Abstract

|
Nitrogenous extractives and amino acids were analyzed with the dorsal muscle from wild and cultured bastard(Paralichthys olivaceus), and flounder (Pleuronichthys cornutus). Cultured bastard was higher in moisture content, and lower in crude lipid and protein content than those of wild one. Contents of free amino acids from wild and cultured bastard, flounder were 305.03㎎/100g, 253.42㎎/100g, and 340.1O㎎/100g, respectively. The profile of free amino acids in these samples was very similar, although there were a relatively difference in glycine, threonine, proline contents. Content of IMP in wild bastard (408.31㎎/100g) and cultured one (356.26㎎/100g) were higher than that of flounder (178.61㎎/100g). Wild bastard contained higher trimethylamine oxide and total creatinine than cultured one. Total amino acid contents of dorsal muscle from wild and cultured bastard, and flounder were 21.94g/100g, 20.12g/100g, and 17.63g/100g, respectively. The major amino acids of these samples were glutamic acid, aspartic acid, leucine and isoleucine.
