The present invention prepares protein hydrolyzates by reacting selected protein material with at least one proteolytic enzyme and recovering the low molecular weight protein material by ultrafiltration while recycling the high molecular weight material and proteolytic enzyme for further hydrolysis.

The present invention prepares protein hydrolyzates by reacting selected protein material with at least one proteolytic enzyme and recovering the low molecular weight protein material by ultrafiltration while recycling the high molecular weight material and proteolytic enzyme for further hydrolysis. A series of ultrafilters of varying permeability may also be used.

A process for the hydrolysis of protein comprising the steps of: (a) hydrolyzing a selected protein material, dispersed in an aqueous medium together with at least one active proteolytic enzyme component, at a controlled temperature and alkaline pH; (b) separating the hydrolyzed protein material, by filtration employing a molecular weight-selective filter medium, into a lower molecular weight first protein filtrate fraction and a higher molecular weight second protein reject fraction, said second protein reject fraction including substantially all of the active proteolytic enzyme component; (c) recycling at least a portion of the second protein reject fraction to the hydrolysis step; and (d) recovering low molecular weight protein hydrolyzate from the first protein fraction.
