Abstract: The invention relates to a method for the hydrolysis of milk protein using non-oxidising mineral acids at elevated temperatures, at which hydrolysis is performed in the presence of orthophosphorous acid and/or its salts and also of acid-activated montmorillonite to inhibit discoloration at temperatures of 60.degree.-100.degree. 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.
