QUANTITATIVE DETERMINATION METHOD OF AMINO ACIDS CONTAINED IN AMINO ACIDS-ZINC COMPLEX

摘要

PROBLEM TO BE SOLVED: To provide a method of easily, accurately, reproducibly, quantitatively determining amino acids contained in amino acids-zinc complex such as crystalline L-carnosine zinc complex formed by configuring at least one amino group of the amino acids and one carboxyl group on zinc.;SOLUTION: A slurry-like sample is prepared by adding acetic acid to slurry formed by adding formic acid of 10-60 ml (25°C reference) to amino acids-zinc complex of 1 g and stirring them, and amino acids contained in the amino acids-zinc complex in the sample are quantitatively determined by titrating the sample using perchloric acid.;COPYRIGHT: (C)2007,JPO&INPIT
