Abstract

In this paper, the degradation of nucleotides and their related compounds in conger eel muscle during sun drying was studied. The results showed that IMP was dominant in fresh conger eel, showing 75.5% of total nucleotides while the contents of ATP, ADP, AMP, inosine and hypoxanthine were low. The nucleotides tended to degrade rapidly during drying, only 6.2% of IMP remained after seven day's sun drying and ATP, ADP and AMP were also entirely disappeared. In consideration of flavor quality, it was consumed that sun drying is not an effective processing method of conger eel, as far as IMP is concerned.

붕장어의 선어(鮮魚) 및 천일건조중(天日乾燥中)의 산가용성(酸可溶性) 핵산관련물질(核酸關聯物質)의 변화(變化)를 실험(實驗)하여 다음과 같은 결과를 얻었다. 1. 생붕장어에는 IMP함량(含量)이 월등하게 많았고, ATP, ADP, AMP 및 inosine, hypoxanthine은 양(量)이 적었다. 2. 천일건조중(天日乾燥中) ATP, ADP, AMP는 거의 완전(完全)히 소실(消失)되었고, 생원료중(生原料中)에 가장 많았던 IMP$(16{\mu}moles/g,\;dry\;base)$도 1/16로 감소(減少)하였다. 한편 inosine은 12배로 hypoxanthine은 약 3배로 증가(增加)하였다. 3. flavor quality 면으로 판단한다면 천일건조중(天日乾燥中)은 붕장어 가공법(加工法)으로서 효과적(效果的)인 방법(方法)이 못된다고 볼 수 있다.
