Abstract
Changes of free amino acids, nucleotides and their related compounds during the fermentation of yellow corvina entrails, Pseudosciaena manchurica, were analyzed. In fresh extract, alanine, glutamic acid, serine, lysine and leucine were dominant amino acids, and content of arginine, aspartic acid, cystine and tyrosine were low. The free amino acids analyzed in this experiment were not changed in composition but changed in amounts during the fermentation of yellow corvina entrails. Alanine, glutamic acid, lysine and leucine were abundant in both fresh sample and fermented products. Content of ATP, ADP, AMP and IMP decreased while hypoxanthine increased during the fermentation of yellow corbina entrails. The total free amino acid nitrogen at 30 day fermentation was 71% of its extract nitrogen. It is believed that such amino acids as glutamic acid, alanine, lysine, valine, leucine, nucleotides and their related compounds as hypoxanthine play an important role as taste compounds in fermented yellow corvina entrails.
특유(特有)한 풍미(風味)를 가진 조기속젓의 맛성분(成分)을 알기 위해 조기속젓 숙성중(熟成中)의 유리(遊離)아미노산(酸)과 핵산관련물질(核酸關聯物質)의 변화(變化)를 실험(實驗)하였다. 원료(原料)의 유리(遊離)아미노산(酸) 조성(組成)을 보면 함량(含量)이 많은 것은 alanine, glutamic acid, serine, lysine, leucine이며, 함량(含量)이 적은 것은 arginine, aspartic acid, cystine이었고 tyrosine은 흔적량에 불과(不過)하였다. 젓갈 숙성중(熟成中) 유리(遊離)아미노산(酸)의 양적(量的)인 변화(變化)는 있었으나 조성(組成)에는 변화(變化)가 없었고 원료(原料)에 많았던 alanine, glutamic acid, lysine, leucine 등의 유리(遊離)아미노산(酸)이 젓갈 제품(製品)에도 많았다. 조기속젓 숙성중(熟成中) ATP, ADP, AMP 및 IMP는 감소(減少)하고 hypoxanthine은 증가(增加)하여 숙성(熟成) 30일후(日後)에는
