title: Hygienic-sanitary quality and effect of freezing time and temperature on total antioxidant capacity of human milk

description: Abstract Knowledge of the hygienic-sanitary quality of raw human milk helps to establish the best storage conditions for the preservation of its nutritional and functional components. Therefore, this study aimed to evaluate the hygienic-sanitary quality of human milk extracted at the mothers’ homes, and to analyze the effect of freezing time and temperature on the milk’s total antioxidant capacity. Milk of five mothers was evaluated individually for Staphylococcus aureus, total aerobic mesophilic counts, mold and yeasts, total and thermotolerant coliforms. The milk pool was stored at -8 °C, -18 °C and -40 °C for 2, 4, 8 and 15 days and analyzed for the total antioxidant capacity by the 2,2-diphenyl-1-picrylhydrazyl free radical and 2,2-azino 3-ethylbenzothiazoline-6-sulfonic acid scavenging methods. The microbiological analyses of the raw human milk samples indicated counts of all the studied microorganisms above the safe limits. Related to the effect of freezing time and temperature on total antioxidant capacity, it was concluded that, regardless of the freezing temperature, a significant reduction occurred on total antioxidant capacity over time and that the lower the storage temperature, the greater its total antioxidant activity.

title: Impact of processing conditions and gelling agent on physical and sensorial properties of pecan oil-dulce de leche gummy candies

description: Abstract For the development of gelatinized dairy products that include emulsified pecan oil as an unsaturated fatty acid source the incorporation of hydrocolloids becomes necessary and their properties must be carefully selected. This work aimed to study gelatinized candies made with 0% milk fat dulce de leche with pre-emulsified pecan nut oil using combinations of gelatin (4.67 to 7 g/100 g) and high methoxyl pectin (1.33 to 2 g/100 g) as gelling agents. The effect of different drying methods (vacuum-oven at 35 °C for 24 h and freeze-drying) was evaluated. Control samples without drying were also studied. Dehydration conditions significantly (p &lt; 0.05) affected aw, texture (hardness, cohesiveness, adhesiveness, gumminess, springiness, and resilience) and color parameters (L*, a*, b*) of products, being higher than the effect of the gelling agent. Formulations were selected based on texture and aw criteria and sensory evaluated by appearance, color, texture, taste, and overall acceptability. Two formulations (one with 7% gelatin and 1.33% high methoxyl pectin content, and the other with 2% high methoxyl pectin and 4.67% gelatin content), both with low moisture content and vacuum-dried, exhibited good acceptability. These pecan oil-dulce de leche gummy candies would represent a healthier candy version, low in saturated fatty acids, and source of oleic acid.

title: Chemical characterization and antioxidant potential of native fruits of the Cerrado of northern Minas Gerais

description: Abstract This study aimed to chemically characterize the pulps of the tropical fruits araticum (Annona crassiflora), buriti (Mauritia flexuosa), coquinho azedo (Butia capitata), cagaita (Eugenia dysenterica), and cajá (Spondias mombin), with a focus on antioxidant potential and microminerals. Calcium levels in the Araticum pulp are 9.35 mg/100 g and the iron content was 4.78 mg/100 g. In cagaita pulp, the calcium content was 15.35 mg/100 g and magnesium content was 66.00 mg/100 g. The iron content present in coquinho pulp was 11.47 mg/100 g and in cagaita it was 11.53 mg/100 g. The extracts with the highest contents of total phenolic compounds were araticum (433.80 mg GAE/g) and coquinho (173.5 mg GAE/g). Araticum pulp had the highest antioxidant potential because it had the lowest EC50 (0.04 mg/mL). The results presented here demonstrate the great potential of the fruits of the Cerrado in terms of rich mineral nutrients and bioactive compounds.

title: Evaluation of texture of cheese by-products incorporated bread

description: Abstract This work aimed to develop new breads incorporating whey residue, “sorelho”, obtained from ewe’s milk after the production of Serra da Estrela Cheese. For this, we baked three types of bread: wheat bread (control sample), bread incorporating sorelho, and another version containing additional nutritional elements. The texture was evaluated with a texturometer, using compression and perforation tests. Results showed that sorelho can be successfully incorporated in bread. The best product was the bread with sorelho plus improved nutrition, which presented good textural characteristics during a period of 24 hours. This trend was observed for all properties evaluated: hardness, chewiness, resilience, cohesiveness, springiness (compression test) and external firmness, inner firmness, stickiness, adhesiveness (perforation test). Finally, factor analysis showed: FACTOR 1 – compression textural properties; FACTOR 2 – perforation firmness properties and FACTOR 3 – perforation adhering properties, which in total explained approximately 81% of total variance.

title: Occurrence of pathogenic and spoilage bacteria in salmon sashimi: histamine and antimicrobial susceptibility evaluation

description: Abstract The study of the hygienic sanitary conditions of raw consumed meat foods, such the sashimi, is necessary to define their quality and possible health consequences for the population. Sixty samples of salmon sashimi (Salmo salar) were collected from ten restaurants in the city of São Luís, Maranhão, Brazil, six from each site. The samples were analyzed for coliform counts at 35 °C, coliforms at 45 °C and positive and negative coagulase Staphylococcus, presence of Escherichia coli, Salmonella sp., Vibrio parahaemolyticus and Aeromonas spp, antimicrobial susceptibility test of the isolates and quantification of histamine in the samples. The results showed high counts of coliforms at 35 °C and 12 samples with &gt;102 NMP/g of coliforms at 45 °C, presence of E. coli and Salmonella in 3 samples each, absence of V. parahaemolyticus and coagulase positive Staphylococcus and coagulase negative Staphylococcus count between &lt;20 and 5.0x104 CFU/g, presence of Aeromonas in 95% of the samples, 60 isolates being A. hydrophila and 6 A. caviae. For susceptibility to antimicrobials, E. coli isolates were sensitive to CPM, CTX, LVX, PPT and SUT, two isolates were resistant to AMP; one resistant to GEN, one to AMI and one to AMC. Salmonella isolates were sensitive to AMC, CPM, CFO, CRX, GEN, LVX and PPT, one resistant to AMI and one to AMP and SUT. The isolates of Aeromonas were resistant on mean to five of the antimicrobials, with AMP (97%), CRX (90.9%) and AMC (77.3%), and 81.8% were sensitive to CPM. Histamine levels ranged from 44.06 ± 0.74 to 505.46 ± 8.83 mg/kg, 21 of the samples with levels higher than 100 mg/kg. The samples presented unsatisfactory sanitary hygiene conditions and public health risks, due to the detection of pathogenic bacteria and high concentrations of histamine capable of causing scombroid poisoning, and isolates show multiresistance to the tested antimicrobials.

title: Phenolic profiles of faveleira (Cnidoscolus quercifolius Pohl) seed and press cake extracts: potential for a new trend in functional food

description: Abstract The objective of the present study was to assess the phenolic compounds and antioxidant capacity of faveleira seed and press cake extracts. Phenolic profiles were assessed by Ultra-High Performance Liquid Chromatography (UHPLC). Furthermore, the Total Phenolic Content (TPC) and DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging were evaluated. The faveleira seed and press cake extracts are sources of natural phenolic compounds in human diet and have potent antioxidant activity. Gallic acid was the predominant phenolic compound in seed and press cake extracts. The study showed that faveleira seed and press cake extracts can be considered functional foods as well as a potential interest to the food industry.

title: Physical, chemical and nutritional evaluation of flours prepared with pulp and peel of green banana from different varieties

description: Abstract Processing of green fruits for flour production can be considered an option to minimize post-harvest losses and add value to the product. This study aimed to evaluate the physical, chemical and nutritional composition of flours prepared with pulp and peel of green banana from different varieties. Silver bananas, plantains, and apple bananas were used to produce the flours. Drying was carried out in an oven at 105 °C for 12 hours. Analyses of pH, moisture, ash, carbohydrate, protein, lipid, fiber and starch contents were performed. All the flours produced showed adequate moisture content. As for fiber content, the flours prepared with all banana varieties presented good results, which was due to the fact that the peel was preserve in their production. High starch content was observed for plantains and apple bananas, which reinforces the large amount of starch found in the green fruit. All flours had low caloric value. The results showed the feasibility of using green banana flour ) prepared with pulp and peel of these varieties mainly because of the fiber content, thus validating the present study. It is also worth mentioning the importance of producing green banana flour with peel, aiming to maintain a greater amount of nutrients, sometimes found in the peel, as well as enabling the full use of the fruit.

title: The increase of atherogenic index on fatty acids composition as a consequence of trans fat acids reduction in industrialized foods: the Brazilian scenery

description: Abstract The use of fats with a low melting point is attractive to the food industry, as it contributes to improving the texture, color and stability characteristics of the food. These fats are obtained from vegetable oils through some processes such as hydrogenation or interesterification. However, the partial hydrogenation process leads to the formation of trans fat. In several countries, actions have been taken to eliminate the presence of elaidic acid, a trans fatty acid (C18: 1t) from processed foods. This trans fatty acid and palmitic acid, a common saturated fatty acid (C16: 0) are proven to be atherogenic. The aim of this work was to evaluate the composition of fatty acids of 39 types of commercialized foods in Brazil, including cookies, snacks, wafers, instant noodles, frozen sandwiches and pizzas, mixtures for food preparation, microwave popcorn, margarines, spreadable cheeses and pastry dough. The lipids were extracted and their Fatty Acid Methyl Esters (FAMEs) identified by Gas-Chromatography (GC). The fatty acids found in greater quantity were oleic, linoleic and palmitic acids; whereas the trans fatty acids were detected in 51.3% of the samples. On the other hand, when trans fast were reduced in some foods, it could be observed increases in the palmitic acid (C16:0) content. This high content of palmitic acid is justified by the addition of palm oil and its derivatives, which can be used in interesterified oil mixtures or can be directly used in industrialized food formulations, even without interesterification. Governments and organizations in favor of human health should be aware that the use of dietary fatty acids which compromise the atherogenic index is not a healthy alternative. Consumers should therefore be alerted to the risk of consuming foods containing these fats until the food industry is banned from using them or finds healthier alternatives for making food.
