Df. Hwang et al., SEASONAL-VARIATIONS OF FREE AMINO-ACIDS IN THE MUSCLE AND VISCERA OF SMALL ABALONE HALIOTIS-DIVERSICOLOR, Fisheries science, 63(4), 1997, pp. 625-629
Seasonal variation in the level of free amino acids was investigated i
n the muscle and viscera of cultured small abalone Haliotis diversicol
or. Among free amino acids in the small abalone, the predominant one w
as taurine, followed by arginine, glycine, glutamic acid and alanine.
The muscle contained higher amounts of total free amino acids, taurine
, arginine, and glycine than the viscera, but the latter had more glut
amic acid than the former. The levels of total free amino acids,taurin
e, and taste-active amino acids including arginine, glycine, glutamic
acid, and alanine in the muscle of small abalone sampled from October
to January were higher than those from other seasons. The result of fr
ee amino acid analysis was generally consistent with the fact that the
small abalone was more tasty in the autumn and winter seasons.
