Caracterização nutricional de misturasà base de arroz parboilizado, soja e uva e seus efeitos em parâmetros biológicos de ratos Wistarem crescimento.

Abstract

Brazil is considered one of the countries that more agro-industrial waste produced, due to the intense agricultural activity. As an example of this fact is the Grits of grape bagasse, rice and soy flour that can be used as ingredients in the preparation of new products for human consumption. The objective of this study, to characterize nutritionally mixtures with a basis of parboiled rice, defatted soy flour and grape Marc and their effects on biological parameters of Wistar rats after weaning, seeking alternatives for a healthy nutrition in growth phase. The work was structured in two experiments, where in experiment I were compared, nutritional and microbiological parameters, phenolic compounds, anthocyanins and antioxidant activity in parboiled rice, soy flour, defatted and grape marc. In experiment II were evaluated the biological responses of male Wistar rats in growth, fed with diets containing different proportions of parboiled rice, soy flour and grape marc. The results allow to conclude that the greatest concentration of soybean in the supplement, cause weight gain, increase in cholesterol, glucose and epididymal fat, however promotes growth. The increase in concentration of rice and grape Marc in the supplement, causes an increase in the area of the femur, decreases triglyceride levels and does not alter the levels of cholesterol and epididymal fat. Supplementation with rice, soya and grape residue, does not cause change in liver function and its use in feed on growth period.
