  • Title:Nutrient contents and anti-hyperglycemic effects of the immature endosperm of sugar palm (Borassus flabellifer) fruit on patients with type 2 diabetes mellitus
  • 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levels returned within normal range by the end of the sixth week and also maintained the normal FBG levels even after withdrawn of the feeding of IESP.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.

  • Title:Importance of Microbiological Media in Microbiological Control of Food
  • Time :

Abstract:

Foodborne diseases interfere with the socio-economic development of society, burdening the health system and damaging the national economy, tourism and trade. The globalization of food production and trade makes the food chain longer, complicating investigations into diseases caused by food poisoning by delaying the possibility of emergency intervention at the site of the problem. The health safety of food, its nutritional value and food safety are inextricably linked. That is important for the advisory and coordinating role of public health institutions in the implementation of health assessments of human health hazards.
Laboratory for preparation of microbiological media (MM) occupies an important role in quality assurance of microbiological results in bacteriological diagnosis. The laboratory is qualified according to the requirements of ISO/IEC 17025 and maintaining the status of accredited laboratory requires continuous care for the qualifications of laboratory and the quality of work performed. Some requirements are: the process of systematically kept records documents, the technical competence of laboratories, the accuracy and reliability of microbiological test results. All this is to ensure quality services in microbiology with parasitology, there by increasing productivity of bacteriological tests and thus the whole system of microbial activity.
It is important for each laboratory to ensure the quality of the results of the measurements, which are carried out using the quality management system. The implementation of risk analysis and activity plan in routine work provides an indicator of the justification of investments in occupational safety measures, ie in preventive and / or corrective measures, all in order to reduce the risk to an acceptable measure.

  • Title:Effects of the process parameters on container filling
  • Time :

Abstract:
The filling of a container with a free surface jet is an important step in many industries, such as the pharmaceutical or food industries. This process consists in delivering a given quantity of material in the shortest possible time. One of the challenges is to control the flow pattern to avoid overdosing, inclusion of air bubbles or the absence of flatness of the deposit’s free surface. This problem is even more accurate for semi-solid fluids, also known as yield stress fluid or viscoplastic fluids, which generate specific flow forms, particularly in relation to the presence of a yield stress.
In this paper, we propose to identify the different patterns, their characteristics and the effects of process parameters like the average velocity in the injection nozzle, the height between the nozzle and the bottom of the container, called “dosing height”, the nozzle diameter, the average velocity, the injected volume and the container width. These process parameters are the main ways to control industrial processes, since they are adaptable for a given material.
For this purpose, an experimental approach where the injection flows are visualized with a model yields stress fluid. The fluids used allow modulating the rheological properties of semi-solid products, such as yield stress, viscosity and shear-thinning. In addition, the experimental observations are compared to the numerical modelling of these flows by implementing an anelastic Hershel-Bulkley behavior to represent the rheological parameters.
The results show the main effects at work in the conditioning process, such as inertial, viscous, plastic and gravity. The flow patterns as well as the mapping of transitions between them are discussed in terms of the previously mentioned process parameters. The transitions are discussed in terms of the conservation of the mechanical energy of the jet and dimensionless numbers evaluating the ratio of the forces governing the physical phenomenon.

  • Title:A novel approach in sugarcane juice processing
  • Time :

Abstract:

Sugarcane juice is a nutritious, energetic and popular drink in Brazil. For its processing, the
use of supercritical carbon dioxide (SC-CO2) technology as an intervention potentially capable
of rendering high quality products can be considered. This study was undertaken to evaluate
the impact of mild temperatures combined with SC-CO2 on the physicochemical parameters,
color, enzymic inactivation, and microbial reduction in cane juice. Pressures (P) in the range
of 74 to 351 bar, temperatures (T) between 33 and 67 ºC, and dwell times (t) varying from 20
to 70 min were tested in a central composite rotatable design. Seventeen trials were performed.
The pH and soluble solids in the raw cane juice ranged widely (pH 4.6–6.0 / 17.3–25.3 ºBrix).
In the processed juice, variations were 4.4–6.6 and 17.2–25.0 ºBrix. The total color difference
(TCD) between raw and processed juice varied from 2.3 and 12.3. The percentages of
polyphenol oxidase (PPO) and peroxidase (POD) reduction ranged from 1.7 to 74.3%, and
between 0.3 and 51.2, respectively. The log reduction of mesophiles, molds and yeasts, and
lactic bacteria varied from (0 to 4), (0.2 to 3.7) and (0 to 1.9), respectively. Salmonella spp.
counts in the raw juice reached 2.2 logCFU/mL, and it was not detected in the processed juice.
As for the thermotolerant coliforms, counts attained 5.2 logCFU/mL, and log reductions varied
from 0.3 and 2.5. The analysis of effects (p ≤ 0.1) pointed out that the interaction between T
and t (T/t) had a significant effect on mesophiles, molds and yeasts log reduction, pH variation,
and PPO reduction. As for the lactic bacteria reduction, T, P/t and T/t played a significant
effect. P, T, t and T/t had a significant effect on the TDC. The combination of mild temperatures
and SC-CO2 can be potentially used for cane juice preservation.

  • Title:Microbiota profile analysis of the Mediterranean mussel (Mytilus galloprovincialis) from Northern Aegean Sea (Greece) culture areas, based on a 16SrDNA Next Generation Sequencing approach.
  • Time :

Abstract:

Mediterranean mussels (Mytilus galloprovincialis) (Lamarck, 1819), due to their nutritional mechanisms which involve filtering huge amounts of water, are affected by seawater pollution and can host microbial diversity of environmental origin as well as pathogenic bacteria, which must be constantly monitored. In this study, we applied a Next Generation Sequencing marker gene (16SrDNA) approach for the characterization of the M. galloprovincialis microbiota, collected from mussel farms in the region of Thermaikos gulf, Northern Aegean Sea, Greece. The collection of samples was carried out during the winter months (December 2021 – February 2022), in specific farm zones (Chalastra, Makrigialos), by the official Veterinary service following the appropriate protocol. Totally twelve samples were collected from a 3-8 meters depth, where the temperature was also measured, and within four hours they were transferred to the Veterinary Center of Thessaloniki. 10-12 mussels were selected from each sample and the selected ones had to be alive, adult and of similar size. Then, their shell was opened with a sterile knife, the content (flesh and liquid) was placed in stomacher bags and homogenized for 2 minutes, using the Stomacher device. A microbiological test was also performed using the Most Probable Number (MPN) method for the enumeration of Escherichia coli (according to ISO 16649-3: 2005) and the presence of Salmonella sp. (isolation method using RVS broth and XLD agar). DNA isolation with the DNeasy PowerFood Microbial Kit and amplification of whole 16SrRNA gene ( ̴1500 bp) was conducted with locus specific primers (27F & 1492R), where each sample was marked with a different barcode. Libraries were constructed according to the 16S barcoding kit (Oxford Nanopore Technologies), after pooling all barcodes, for targeted amplicon sequencing. Raw data were base called with algorithms implemented in GUPPY software (Oxford Nanopore Technologies), where reads were demultiplexed according to the used barcodes. Clean sequences were obtained after trimming of barcodes, adapter and primer sequences. Subsequently, they were subjected to EPI2ME Fastq 16S cloud-based bioinformatics workflow (Oxford Nanopore Technologies) for taxonomic classification. The results obtained, showed statistically significant differences between the two sampling regions. More specific, in Makrigialos region the five most abundant genera were Anaplasma (20.9%), Mycoplasma (7.6%), Polaribacter (3.1%), Ruegeria (2.5%) and Rubritalea (1.7%), whereas in Chalastra region the respective ones were Mycoplasma (10.6%), Pseudomonas (3.7%), Mariniblastus (3.4%), Legionella (2.9%) and Rubritalea (2.2%). We hypothesize that different environments generate conditions for specific microorganism growth, reducing competition and favoring the selection of certain genera.

  • Title:Molecular characterization of the bacterial communities present in sheep's milk and cheese produced in South Brazilian Region via 16S rRNA gene metabarcoding sequencing
  • Time :

Abstract:

Sheep’s milk and cheese represent unexplored reservoirs of microorganisms’ genetic and metabolic diversity. This study aimed to characterize the microbial communities of milk and cheese from sheep of Lacaune breed, produced in the South Region of Brazil. Milk samples (n = 15) from three dairy farms and four types of cheese (fresh, colonial, feta-type, and pecorino-type; n = 20) were subjected to partial 16S rRNA gene sequencing. Streptococcus spp. and Lactobacillus spp. were the dominant taxa (core microbiota) of cheeses, while Phyllobacterium spp. and Staphylococcus spp. were the most prevalent genera in milk. Regarding milk samples, no differences in alpha diversity were observed between the analyzed farms. However, beta diversity analysis revealed that milk collected on Farm 1 differed from the others. These differences may be associated with sheep feeding, mammary gland diseases, and the milking practices used. Upon analyzing cheese samples, significant differences in both alpha and beta diversities were observed between the different cheese types, suggesting that processing and maturation conditions are important for shaping cheese microbiota. Notably, other bacterial groups including decomposers and potentially pathogenic microorganisms to humans were observed in some of the analyzed cheeses. This study expands our knowledge of the bacterial composition of sheep’s milk and cheese found in different geographic regions.

  • Title:Assessment of Mycotoxin Contamination in Peanut- and Corn-Based Products Consumed in São Paulo, Brazil
  • Time :

Abstract:

In this work, a previously validated analytical methodology was applied for the simultaneous determination of 11 mycotoxins (aflatoxins [AF] B1, B2, G1 and G2, fumonisins [F] B1 and B2, ochratoxin A (OTA), zearalenone (ZEA), T-2 toxin, HT-2 toxin and deoxynivalenol (DON) in food products (peanuts, corn and derivatives) collected in supermarkets in the region of Pirassununga, São Paulo, Brazil. Analyses were performed by liquid chromatography coupled with mass spectrometry (LC-MS/MS), using isotopic standards of mycotoxins. Analytical standards from AFB1, AFB2, AFG1, AFG2, FB1, FB2, OTA, DON, T-2, HT-2 and ZEA (Sigma-Aldrich, Brazil) were used, as well as isotopically labeled standards [13C17]-AFB1, [13C34]-FB1, [13C20]-OTA, [13C18]-ZEA and [13C15]-DON (Romer Labs, Austria), available in the laboratory. Among 61 samples analyzed, 32 had detectable concentrations of at least one mycotoxin, and among the 11 mycotoxins studied, 5 were detected, namely: AFB1, FB1, FB2, ZEA, T-2 and HT-2 toxins. However, only corn kernel samples exceeded the tolerance limit established by Brazilian regulations. The probable daily intake (PDI) for corn products exceeded the values of tolerable daily intake (TDI) for FB1 and FB2 of 2.0 μg/kg bw/day established by the World Health Organization (WHO), indicating that there is a possibility of significant risk to Brazilian public health arising from exposure to the mycotoxins studied. This survey indicated that the occurrence of fumonisins in corn-based products sold in the region of Pirassununga is high, highlighting the importance of preventive actions to avoid risks to consumers, as well as the need for specific legislation and prevention of fungal development in all the product manufacturing steps, as well as during the harvesting and storage of the grain. The higher PDI value for fumonisins than the TDI in most corn-based products warrants concern on the possible health risks related to consumption of these types of foods by the population in the studied area.

  • Title:Diabetogenic impact of exosomal microRNAs of pasteurized cow milk
  • Time :

Abstract:

Consumption of pasteurized cow milk is a novel behavior of humans. Pasteurization of milk, a
gentle thermal processing, was introduced with the intention to reduce pathogenic bacterial
growth butto protect valuable bioactive ingredients of milk. In contrast to ultraheat treatment
(UHT), pasteurization protects bovine milk exosomes (MEX) and their bioactive microRNA
(miR) cargo. Translational evidence implicates that human MEX miRs promote pancreatic
beta-cell growth and mTORC1 activation associated with reduced glucose-stimulated insulin
secretion (GSIS). Human MEX miR signaling terminates after weaning associated with a
decrease in mTORC1 and increase in AMPK activity enhancing GSIS. There is critical concern
that continued intake of bovine MEX miRs promote beta-cell de-differentiation back to the
postnatal state thereby enhancing beta-cell endoplasmic reticulum stress with apoptosis
resulting in type 2 diabetes mellitus. MEX miRs of cow milk are a health hazard and have to
be eliminated from the human food chain.

  • Title:Structural and physicochemical properties of resistant starch from Korean rice cultivars
  • Time :

Abstract:

Resistant starch (RS) is not hydrolyzed into D-glucose in the small intestine and ferments in the large intestine. Rice (Oryza sativa L.) is a major source of carbohydrates and plays an important role in providing energy to the body. The purposes of this research were to elucidate the starch characteristics of different amylose contents in various rice cultivars developed by the National Institute of Crop Science and enhance use of resistant starch (RS)-containing “dodamssal” (DDS) rice as a health-promoting low-glycemic-index (GI) food.
Non-digestible starches (NDS) and native starches (NS) were isolated from four rice cultivars: Baegokchal (BOC), Ilmi (IM), Mimyeon (MM), and DDS. MM- and DDS-derived NS showed high amylose and low rapidly digestible starch contents as well as high slowly digestible starch and RS proportions. The BOC, IM, and MM starch crystals showed A-type X-ray diffractometry patterns. However, the DDS granules displayed a C-type crystallinity pattern with a predominant B-type and convex spherical shape. All the IM and BOC starches were hydrolyzed, with no remaining NDS residues. MM and DDS NDS showed longer average amylopectin chain length but lower molecular weight and viscosity than the NS. The DDS starch had the lowest digestibility and highest RS content, showing its potential to fight obesity and hyperglycemia.

  • Title:Ohmic heating pretreatment to produce black garlic
  • Time :

Abstract:

The consumption of black garlic (BG) has been attributed to various biological functions with benefits to human health; such as antioxidant, anti-allergic, anti-diabetic, anti-inflammatory and anti-carcinogenic effects. BG is a product derived from the thermal process of fresh garlic, reducing its characteristic pungent odor and taste considerably due to the organosulfur compounds that fresh garlic has. Common processing to obtain BG is carried out under controlled conditions of high temperature (60 – 90°C) and relative humidity (55 – 90%) where the Maillard reaction is promoted. The necessary period to obtain a quality product can vary from 30 to 90 days, depending on the variety of bulb, size, content of fructans and reducing sugars. One of the alternatives to reduce the process time is applying ohmic heating (OH) as pre-treatment; this causes the hydrolysis of fructans, obtaining free fructose, a reducing sugar that is degraded during storage in conditions of 70°C/94% RH through the Maillard reaction, accelerating the formation of compounds responsible for the flavor and color of garlic black, compared to black garlic without pretreatment. The characteristic color of black garlic from bulbs treated with ohmic heating (OH-BG) was obtained in 12 days; while in untreated bulbs (CT-BG) 30 days were needed. The content of 5-hydroxymethyl-2-furaldehyde (HMF) was 3.6 times higher in OH-BG than in CT-BG. Polyphenol content and antioxidant capacity did not show statistical differences between CT-BG and OH-BG, but their levels were higher than a commercial sample. Both products (OH-BG and CT-BG) presented high °Brix values (36.8 and 31.6 °Bx, respectively) which are perceived as sweet taste, and also have a chewy consistency and pleasant aroma, achieving excellent sensory acceptance. These results highlight the potential of ohmic heating pretreatment in reducing the time to obtain good quality BG.

  • Time :

Abstract:

Orange sweetpotato has been used as a source of betacarotene in different countries and more recently, in Brazil. Brazilians are used to consume sweetpotato roots with white flesh, purple or white skin and high dry matter content. The initial introduction of cultivars with traits different from the usual, showed to be a challenge in some Brazilian regions. This work will present the efforts required to identify alternatives to introduce the consumption of orange flesh sweetpotatoes on the Brazilian diet. The work started in 2008 and included initiatives on food processing, to enable better acceptance by consumers. Additionally, it also included the development of new cultivars that met the minimum growers’ agronomic requirements and also good nutritional characteristics. These efforts included experiments in different municipalities to assure the stability of the sweetpotato genotype selected. In 2021 a new sweetpotato genotype was released and promise to collaborate even more with the expansion of the biofortification program in the country. This initiative was only successful due to the development of a very broad and committed network that included producers, consumers, public and private companies and universities.

Abstract:

Objective
Recent researches suggest that there is a relationship between the pathogenesis of depression and serum Brain Derived Neurotrophic Factor (BDNF) levels. Therefore, the purpose of this clinical trial was to determine effect of magnesium supplementation on serum Level of BDNF, magnesium and depression status in patients with depression.

Methods
A double blind randomized clinical trial was conducted on 46 depressed subjects. The participants were randomly allocated into the magnesium (MG) and the placebo (PG) group and received 500 mg magnesium and placebo daily for 8 weeks. Beck’s test was conducted and blood samples were taken at baseline and after the intervention period for analysis of serum magnesium and BDNF.

Results
No significant differences were observed in assessed variables between the two groups at the baseline. At the end of intervention, supplementation with magnesium oxide had a significant effect on Beck’s test (P = 0.01) and serum magnesium (P = 0.001), but had no significant effect on BDNF levels (P = 0.507) between the two groups.

Conclusions
Daily intake of 500 mg magnesium oxide for at least 8 weeks improved Beck’s test score and serum magnesium in depressed patients, but had no significant effect on BDNF levels between the two groups, Which Further research is recommended.
Keywords: BDNF; Beck’s test; Brain derived neurotrophic factor; Depression; Magnesium; Randomized clinical trial.

  • 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.

Biography:
Dr Malcolm McPhee began working for NSW Department of Primary Industries in November 1991 at the Elizabeth Macarthur Agricultural Institute within the Nutrition and Physiology Laboratory, Camden, Australia. He was transferred to Armidale, NSW, Australia in 1997 to work within the Beef Industry Centre of Excellence and on projects within the Beef Cooperative Research Centre. Dr McPhee’s research is focussed on assisting beef producers ‘meet market specifications’ and improve productivity and profitability. Drawing on over nearly three decades of scientific research Dr McPhee has been instrumental in the development of 4 major decision support tools for sheep and cattle producers. More recently, Dr McPhee has worked with a team of scientists in the development of the BeefSpecs calculator (http://beefspecs.agriculture.nsw.gov.au/) and BeefSpecs drafting tool (http://beefspecs.agriculture.nsw.gov.au/drafting/). The work conducted on developing BeefSpecs has led to the development of 3D imaging technologies in collaboration with the University of Technology, Sydney, Australia with funding from Meat and Livestock Australia to objectively assess hip height, P8 fat, and muscle score on live cattle. Dr McPhee has a Bachelor of Applied Science in mathematics majoring in statistics from the University of Technology, Sydney, Australia, Masters Degree in statistics from the University of Wollongong, Wollongong, Australia and a PhD in Nutritional Biology, majoring in Animal Systems modelling, from the University of California, Davis, California, USA. Dr McPhee is committed to developing technologies and decision support tools to improve the productivity and profitability of agricultural industries.
