초록
우리나라의 하천에 분포(分布)하고 있는 담수어(談水魚)의 식품학적(食品學的)인 기초자료(基礎資料)를 얻고져 비교적(比較的) 희귀종(稀貴種)에 속(屬)는 은어, 누치, 쏘가리 및 밀어 배육중(背肉中)의 핵산관련물질(核驗關聯物質), 유리(遊離)아미노산(酸) 및 구성(構成)아미노산(酸)을 분석(分析)하였다. 핵산관련물질(核酸關聯物質)은 IMP가 월등히 많아 은어, 누치, 쏘가리 및 밀어 배육중(背肉中)에
The composition of amino acids and the related compounds of nucleotides in the dorsal muscle of sweet fish Hemibarbus labeo, Mandarin fish Siniperca scherzeri and read fish Gobius similis was analyzed by amino acid autoanalyzer and high performance liquid chromatography. The result showed that IMP was dominant in the nucleotides of all the dorsal muscle of the fishes and a less amount of UMP, hypoxanthine and AMP was detected. In the free amino acid composition, the important amino acids were taurine and histidine in sweet fish, taurine, glycine and histidine in cornet fish, taurine, histidine and alanine in mandarin fish, taurine, proline and threonine in read fish, respectively, and in all the dorsal muscle of fishes, taurine was the dominant amino acid. In the amino acid compositions of the muscle protein, glutamic acid, glycine, aspartic acid and lysine were reached to 44.0% of total amino acids in sweet fish, glutamic acid, aspartic acid, lysine and glycine were 43.5% in cornet fish, glutamic acid, aspartic acid, lysine and leucine were 43.3%, 43.5% of total amino acids in mandarin fish and read fish, respectively. Glutamic acid was the dominant amino acid in all the fresh fishes.
