Obtaining Protein Hydrolyzates By-products of Agaricus Bisporus

Abstract

Abstract The mushroom industry generates non-marketable by-products that are not used or misused, these by-products are rich in protein and other beneficial compounds for health. Currently there is great interest in products rich in protein from agro-industrial waste, in this study was used mushroom by-products to obtain protein concentrates and isolates in order to improve functional properties, using a biotechnological process based on the use of proteases, with an effective approach for the maximum recovery of the components, maintaining their quality and effectiveness. It was used 4 different proteases (Alcalasa®, Flavourzyme®, Papain and Bioprotease LA-450) to determine which of them is most effective, the most efficient proteases that lead to a higher hydrolysis degree is used Bioprotease LA-450 and Alcalasa® (6.65 ± 0.6 and 6.21 ± 0.9) respectively, obtaining a higher amount of solubilized products (46.3 ± 3.6% and 41.7 ± 3%), as well as the Bioprotease LA-450, who presents a higher content of total proteins (51. 9 ± 4.8). This hydrolyzate, due to its composition: rich in amino acids, oligopeptides and peptides, can be used as a biofertilizer in agronomy, and as a nutraceutical or nutricosmetic in food or cosmetics.
