| Oviductus ranae (OR) is a traditional Chinese medicine, which was first recorded in the Compendium of Materia Medica in the Ming Dynasty. OR contains high amounts of proteins and elicits therapeutic effects on neurasthenia, insomnia, and respiratory symptoms, which are related to oxidative stress and immunodeficiency. This study aimed to obtain the potential of OR for the development of functional food possessing antioxidant and immune-enhancement functions in the same dose. In antioxidant evaluation, OR can significantly decrease malondialdehyde and protein carbonyls (P < 0.05, P < 0.01) and significantly increase total superoxide dismutase and glutathione in a dose-dependent manner (P< 0.05, P < 0.01) against ethanol-induced oxidative stress... |

| ABSTRACT: The present study evaluated the effects of baru nut consumption on body weight, percent adiposity, amount of adipose tissue and blood levels in obese male Swiss mice. After inducing obesity by providing high-glucose diet (60 days), the mice were divided into 4 groups (7 animals per group) and were fed on a control diet (C), high-glucose diet (HG) or high-glucose diet added with baru (HGBA) or soybean oil (HGSO). Groups fed with diet HGBA had a decrease in the weight gain and glucose and triglyceride levels when compared to diet HG. Aimals fed with HG exhibited a higher proportion of epididymal and retroperitoneal adipose tissue. The inclusion of baru nut in the diet improved the control of weight gain and glucose and triglyceride levels in obese... |

| Starch factories generate large amounts of cassava solid waste. A small amount is utilized for animal feed but most of it is discharged with deleterious effects to the envirounment. A edible food with a high content of insoluble dietary fiber (60.9%), named "partially hidrolyzed cassava waste" (PHCW), was prepared from industrial cassava solid waste by an enzymatic process. PHCW or wheat bran (WB) were fed to model rats and both promoted digestive function effects, but PHCW produced the greatest effect. The insoluble fiber constituent from PHCW (and not the soluble fiber), promoted the greatest fecal bulking, fecal weight and defecation frequency in rats, as compared to WB. Such results indicate that the partially hydrolyzed cassava waste presents... |

| In recent decades, studies on human nutrition have emphasized the importance of omega-3 and 6 intake. Since flaxseed is a good source for such fatty acids, the aim of this study was to develop a Brazilian cheese roll enriched with flaxseed flour. Three formulations were produced to determine the intensity of some sensory attributes and to set the best composition for conducting a consumer acceptance test. In the selected formulation, it was determined the Brazilian cheese roll's expansion rate, its physico-chemical characteristics, fatty acid composition and acceptance rate. Regarding its flavor and general characteristics, the results showed a good acceptance of the cheese roll enriched with flaxseed flour. The product also presented an omega-6/omega-3... |

| ABSTRACT Improvement of quality-related traits of grains is a constant concern in white oat breeding programs, which challenges breeders to understand their dynamics. The performance of different genetic combinations must be thoroughly evaluated to make high nutritional quality cultivars available. This study aimed to estimate the heterosis on F1 and F2 generations, vigor loss, due to inbreeding, and correlation between the grain chemical components to understand the dynamics of these traits, considering two segregating oat progenies. The populations Albasul × UPF 15 (population 1) and IAC 7 × UFRGS 19 (population 2) were developed. Both populations showed transgressive segregant individuals. The combination Albasul × UPF 15 provided significant heterosis... |

| Pleurotus ostreatus is able to bioaccumulate several metals in its cell structures; however, there are no reports on its capacity to bioaccumulate iron. The objective of this study was to evaluate cultivation variables to increase iron bioaccumulation in P. ostreatusmycelium. A full factorial design and a central composite design were utilized to evaluate the effect of the following variables: nitrogen and carbon sources, pH and iron concentration in the solid culture medium to produce iron bioaccumulated in mycelial biomass. The maximum production of P. ostreatus mycelial biomass was obtained with yeast extract at 2.96 g of nitrogen L−1 and glucose at 28.45 g L−1. The most important variable to bioaccumulation was the iron concentration in the cultivation... |

| The stress imposed on plants by soil flooding constitutes a major barrier to growth and productivity. The identification of soybean varieties that produce higher levels of isoflavones, is necessary as soybeans have been used as human food to reduce risks of chronic diseases. Thus, this study was conducted with the objective of quantifying proteins and isoflavones in soybean cultivars subjected to flooding at various stages of development. The cultivars 'BRS267', 'BRS257' and 'BRS213' were subjected to 15 days of flooding, starting at the stages V6 and V8 and 11 days under stress starting at the stage R4. The proteins in the grain were extracted and quantified and analyzed by SDS-PAGE electrophoresis. Isoflavones were extracted, separated and quantified on... |
