Abstract

Free amino acid extracts of musculus brachiocephalicus and musculus glutaeus of cattle, swine, goats and rabbits are analyzed to see the composition and the contents of free amino acids by thin layer chromatography and automatic amino acid analyzer. The results obtained are summarized as follows: 1. Meats of cattle, swine, goats and rabbits analyzed by thin layer chromatography have 6 kinds of free amino acids such as glycine, histidine, methionine, lysine, alanine and leucine, and the spots of glycine in chromatogram of meats of cattle, swine and goats and the ones of methionine in chromatogram of meats of rabbits are the largest and the most denes of all other ones. 2. Distribution curves of free amino acids in meats of cattle, swine, goats and rabbits showed significant differences, but differences on distribution curves of free amino acids between musculus-brachiocephalicus and musculus glutaeus of the same tested animal are not significant. 3. Contents of free amino acids in meats of cattle, swine, goats and rabbits showed significant differences, but differences on contents of free amino acids between musculus brachiocephalicus and musculus glutaeus of the same tested animal are not significant.
