Abstract
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.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.
Claims8
A method for the hydrolysis of casein which comprises contacting casein with from about one to four gram equivalents of non-oxidizing mineral acid per gram atom of amino nitrogen in the casein at a temperature from 60.degree. to 100.degree. C. in the presence of acid activated montmorillonite and a member selected from the group consisting of orthophosphorous acid, salts of orthophosphorous acid and mixtures thereof.
