaccesiblity of these fatty acids. Both, Mo and Mu achieved the enrichment in EPA and DHA without influencing on the lipid composition of the enriched products. The quantity of fatty acid released at the different phases of the in vitro digestion of meat products added with microcapsules has been firstly described in the present study. The addition of fish oil microcapsules did not affect the release of fat and fatty acids of the meat products, but it influenced on the bioaccesibility of EPA and DHA. Moreover, the type meat matrix seems to be a significant effect on the released of fat and fatty acids. In this way, the addition of fish oil microcapsules of lecithin + chitosan‐maltodextrin as wall material to cooked sausages should be more appropriate than fish oil microcapsules of lecithin + maltodextrin and dry‐cured sausages to maximize the percentage of EPA and DHA available for absorption. Therefore, it could be pointed out the importance of analysing not only the quantity of EPA and DHA in the enriched foods, but also the bioavailability of these bioactive compounds in most of the possible products. These could be used to develop functional foods that provide healthier lipid profiles and promote health and welfare.

  • Time :

Abstract:

Background: Malnutrition is frequent in older people and a precursor for morbidity and hospitalisation; furthermore low intake and weight loss during and after hospitalisation is well-described. Such patients are often excluded from technology projects on account of lack of skills. This is a barrier for their access to many current and future health care offers. Objectives: To test the acceptability, feasibility and preliminary efficacy of technology-supported energy-and protein-enforced homedelivered meals for older patients discharged from hospital. Design: Mixed method design including a quasi-experimental controlled feasibility trial and embedded qualitative interviews. Participants: Older medical patients (mean age 79.4 years; women 66.7%) at nutri-tional risk and discharged to own home were included consecutively to first the control group (n = 18) and later the intervention group (n = 18). Nine intervention and 16 control group patients completed the project. Methods: Intervention group received: 1) enriched meals delivered to participants’ homes 12 weeks after discharge, and 2) a tablet computer combining goal setting for intake with self-monitoring and feedback. Control group were treated as usual. Data collection was done at baseline, and at six and 12 weeks follow-up. Feasibility evaluation focused on 1) inclusion and retention and 2) acceptability and functionality of the intervention. Efficacy primary endpoint: Muscle strength and BMI. Secondary: Health related quality of life (HRQoL), depression; readmissions, mortality. Results: Technology challenges were related to immaturity of the out-of hospital app version; however, participants were motivated and capable of using the device. Inclusion and retention was challenged by the acceptability of the nutritional intervention and exhaustion among patients. Mortality was high. Although weaker at baseline the intervention group increased their muscle strength more consistently than did the control group: Handgrip strength with 2.5 kg vs 0.9 kg and chairto-stand-test with 3.3 vs. 1.8 times. They also improved their depression score and HRQoL more, and patients reported increased intake, appetite, and energy in the interviews. Relatives confirmed this and also reported positive impact on their level of worry and on the relationship with the older person. Conclusion: The study provided valuable insight into appropriate methods and procedures as well as older people’s preferences and views on barriers to successful intervention and use of technology in health care. This will guide the design of a future sufficiently powered study.

  • Time :

Abstract:

To ensure products meet the highest standards, the global infant formula industry works to ensure a thorough understanding of the capability of an analytical method (that is the ability of a method to produce test results within the regulatory limits) as an additional key parameter when establishing compositional criteria for nutrients in infant formula. All analytical test methods have some uncertainty. The key factor is understanding method variability in the context of overall variability, which also includes variation in raw materials/ingredients and the manufacturing process. The overall variability must fit within the regulatory limits. By using existing performance data of recently established international Official Methods/Standards it was shown that for products with a manufacturing target at the midpoint of regulations, the probability of obtaining an analytical result outside the regulatory requirements due to analytical variation of the method alone can be as high as 19%. This can cause legal uncertainties. This work supports a risk management approach that takes into consideration the analytical method capability when establishing regulatory limits for nutrients in infant formulas.

  • Title:Assessment of Water Quality Index and Study of the Impact of Pollution on the Rivers of Kerala
  • Time :

Abstract:

Pollution of water bodies will have dire consequences on an already water stressed country like India. Multiple parameters like pH, hardness, dissolved solids, dissolved oxygen, biochemical oxygen demand etc. are measured to assess water quality. However, it is difficult for a layman to understand the significance of the various parameters being monitored by the Pollution Control Board. Water Quality Index, which encompasses the impact of these physical and chemical parameters on the quality of a water sample, can be used as an effective tool to convert convoluted parameters into a more comprehensible form. This study develops a generalized and reliable C language code to quickly compute the Water Quality Index for different water bodies. The Water Quality Index is calculated, using the code, for some of the rivers in key geographic locations of Kerala. It has been found that most of the rivers in the central part of Kerala like rivers Periyar and Muvattupuzha are of poor water quality, while most of the rivers in the southern part of Kerala are of good water quality. Some of the rivers in northern part of Kerala like rivers Kadalundi have good water quality, while rivers like Chaliyar have poorer water quality. The comparison of two models for calculating the Water Quality Index is also presented.

  • Title: Agricultural and Supply Chain Impacts of the Pandemic, with Special Emphasis on the Dairy Sector
  • Time :

Abstract:

Food supply chains in North America have become remarkably efficient, supplying an unprecedented variety of items at a low cost. The initial stages of the COVID-19 pandemic and the severe restrictions on dining outside the home exposed the risk of a system that assumes predictable sales and highly reliable transportation systems. Despite early fears and disruptions, the food sector, from farm to retailer, has proven to be quite resilient in total, although there is a huge range of impacts on specific businesses. In the main, agricultural production for major commodities continued uninterrupted. Food processors maintained their output and adapted to a very different distribution opportunity. Consumers had no problem finding food, although there may have been disruptions in certain items at any point in time. A common theme in assessing the impacts across the six major food categories that were examined is the growing importance of understanding the whole supply chain. An important but as yet unresolved question is whether the pandemic experience results in a fundamental reassessment of supply chain vulnerabilities and risks that will cause changes in operating practices and strategies. Enhanced and more aggressive protocols related to worker health seem most likely. Insofar as current systems have tended toward a rather high degree of specialization in production and sales, another example might be greater consolidation of firms, diversification of products, and a greater diversity of customers. At the end of the supply chain there are questions about lasting changes in consumer food buying behavior, including more online shopping for basic foods, meal kits, or prepared meals. There might also be heightened interest in shorter supply chains and more local food systems. It is too early to safely anticipate the answers to these questions, but industry surveys and past behavior would suggest that this experience will have some lasting effects and consumer responses will be especially important in driving behavior.

  • Title:Better Fatty Acids Profile in Fillets of Nile Tilapia (Oreochromis Nloticus) Supplemented with Fish Oil
  • Time :

Abstract:

Fish is an important source of high-quality; readily digested protein in the human diet, a rich source of minerals and vitamins, and it contains lipids that are recognized as having high nutritional value. Tilapia has become the most popular aquaculture product in the world; with the Nile tilapia (Oreochromis niloticus) considered the most desirable species. The fatty acid (FA) composition of freshwater fish is characterized by high levels of n-6 PUFAs, mainly linoleic acid (C18:2n-6). In contrast, marine plankton and the fish that feed on them present low levels of n-6 PUFAs and a predominance of eicosapentaenoic acid (EPA, C20:5n-3) and docosahexaenoic acid (DHA, C22:6n-3). Marine fish oil is rich in n-3 long-chain PUFAs (LC-PUFAs). Polyunsaturated fatty acids (PUFAs) are biologically important compounds that confer protection against diseases, including cardiovascular diseases and rheumatoid arthritis. They also display anticarcinogenic properties and support the immune system and brain functions. Dietary supplementation with marine fish oil tends to increase the concentration of n-3 LC-PUFAs in the muscular tissue of the freshwater fish. An increase in levels of the n-3 series of FAs was observed in tilapia fillets that were supplemented. Modern human diets have ratios of n-6/n-3 ranging from 15:1 to 20:1, in contrast to an ideal range of 1:1 to 4:1. The high concentration of EPA and DHA in the fish oil was reflected in nutritionally satisfactory ratios of n-6/n-3 in tilapia fillets. Using a good marketing strategy it is possible to add economic value to the fillet making improved profitability.

  • Title:Sustainability Indicators for Sustainably-Farmed Fish
  • Time :

Abstract:

To be sustainable, farmed fish should be environmentally suitable, biologically ideal, socially acceptable and economically viable. As these sustainability indicators (SIs) strongly influence consumers’ fish pur- chase intent, farms should report them as a balanced source of sustainability information. However, in the literature, little attention has been paid to biological indicators in assessing aquaculture sustainabil- ity, nor to the extent of the SIs. Furthermore, the assessed SIs have not been examined by consumers. Therefore, this study measures consumers’ perceived value of these. Consumers’ sustainability knowl- edge and attitude towards farm-raised fish are also taken into account. Multinomial logit and basic latent class logit models are employed, together with a direct survey of households in Bangladesh. The results demonstrate that a low level of water use and appropriate feeding in the production process (e.g., environmental and biological indicators) of farmed fish increase consumers’ utility and that they are willing to pay a price premium for these attributes. Consumers look for the ‘safety label’, which indicates inter-mediately, averagely, and fairly sustainable farmed fish. Initially, consumers prefer averagely sustainable fish, but when they eat a high amount of farmed fish in their total fish consumption, they are more likely to prefer fairly sustainable ones, which are high sustainable. Therefore, the study results indicate that produced fish should be marketed with environmental and biological sustainability indicators, including food safety labels. Additionally, a close monitoring system will increase social acceptability, leading to sustainable fish farming and consumption.

  • Title:Assessment of Productivity and Profitability of Wheat Using Nutrient Expert® -Wheat Model in Jhapa District of Nepal
  • Time :

Abstract:

Wheat is the third most important cereal crop in Nepal after rice and maize both in area and production, but its productivity of 2.3 tonne ha−1 is very less compared to other developed countries (6 tonne ha−1 for Switzerland and China) in the world. The main cause of low wheat yield in Nepal is the improper and inadequate use of fertilizer devoid of site specific nutrient management practices. Therefore, a farmers’ field experiment was conducted during November 2015 to April 2016 to rectify the best fertilizer management options at two sites of Damak and Gauradaha in Jhapa district in eastern-Terai of Nepal using Nutrient Expert®-Wheat model. The research was accomplished in Randomized Complete Block Design with 2 treatments and 20 replications, considering farmers’ field as replication. Two treatments included in the experimentation were NE® (Nutrient Expert Recommendation) and FFP (Farmer’s Fertilizer Practices). The statistical result revealed the highly significant difference in terms of number of effective tiller m−2, plant height, filled grain per spike, spike length, grain, straw and biological yields and harvest index. The highest yield (4.71 tonne ha−1) was obtained from NE field than FFP (2.99 tonne ha−1). On an average, NE based practices produced 58 % higher yield in comparison to FFP. NE based treatment produced significantly higher biomass yield, yield attributes and cost-benefit ratio than FFP treatments. Field experiment validation confirmed that the Nutrient Expert® Wheat model could be used as the most adoptable and practical precision decision support system tool to make a more authentic fertilizer recommendation in eastern-Terai of Nepal.

  • Title:Nutritional and Functional Properties of Some Local Cultivars of Moringa Oleifera
  • Time :

Abstract:

This study was carried out to evaluate the nutrient composition and functional properties of dried Moringa oleifera leaves collected from two different ecological zones in Bangladesh, Joypurhat and Mymensingh. The proximate analysis revealed that M. oleifera leaves were rich in protein content, ranging from (22.99 to 29.36%), and low in fat, from (4.03 to 9.51%), fiber, from (6.00 to 9.60%), and ash, from (8.05 to 10.38%). The vitamin C content of fresh M. oleifera leaves ranged from (187.96 to 278.50 mg/100 g), Ca ranged from (1.322 to 2.645%), P ranged from (0.152 to 0.304 g/100 g), and K ranged from (1.317 to 2.025 g/100g). The functional properties included WAC (158.00-415.00%), FC (28.30-117.65 ml/l,) and FS (333.33-1000 ml/l). Together, these findings indicate that M. oleifera leaves are rich in vital phytonutrients, suggesting a promising balance of food ingredients for human and animal diets.

  • Title:Lipidome Changes, with A Focus on Phospholipids, Due to Feeding Systems and Processing in Goat Milk
  • Time :

Abstract:

We evaluated the effects of processing – pasteurization and yoghurt manufacturing – on some health-promoting lipidome components in milk from two feeding treatments – brushland grazing or hay-feeding in confinement – in dairy goats. The contents of fat and protein were higher, and of urea, lower, in grazing goats. Fatty acid composition – at the exception of saturated fatty acids – was affected by dietary management and milk processing. Phospholipid contents was lower in confined goats, with little effect for processing. The phospholipid-totriglyceride ratio was decreased by pasteurization. Sensitivity to pasteurization of phospholipid composition differed between feeding treatments. The percentage of sphingomyelin increased following pasteurization, with no response for fermentation to yoghurt. These results can be exploited to modulate health-promoting fats in dairy products.

  • Title:Chemometric Approach in Monitoring the Generation of Volatile Compounds in Model Milk Systems with Low-Frequency Ultrasound
  • Time :

Abstract:

The application of low-frequency ultrasound in dairy processing offer prominent benefits in improving the functionality of milk and dairy products, as well as the dairy processing efficiency. However, chemical and physical effects from ultrasound can cause the generation of undesirable volatile compounds which may result in off-flavours. The underlying research investigated the volatile profile in sonicated model milk systems with different ratios of caseins, whey proteins and fat using chromatography. Furthermore, the corresponding changes in milk components as affected by ultrasound were monitored via Infrared spectroscopy. Low- frequency ultrasound were performed at 20 kHz up to 10 min. The volatile compounds including hydrocarbons, esters, aldehydes, ketones, and alcohols which appeared to be the products of lipid oxidation and protein degradation were characterised in sonicated milk. Chemometric analysis showed that the fat content and the variation of milk proteins (caseins and whey proteins) had negligible effects on the generation of volatile compounds, whereas sonication time significantly influenced the intensities of volatiles produced in sonicated milk systems. The application of ultrasound for a short period less than 5 min were recommended to minimise the formation of undesirable volatile compounds. The research findings will add valuable insights into the volatile profiles and advance the application of low-frequency ultrasound within the dairy industry.

  • Title:Exopolysaccharide-Based Edible Coating and Lactic Acid Bacteria with Antifungal Activity Preserved the Postharvest Quality of Cherry Tomato
  • Time :

Abstract:

One of the main causes of cherry tomato postharvest loss are diseases caused by food-contaminating fungi. Currently, the use of fungicides is the main strategy to control the contamination caused by different types of fungi, but these treatments can cause side effects such as environmental contamination, impacts on human health, and the development of resistance by pathogenic strains, which have generated the need to develop new alternatives to replace the use of synthetic chemicals. Edible coatings (ECs) can preserve the quality of this crop and can serve as carriers of lactic acid bacteria (LAB), which have demonstrated inhibitory potential against phytopathogenic fungi. The effectiveness of the LAB strain Lactiplantibacillus plantarum A6 incorporated into an EC based on exopolysaccharide from Weissella confusa JCA4 on the physicochemical and microbiological quality of cherry tomato was evaluated.The fruit were artificially inoculated with the fungi Aspergillus niger, Fusarium sp., and Rhizopus stolonifer to test the antifungal potential of the coating. The physicochemical and microbiological quality of cherry tomato was studied at two storage temperatures to calculate its shelf life.
L. plantarum A6 remained viable both in the solution and on the surface of the fruit after coating, protecting the fruit against two of the three evaluated fungi (Fusarium sp. and Rhizopus stolonifer). The EC controlled weight loss, maintained firmness, and slowed the respiration rate of cherry tomato; the other physicochemical properties and the appearance of the fruit were not negatively affected. EPS composite coating containing L. plantarum A6 as antifungal agent could be a promising industrial treatment to control fungal deterioration and maintain the postharvest quality of tomatoes.

  • Title:High Temperature Triggers the Antioxidant Action of Two Two Edible Isothiocyanates: Sulforaphane and Erucin. Effect of Sulfenic Acids and Methylsulfinyl Radicals as Radical Trapping Antioxidants
  • Time :

Abstract:

Sulforaphane (SFN) and erucin (ERN) are isothiocyanates (ITCs) bearing, respectively, methylsulfinyl and methylsulfanyl groups. Their chemopreventive and anticancer activity is attributed to ability to modulate cellular redox status due to induction of Phase 2 cytoprotective enzymes (indirect antioxidant action) but many attempts to connect the bioactivity of ITCs with their radical trapping activity failed. Both ITCs are evolved from their glucosinolates during food processing of Cruciferous vegetables, therefore, we studied antioxidant behaviour of SFN/ERN at elevated temperature in two lipid systems. Neither ERN nor SFN inhibit the oxidation of bulk linolenic acid (below 100C) but both ITCs increase oxidative stability of soy lecithin (above 150C). On the basis of GCMS analysis we verified our preliminary hypothesis [1] about participation of sulfenic acids and methylsulfinyl radicals as radical trapping agents responsible for the antioxidant effect of edible ITCs during thermal oxidation of lipids at elevated temperatures (above 140C).[2]

  • Title:Development and Application of Biodegradable Packaging by Blown Extrusion
  • Time :

Abstract:

Most of food packaging is mainly petroleum based, trhough plastic precisely. These plastics bring many benefits such as protection, transportation and increasing the shelf life of food. Thus, plastic gained popularity over the years increasing its production and becoming the standard for food packaging. However, there are increasing concerns about its usage and the disposal due to the accumulation in natural habits.This lecture will discus the production of biodegradable food packaging using the same technologies as for plastic packaging, particularly we will discuss blown extrusion. It will contrast the laboratory production (casting technique) vs. extrusion and offer a comparison from a point of view of mechanical properties of the packaging. As applications, it will focus on fruit and vegetables.

  • Title:Formulation of Natural Hydrocolloids and Virgin Coconut Oil as Plant-Based Salad Dressing
  • Time :

Abstract:

Salad dressing is traditionally used as a seasoning to enhance the appetite of consumers due to its creamy mouthfeel and special flavour. Consumers are aware about the cholesterol level in egg yolk and fat’s type applied in dressing products. The aim of this study was to produce low fat and eggless salad dressing with virgin coconut oil (VCO). Hydrocolloids included xanthan gum and modified starch were use as independent variables by response surface methodology (RSM) in order to evaluate its impacts on the viscosity, stability, and firmness of the salad dressing. The findings showed that optimum values for the hydrocolloids of xanthan gum and modified starch were 1.56% and 0.10%, respectively and the optimum experimental values were stability 0.33%, texture 1506.5 g, and viscosity 162.25 mpas. The predicted and experimental data of this optimized formulation had no significant (p>0.05) differences which indicated the desired results from this study. The proximate analysis of the optimized formulation were moisture content 47.91, ash 1.91, fibre 1.57, fat 21.97, protein 1.66, carbohydrate 24.98, and caloric values 296.29. The findings of this study were similar to the commercial products which suggested high potential for using optimum values for the hydrocolloids of xanthan gum and modified starch as egg replacer and VCO in salad dressing to improve the quality and the biological functions of the product.
