title: Properties of wheat and rice breads added with chia (Salvia hispanica L.) protein hydrolyzate

description: Abstract Bioactive, technological and sensory properties of wheat and rice breads added of chia (Salvia hispânica L.) protein hydrolyzate were evaluated. The hydrolyzate was added to breads at concentrations of 1, 3 and 5 mg of hydrolyzate/g of flour. The specific volume, total score, bread crumb firmness, color, sensory analysis and antioxidant activity of breads were evaluated. The results showed that the protein content of the protein concentrate (79.56%) increased significantly compared with the defatted chia flour (32.52%). The results of antioxidant activity of chia protein hydrolyzate showed that at 0.50 and 1.0 mg of hydrolyzate/mL showed the highest values of activity by the DPPH method (66.09 and 65.43%). However, the chia protein hydrolyzate at 0.5 mg/mL presented the highest activity with a value of 83.74% by ABTS method. The reducing power results indicated that the hydrolyzate showed a dose-dependent relation since an increase from 0.50 to 2.00 mg/mL resulted in a significant increasing from 0.380 to 0.881 in absorbance. The addition of chia hydrolyzate resulted in good technological characteristics and antioxidant properties, in both breads. The breads with 3 mg of chia hydrolyzate/g flour had good sensory characteristics, which were not lower than those of the control breads.

title: Non-dairy cashew nut milk as a matrix to deliver probiotic bacteria

description: Abstract Cashew nut milk was evaluated as a matrix to deliver commercial probiotic strains (Bifidobacterium animalis, Lactobacillus acidophilus and Lactobacillus plantarum) in order to develop a non-dairy probiotic beverage. The first step was to evaluate the viability of the probiotic strains. All evaluated bacteria were able to survive in this food matrix under 4 °C for 30 days. So, B. animalis was the selected strain to perform a stability test of the beverage by monitoring the pH, color, sensory and microbiological quality during refrigerated storage for 30 days. During storage, B. animalis counts were above 107 CFU.mL-1, the microbiological quality was maintained and there was no significant difference in whiteness. A significant pH decrease was observed, but it did not affect the beverage’s sensory acceptance, indicating that cashew nut milk is an adequate vehicle for delivering probiotics.

title: Development of isotonic beverage with functional attributes based on extract of Myrciaria jabuticaba (Vell) Berg

description: Abstract Isotonic repositories are specially designed to promote rehydration during or after physical exercise. These beverages are processed for commercialization from synthetic flavorings and dyes with sensorial characteristics similar to those of fruits, in order to attenuate their natural acidity. The aim of the present study was to develop two formulations of isotonic drinks without synthetic dyes and with functional attributes based on concentrated hydroethanolic extracts of peel and pulp of Myrciaria jaboticaba. Determination of chemical (sodium, potassium and calcium, total phenolics, total anthocyanins, total flavonoids, total condensed tannins), physical (objective color analysis), and physical-chemical characteristics (pH, acidity, total soluble solids), as well as sensory evaluation through preference testing was carried out. In addition, the drinks presented dark red coloration, according to the chromaticity diagram. The sensory evaluation results revealed that the beverage formulated with 12% pulp extract stood out as the preferred beverage among the judges.

title: Optimization and characterization of vinegar produced from rice bran

description: Abstract The vinegar is a millenary food, appreciated by consumers worldwide. The rice bran is a rice-processing by-product produced in a large scale, mainly employed in feed. This study describes a method for defatted rice bran (DRB) vinegar production by submerged fermentation, with optimized aeration and stirring conditions, evaluating its physico-chemical properties and acceptance. A 22 Full Factorial Design (FFD) was applied to evaluate the aeration (0.25-1.00 VVM) and stirring (100-500 rpm) effect on the stoichiometric yield (SY), total concentration of ethanol and acetic acid yield (TCY), and acetic acid productivity (AAP). SY ranged from 26.26 to 79.97%, TCY ranged from 78.04 to 100.50%, and AAP varied from 0.056 to 0.473 g L-1 h-1. The stirring had a positive effect in the SY and TCY, while both aeration and stirring had a positive effect in the AAP (p ≤ 0.05). The FFD allowed an acetic acid increase of ≅ 750 times under aeration of 1.00 VVM and stirring of 500 rpm, which made it possible to develop an industrially compatible method for vinegar production using DRB as substrate. Furthermore, DRB presents potential for vinegar production, with functional characteristics - including antioxidant activity - and sensorially accepted.

title: Effect of heat treatment for liquefaction and pasteurization on antioxidant activity and phenolic compounds of Astragalus and sunflower-cornflower honeys

description: Abstract In this study, effect of heat treatments (liquefaction at 55 °C for 12 h and pasteurisation at 90 °C 15 sec) on total phenolic content, antioxidant activity and phenolic compounds of astragalus and sunflower-cornflower honeys was investigated. Total phenol content and antioxidant activity of honeys were assessed by Folin-Ciocalteu and ABTS methods, respectively. Phenolic profile was determined by HPLC-DAD system. Only pasteurisation process had a significant impact on sunflower-cornflower honey with regard to total phenolic content and antioxidant activity. Protocatechuic, 4-hydroxybenzoic, caffeic, p-coumaric, and ferulic acids, rutin, kaempferol were detected in astragalus honey, while 2,5-dihydroxybenzoic, chlorogenic, caffeic, p-coumaric, and ferulic acids, apigenin, rutin, kaempferol-3-glucoside, isorhamnetin-3-glucoside, quercetin, luteolin, kaempferol were detected in sunflower-cornflower honey. Pasteurisation significantly decreased caffeic acid in astragalus honey and other detected phenolics showed no significant difference after heat treatments. The impact of liquefaction process is lower than the pasteurisation process in terms of quantitatively phenolic compounds changes.

title: The influence of pasteurization and starter culture on methanol content and bio-profile of fermented Morinda citrifolia Linn. (Noni) fruit juice

description: Abstract Morinda citrifolia L., generally known as noni, is commonly used in Thai medicines and cuisine. Several bioactive phytochemicals have been isolated and identified from the noni plant, and their compositions differ based on the cultivars and harvesting period. Different types of fermented noni fruit juices (FNJ) were used as health supplement in several southeastern countries. The formation of a large amount of alcohol, especially methanol, in FNJ is one of the major hindrances to FNJ production. The current study explains the impact of starter culture (Lactobacillus plantarum SK15), pasteurization and addition of EGCG on alcohol content, bioactivity, and the physiochemical property of FNJ. The pH and sugar content of the samples were reduced during fermentation, while the organic acid content increased. The samples with EGCG obviously exhibited high total phenolic content and antioxidant activity. The level of pectin was high, and pectin methylesterase (PME) activity was low in EGCG-added samples compared with other samples. The alcohol content of the samples was under the permissible level of Thai standard; specifically, the methanol level was low in EGCG-added samples. Pasteurization and addition of starter culture did not influence any of the studied parameters. About 70% of acceptability index was observed for FNJ samples in the sensory evaluation. The study concluded that the addition of EGCG effectively reduced the alcohol content and improved the quality of FNJ. Also, further studies are required to reveal the role of starter culture in noni fruit fermentation.

title: A multivariate approach to differentiate yerba mate (Ilex paraguariensis) commercialized in the southern Brazil on the basis of phenolics, methylxanthines and in vitro antioxidant activity

description: Abstract The consumption of yerba mate beverages is related to several health benefits. These desirable properties are mainly due to the bioactive compounds. However, the levels of those compounds are directly affected by factors such as geographical origin. This study aimed to use chemometrics to evaluate the antioxidant compounds of yerba mate (consumed as chimarrão) marketed in southern Brazil. Neochlorogenic acid and caffeine were the main bioactive compounds found in this type of yerba mate beverage (chimarrão). The dataset was analyzed by chemometrics, and principal component analysis using the first three principal components explained 61.30% of the total variance. Hierarchical cluster analysis suggested three clusters, with cluster 1 containing the majority of the samples from the states of Rio Grande do Sul and Paraná, with higher levels of phenolics, methylxanthines, and antioxidant activity. The supervised methods, soft independent modeling of class analogy (SIMCA) and partial least squares-discriminant analysis (PLS-DA), had similar predictability (≥75% of accuracy) in terms of classifying yerba mate according to different Brazilian regions. Therefore, the chemometric tools used in the current study was suitable to monitor and assess a large variation of the antioxidant composition of yerba mate from different southern Brazilian states.

title: Performance evaluation of GSA, SOS, ABC and ANN algorithms on linear and quadratic modelling of eggplant drying kinetic

description: Abstract In this study, kinetics of eggplant drying was modeled in the laboratory-scaled Food Drying Oven (FDO) with resistance heater was designed and manufactured. The temperature, energy consumption and drying time of FDO were recorded by keeping the temperature of at different temperatures as 40, 50 and 60 °C. These saved values were chosen as the input parameters of the model. The weight value of the eggplant was taken as the output parameter. Linear and quadratic equations were developed for modeling and constant coefficients of these equations were estimated with Artificial Bee Colony (ABC), Gravitational Search Algorithm (GSA), symbiotic organisms search (SOS) algorithms. In addition, the performances of these models were compared with the model developed with ANN in terms of performance and time. The results show that the lowest error of the developed linear and quadratic equations was obtained with SOS algorithm. The MSE metric results of ANN were fifty times higher than the performance of SOS algorithm, and the SOS algorithm reached best value three times faster than the ANN.

title: Sensory quality of meat from Santa Inês lambs fed with guava (Psidium guajava L.) agroindustrial by-product

description: Abstract The aim of this work was to determine the sensory quality (flavour, odour, tenderness, juiciness and overall acceptability) and physicochemical characteristics of meat from Santa Inês lambs fed with diets containing guava agroindustrial by-product (GAB). Was used samples of the longissimus lumborum of 40 entire males with an average slaughter weight of 32.0 kg, after approximately 105 days in a feedlot. Animals were randomly placed into four treatments (10 replicates per treatment) and fed with different levels of GAB (0, 20, 40 and 60%). Among the attributes examined, only odour was not influenced by the GAB. Inclusion of 40% GAB in diets (in place of corn) produced meat which satisfied consumer demands in terms of fresh colour, although with less intense flavour and tenderness. Although the factors juiciness and overall acceptability did not differ among the highest levels of GAB, we recommend to use GAB addition of up to 40% to avoid compromising on animal performance and consumer sensory characteristics.

title: Influence of the addition of KCl and CaCl2 blends on the physicochemical parameters of salted meat products throughout the processing steps

description: Abstract The objective of this study was to evaluate the effects of different chloride salts (NaCl, KCl, and CaCl2) on the characteristics of salted meat products through the determination of moisture, pH, aw, chloride, ash levels, cooking loss, and instrumental color during the processing steps. Four salted meat treatments were elaborate using the following salts in the wet and dry salting steps: FC1: 100% NaCl; F1: 50% NaCl + 50% KCl; F2: 50% NaCl + 25% CaCl2; F3: 50% NaCl + 25% KCl + 25% CaCl2. The addition of CaCl2 led to the lowest pH and changes in aw, moisture, ash levels, and instrumental color when compared to the other treatments, which was different from the control (100% NaCl) and F1 (50% NaCl + 50% KCl), thus evidencing the great effect of CaCl2 on the characteristics of salted meat products during the whole processing. The partial replacement of NaCl by KCl and/or CaCl2 greatly increased the cooking loss of salted meat products. The replacement of NaCl by KCl promoted similar quality parameters.
