ABSTRACT:
A method of purifying hydrolyzed protein compositions by contact with a substantially phase-incompatible fluid extractant is provided. A reduction in the concentration of chlorohydrins, measured as 3-monochloro-1,2-propanediol, in hydrolyzed protein compositions can be obrtained by contacting the hydrolyzed protein composition with such a phase-incompatible fluid extractant, e.g., ethyl acetate. The method allows removal of chlorohydrins without substantially affecting the organoleptic qualities of the hydrolyzed protein.
