ABSTRACT:
A process for producing efficiently and economically without using strong acids nor strong bases, .alpha.-amino acids from .alpha.-amino acid amides by hydrolyzing .alpha.-amino acid amides in an aqueous medium in the presence of ammonia. If necessary, the resultant hydrolyzate liquid from which .alpha.-amino acid has been removed may be reused.
