Barra de cereal proteica a base de quinoa e amendoim enriquecido com frutooli-gossacarídeo

Abstract

The food industry has sought to adapt to the trend of healthy consumption habits and, for this, it has invested in the research and production of products with functional purposes, since functional foods have proven to bring several health benefits. Therefore, it was proposed, with this research, the elaboration of a functional bar, rich in functional and protein ingredients, taking into account the nutritional content and its practicality of consumption. For this, varied proportions of quinoa (10%, 17% and 15%, for F1, F2 and F3, respectively) and peanuts (20%, 15% and 17%, for F1, F2 and F3, respectively), were used, and the functional bars were enriched with fructooligosaccharide (FOS), with a ratio between dry ingredients and binding agents of 70% and 30%, respectively. The design of the binary mixture was used for the various compositions of formulations. Analysis of variance (ANOVA) was applied to evaluate the physical-chemical composition and its average in relation to the Tukey test at 5% confidence. The three formulations were considered to have a high protein content (21.54%, for F1; 18.17%, for F2; 20.00%, for F3), according to legislation, with a high lipid content (22.02%, for F1; 13.42%, for F2; 22.40%, for F3), coming from good sources, and considerable carbohydrate content (49.62%, for F1; 54.44%, for F2; 47.84% , for F3), including fibers. The proposed functional bar proved to be balanced in nutrients and calories, presenting nutritional characteristics compatible with a diet rich in proteins.
