ABSTRACT:
A process for the total or partial elimination of aspartic acid and glutamic acid from a protein hydrolyzate or a mixture of aminoacids is described, which consists of passing the hydrolyzate or mixture of aminoacids in solution on an anion exchange resin and then washing with water or eluting the aminoacids from the resin. Aspartic acid and glutamic acid are at least partially separated from the other aminoacids because of their affinity for the resin which is greater than the affinity of the other aminoacids. The resulting mixtures of aminoacids may be used as such or may be further adjusted by addition of valine, leucine, isoleucine, and arginine to give products valuable in clinical nutrition.
