Enriquecimento nutricional de farelos de espécies oleaginosas do cerrado e farinha de Araruta (Maranta Arundinacea) tratadas com os fungos Pleurotus Ostreatus e Pleurotus Sajor-Caju visando a elaboração de um produto para alimentação humana

Abstract

Productive sectors in Brazil, such as agro-industry, generate a variety of residues, such as bagasse, fruit peels, seeds and bran from the extraction of oils, potentially rich in several nutrients. In animal feed, these residues are already being used as nutritional components or roughage in rations. For human food, waste has great potential as ingredients rich in protein, fiber, minerals and antioxidants, among others. Thus, the oil extraction residues of native species or adapted from the region were subjected to microbiological processes with edible fungi, aiming at the formulation of products of high nutritional efficiency in the human diet, in addition to adding commercial and economic value. In this work, the potential for nutritional enrichment of different substrates obtained in the extraction of macaúba (A. aculeata), sesame (Sesamum indicum) and arrowroot (Maranta arundinacea) oil was evaluated, with the fungi Pleurotus ostreatus and Pleurotus sajor-caju. The nutritional parameters of substrates and their mixtures, were evaluated before and after bioconversion. The bioconversion technique improved the nutritional parameters of all samples, especially in terms of dietary fiber and protein. The best performance was observed with the fungus Pleurotus sajor-caju. Compared to sesame bran, which showed the best nutritional results, all mixtures also showed increases in nutritional values after bioconversion with both P. ostreatus and P. Sajor-caju.
