| Flours with different physicochemical and functional properties were obtained from malted corn. Response surface methodology (RSM) was used to study the effects of malting time (1,3, 5 days), malting temperature (20, 25, 30º C) and gibberelic acid concentration (0.0; 0.5; 1.0 %) on these properties. The chemical composition and paste viscosity of flours were significantly affected by malting time and temperature, while water solubility index (WSI) and water absorption index (WAI) varied only with malting time. Gibberelic acid did not significantly influenced any of the studied properties. Germination at 20-25ºC for 3 days was recomended to obtain corn flour with high WAI, low viscosity and medium WSI, without excessive loss of proteins. |

| Abstract Response surface methodology (RSM) was used to optimize the ultrasound-assisted extraction parameters of perilla protein isolate (PPI), which has functional properties. A central composite experimental design was applied to investigate the effects of three factors (ultrasonic power, extraction time, and liquid-to-solid ratio) on six responses: protein yield, water solubility index (WSI), water absorption capacity (WAC), oil holding capacity (OHC), emulsifying activity (EA), and foaming ability (FA). Based on the RSM results, the optimum conditions were an ultrasonic power of 206 W, and extraction time of 32.4 min, and a liquid-to-solid ratio of 10.34:1. Under these conditions, PPI had high protein yield (26.1%) and functional properties (55.2%... |

| Abstract This work aims to investigate the incidence of two color abnormalities in broiler meat: PFN (Pale, Firm, Non-exudative) and PSE (Pale, Soft, Exudative), as well as the physicochemical alterations promoted by those anomalies. The samples of broiler breast meat (n = 700) were classified as Normal (44<L*<53, pH>5.8), PSE (L*≥53, pH<5.8) and PFN (L*≥53; pH>5.8). The occurrence of Normal, PSE and PFN samples was 69%, 11% and 20%, respectively. PFN samples presented a 4.2% higher water-holding capacity compared to PSE meat. PSE meats displayed a higher MFI (89.4) when compared to PFN and Normal meats. It was also noticed that the levels of lipid oxidation were greater in PSE breasts compared to Normal breasts. The total carbonyl in PFN,... |

| Baru (Dipteryx alata Vog.) is an abundant legume in the Brazilian Savanna. Its nuts can be exploited sustainably using its protein and lipid fractions. This study aimed to analyze the proteins of the nuts present in the defatted flour and protein concentrate in terms of their functional properties, the profile of their fractions, and the in vitro digestibility. The flour was defatted with hexane and extracted at the pH of higher protein solubility to obtain the protein concentrate. The electrophoretic profile of the protein fractions was evaluated in SDS-PAGE gel. The functional properties of the proteins indicate the possibility of their use in various foods, like soybeans providing water absorption capacity, oil absorption capacity, emulsifying... |

| Significant initiatives exist within the global food market to search for new, alternative protein sources with better technological, functional, and nutritional properties. Lima bean (Phaseolus lunatus L.) protein isolate was hydrolyzed using a sequential pepsin-pancreatin enzymatic system. Hydrolysis was performed to produce limited (LH) and extensive hydrolysate (EH), each with different degrees of hydrolysis (DH). The effects of hydrolysis were evaluated in vitro in both hydrolysates based on structural, functional and bioactive properties. Structural properties analyzed by electrophoretic profile indicated that LH showed residual structures very similar to protein isolate (PI), although composed of mixtures of polypeptides that increased hydrophobic... |

| Abstract The present study assessed the physical, chemical, functional, and microbiological properties of cocoyam (Xanthosoma spp.) corm flour made from the Nazareno cultivar. The flour was initially submitted to a water-soaking process in order to reduce its high oxalate content. The soaked flour showed a high dietary fiber content (15.4% insoluble and 2.8% soluble fiber), and can be considered essentially an energy-rich food given its high starch content (60.5%), of which 85.04% was analyzed as amylopectin; it also showed a high potassium content (19.09 mg/g). The anti-nutritional component analysis showed low levels of oxalate (5.55 mg/g), saponins (0.10%) and tannins (0.07%), while phytates were not detected. The flour had a high water and oil... |
