| Abstract The aim of this study was to investigate the effect of acid pretreatment, temperature and enzyme concentration on the acid-enzymatic extraction of soluble collagen from chicken keel bone cartilage. A chemical composition analysis and protein profile characterization of this slaughter by-product were also conducted. The cartilages were extracted with 0.5 mol/L of acetic, lactic and citric acids for 24, 48 and 72 hours. Subsequently, optimization with a 22 factorial design was performed with three replications at the central point for a total of 7 experiments; the analyzed response was the collagen content of the obtained isolates. The cartilage under study has a high protein content (90.27% dry basis) consisting of approximately 35.7% collagen and... |

| Abstract Brazil is the world's largest producer of common beans (Phaseolus vulgaris L.), which are one of the most widely consumed grain legumes in the world. Seven improved genotypes of dry, coloured, Brazilian common beans were analysed for their nutritional (chemical composition, oligosaccharides, phenolic compounds and antioxidant capacity) and protein quality (amino acid profile, amino acid score, trypsin inhibitor activity and in vitro protein digestibility). The grain bean cultivars studied showed a high content of fibre, with some aromatic amino acids present at higher levels than the Food and Agriculture Organization reference protein. The dry beans had intermediate protein digestibility, ranging from 50.3% in the BRS Notável cultivar to 66.9% in... |

| Abstract The aim of the present study was to evaluate the physical and chemical quality of the brown soybean preserve in function of the ascorbic acid concentration and the maceration time, and also to evaluate the chemical composition, microbiological hazard, and acceptability of the best preserve, in addition verify its technological, nutritional, functional and sensory viability. The hardness of the grain ranged between 8.6 and 23N and was significantly affected by the maceration time. The ascorbic acid concentration influenced antioxidant activity (ranged between 4.3 and 183.8 mg100g-1) and total phenolic compounds (ranged between 176.4 and 466.2 mg100g-1). The best brown soybean preserve was obtained with a maceration time of 23 min and an ascorbic... |

| Abstract Food-type soybean, considered a functional and nutritious food, becomes an new alternative food in human nutrition, and its preserve is an option to the consumer market. The present study aims to verify the effect of maceration time of the grains and the acetic acid concentration in brine on the physical and chemical characteristics of a edible soybean preserves, and to evaluate the proximal composition, microbiological risk and sensory acceptance of the selected preserve. The methodology used was the response surface and the central composite rotational design. The presence of acetic acid in the brine was prejudicial to the quality of the edible soybean preserve - BRSMG 790A cultivar. The soybean preserve with the best characteristics was... |

| Abstract The use of the defatted baru almond (Dipteryx alata Vog.) prevents the production of waste residues after extraction of its oil (partially defatted baru flour), representing a process of interest from an environmental point of view. The aim of this study was to prepare oat cookies with functional properties, replacing 100% soy oil for baru oil and 30% wheat flour for partially defatted baru flour (baru cookie). Baru cookies presented a higher moisture (7.80%), probably due to the high content of dietary fiber (3.78%), resulting in a lower calorie content (457.46 kcal.100 g–1), compared to traditional oat cookies. Changing the formulation resulted in the enrichment of a number of microelements, including phosphorus (~ 197.90 mg.100 g–1) and iron (~... |
