Abstract:
     The present invention concerns the method and products of extracting protein hydrolysis products by enzymatic reaction on protein containing wastes. The features of this method consists in adding proteolytic enzyme to the protein substrate, filtering off the insoluble matter after the reaction is complete, and drying the filtrate in a spray dryer to obtain dry solid protein powder. In case that the filtrate is acidic or alkaline, it is neutralized by ionexchange resin before drying. The protein product obtained by this method is edible, and can be used as cultural medium for microorganism in place of refined protein gel on the market. It offers cheap raw material for food products, fermentation and pharmaceutical industries.
