title: Monitoring and risk assessment due to presence of metals and pesticides residues in honey samples from the major honey producing forest belts and different brands

description: Abstract Honey is consumed worldwide because of its nutritional, therapeutic and medicinal purposes. Generally it is perceived that honey reaches its consumer in pure form however this is not always true as contaminants can end up in honey. Thus this study was designed to check the presence of contaminants in honey samples. For this purpose 52 samples were collected from forest belts while 25 samples of national and international brands were purchased. Heavy metals zinc, iron, cobalt and copper were detected in all 52 samples collected from forest belts. In honey brand samples coper (25 samples), cobalt (detected in 12 samples) and chromium (2 samples) were detected above their permissible limits and THQ (Target Hazard Quotient) was also found exceeding 1 for two samples in which cobalt was detected. Lambda Cyhalothrin and bifenthrin were the only pesticides detected in few samples collected from forest belts while Imidacloropid, Difenaconazole, Glyphosate and bifenthrin were detected above their permissible limit in few national and international brands. Health risk index calculations showed that in 4 samples collected from forest belts and one sample of honey brand in which bifenthrin was detected, HRI exceeded its threshold value of 1 showing its potential to pose significant health risk.

title: Optimization of sunflower oil bleaching parameters: using Response Surface Methodology (RSM)

description: Abstract Bleaching is an important part of the oil refining process, in which pigments, impurities, traces of metals, and oxidative-molecular components of oils are removed. In this regard, the optimization of bleaching conditions can be effective to increase oil quality. In this study, de-gummed and neutralized sunflower oil was bleached at 80, 90, 100, 110, and 120 °C for 15, 25, 35, 45, and 55 min by acid-activated bleaching clay with the concentrations of 0.4, 0.6, 0.8, 1, and 1.2% under laboratory conditions. At that point, peroxide, anisidine, plus Totox values, free fatty acid content, Rancimat, and specific UV absorption at 232 and 270 nm were analyzed via the RSM method. The model optimization using the RSM method revealed that the optimal conditions were 37.31 min, temperature 92.7 °C, and clay concentration 1.18%; this circumstance can meet 86.7% of the expectations as could be met for reducing the factors effective for oxidization during bleaching.

title: Effects of heat treatments and edible shell coatings on egg quality after storage at room temperature

description: Abstract The objective of this study was to evaluate the effect of thermal treatments using different water temperatures and immersion times, as well as the application of eggshell coatings using edible materials on eggshell quality after storage for 4 weeks at room temperature (22.8 ± 4.4 °C). A total of 180 brown fresh eggs were distributed in a completely randomized design with six treatments and five replicates of six eggs each. The treatments consisted of a control group without any treatment (T1), three groups treated thermally: 56 °C/32 minutes (T2); 56 °C/20 minutes (T3); 56 °C/10 minutes (T4); and two groups with gelatin 2% (T5) and 5% NaCl solution (T6). After storage, it was found that the heat treatments at 56 °C for 10, 20 and 32 minutes provided maintenance of the albumen height, which reflected the values of the Haugh units but negatively influenced the albumen foam stability. The treatment with 5% NaCl solution showed the lowest lipid oxidation rate and the best albumen foam stability. The proposed treatments (thermal or coatings), individually, caused significant improvements on some eggs quality markers evaluated after 30 days of storage.

title: Effects of nitrogen supplementation on Saccharomyces cerevisiae JP14 fermentation for mead production

description: Abstract Honey must supplementation is necessary for mead production due to the deficiency in nitrogen materials in this feedstock, despite its high fermentative sugar content. The nitrogen limitation can halt or slow fermentation and lead to the production of unpleasant sensorial compounds, such as sulfur derivatives. The yeast JP14, a Saccharomyces cerevisiae isolated from Jataí bee’s pollen, was inoculated in 25 °Brix honey must with – 0 (control); 0,3; 0,7 and 1,0 g∙L-1 – of di-ammonium phosphate (DAP) and ammonium sulfate (AS). The addition of both supplements resulted in increased cell viability in the first 5 days of fermentation at 20 °C, but did not affect the final acidity of the produced meads. Supplementation also leads to increased sugar consumption, and sugar conversion into ethanol increased as nitrogen supplementation increased, especially with DAP. This indicates that these compounds also regulate yeast metabolic pathways. Supplementary nitrogen acts both in protein anabolism and the gene expression of glycolytic and fermentative pathway components, favoring, in this case, sugar conversion into ethanol. This is the first work describing how different DAP and AS concentrations influences mead production and showing the comparison between these two supplements.

title: Unsatisfactory microbiological aspects of UHT goat milk, soymilk and dairy beverage of goat milk and soy protein: A public health issue

description: Abstract Spore forming bacteria can play an important role in food quality and safety as spoilage and pathogenic microorganisms due to resistance to heat-treatment. However, there are limited number of studies focused on evaluate the microbiological quality and the occurrence of these bacteria in UHT goat milk, soymilk and dairy beverage of goat milk and soy protein. In this context, 75 samples of these beverages were evaluated regarding heterotrophic mesophilic microorganisms by conventional plate count and selective methods to detect microorganisms from Bacillus cereus group and Clostridium perfringens. Population counts greater than 104 CFU.ml-1 of heterotrophic mesophilic microorganisms were observed in 80% of the lots of goat milk and 100% of the lots of soymilk and dairy beverage of goat milk and soy protein. The presence of bacteria belonging to B. cereus group was observed in 16%, 52% and 44% of goat milk, soymilk and dairy beverage of goat milk and soy protein, respectively. C. perfringens was isolated from 8% samples of UHT soymilk. The frequency of genes hblA, hblB, hblC, nheA, nheB, nheC in 29 isolates obtained from these products was 62%, 48.2%, 96.5%, 79.3%, 68.9% and 79.3%, respectively. The microbiological quality of the evaluated products was unsatisfactory.

title: Characterization of hydrolysates of collagen from mechanically separated chicken meat residue

description: Abstract Obtaining collagen and hydrolysates from mechanically separated chicken meat residue is an excellent way to add value to this waste. The aims of this study were to obtain collagen hydrolysates from chicken MSM residue using Alcalase® and Flavourzyme® enzymes, as well characterizing the functional, structural and thermal stability properties. The highest degree of hydrolysis was obtained using Alcalase®, 36.11%, while using Flavourzyme® resulted in 12.02%. The DSC analysis of the collagen indicated a denaturation temperature of 46.47 °C. The FTIR spectra of the crude collagen showed absorption peaks that were characteristic of amide bands A, B, I, II and III. In the spectra of the hydrolysed the area of the amide bands was reduced, and some peaks appeared between 800 and 1,200 cm-1. The disappearance of high molecular weight bands in the SDS-PAGE analysis also confirmed the hydrolysis of collagen. After the hydrolysis, the collagen presented reduced viscosity, the capacity to form foam, and foam stability. The emulsifying activity index was high in the hydrolysates in relation to the crude collagen. Thus, the use of Alcalase® and Flavourzyme® to obtain hydrolysates from collagen derived from chicken MSM residue was shown to be viable, and potentially useful for industrial applications.

title: Promoters effectiveness in the improvement in iron and zinc absorption from the rice and bean

description: Abstract Iron and zinc are essential micronutrients for the organism functioning and their lack can result in prejudices to human health. The information about the presence of minerals in the diet are normally referred to its total concentrations, however these values do not reproduce the fraction that might be bioaccessible for the human body. The objective of this study was to evaluate if the promoters increase the iron and zinc bioaccessibility in a rice-and-bean mix. For this, four treatments were elaborated, all containing rice and bean and varied between each other regarding the promoters added to this mix. Ascorbic acid and cysteine were the promoters chosen to evaluate the influence in the iron and zinc absorption. For this purpose, the tomato was chosen to act as ascorbic acid source and garlic and onion were chosen to act as cysteine source. The treatments with tomato presented a higher rate of iron, significantly differing from those without tomato in their composition. Treatment 4 was the one which provided the highest bioaccessibility for iron and was the only one that differed from the others. About zinc, there was no significant difference between the treatments regarding the total rate as well as the bioaccessibility.

title: Production of flour made from bullfrog’s meat and bone

description: Abstract Bullfrog meat marketed in Brazil has been gaining ground among the population due to its soft flavor, low calorie content, and high protein content. It is recommended for treating gastrointestinal and allergic diseases. This study aims to maximize the use of bullfrog carcass by applying a heating technology that enables the use of bones in gastronomy, which contain high calcium bioavailability, and represent about 40% of the product’s total weight. A meat-and-bone flour called Low Cost Alternative Food has been developed, which, in addition to being functional and rich in protein and calcium, presents similar flavor to that of unmixed bullfrog meat, allowing food enrichment. Dehydration of the skeleton was carried out in an oven, and the remaining material was crushed and then vacuum packed, all in compliance with the standards for good manufacturing practices and under good sanitary conditions, making it microbiologically fit for human consumption for a total of 60 days while stored under refrigeration. Results showed a composition of 25% mineral matter, 60% protein which presented a 90% digestibility rate, only 12% fat, and 2% carbohydrates. This composition can compensate for calcium deficiency and malnutrition due to the quality of its protein.

title: Effects of alginate oligosaccharides treatment on preservation and fresh-keeping mechanism of shrimp during frozen storage

description: Abstract In this study, we investigated the influence of alginate oligosaccharides (AOS) coating on the quality of white shrimp (P. vannamei) at 4 ± 1 °C. We measured shrimp quality by surveying changes in certain properties, such as sensory quality, the microbiota, total volatile basic nitrogen (TVB-N), pH, and sensory characteristics. Compared to control group, AOS coating effectively stopped the growth of bacteria and decreased the formation of TVB-N (from 40% down to 30%). The pH of samples treated with AOS was visibly lower than that of the control group. The sensory quality of the AOS coated shrimp resembled microbial and physicochemical properties, and the acceptability was improved. Furthermore, we found the abundance of spoilage microorganisms, such as Shewanella and Pseudoalteromonas, in AOS coated groups is reduced compared to control groups. All these results suggest that our AOS coating treatment may improve storage and preservation of frozen shrimp.
