Abstract
Continuous direct enzymatic protein solubilization process for industrial wastes. The present invention involves a sequential enzymatic process which enables solubilizing proteins that are present in determined industrial wastes, permitting the use of by-products. The wastes used can be of plant origin (rice bran, algarroba seed, etc.) or animal origin (Procambarus clarkii or American crab). The main process includes two steps: a first step of successive washings with acidified water and a second step of continuous enzymatic hydrolysis. Variants to the main process are shown without pretreatment of the wastes with acidified water. These solubilized protein wastes (peptones) have an application, among others, in the formulation of culture media, in the biosynthesis of pharmaceutical and food products, in clinical or dietetic nutrition, as additives in cosmetics and as components of organic fertilizers.
