Method for hydrolysis of casein using orthophosphorous acids or salts thereof and montmorillonite

摘要

The invention relates to a method for the hydrolysis of casein using non-oxidizing mineral acids at elevated temperatures, at which hydrolysis is performed in the presence of orthophosphorous acid or salts thereof acid-activated montmorillonite to inhibit discoloration at temperatures of 60 DEG -100 DEG C. The method in accordance with the invention is technically simple and can be undertaken economically and it supplies the desired protein hydrolysate with high yield without the formation of undesirable by-products, especially undesirable dark substances, which result in discoloration of the end product.
