- 1 -PROCESS FOR THE TOTAL OR PARTIAL ELIMINATION OF ASPARTIC ACIDAND GLUTAMIC ACID FROM PROTEIN HYDROLYZATES AND MIXTURES OFAMINOACIDS, AND AMINOACID COMPOSITIONS THEREFROMHAVING HIGH NUTRITIVE VALUE.Abstract of the DisclosureA process for the total or partial elimination ofaspartic acid and glutamic acid from a protein hydrolyzateor a mixture of aminoacids is described, which consists ofpassing the hydrolyzate or mixture of aminoacids in solutionon an anion exchange resin and then washing with water oreluting the aminoacids from the resin. Aspartic acid andglutamic acid are at least partially separated from theother aminoacids because of their affinity for the resinwhich is greater than the affinity of the other aminoacids.The resulting mixtures of aminoacids may be used as such ormay be further adjusted by addition of valine, leucine, iso-leucine, and arginine to give products valuable in clinicalnutrition.
