Ever-Fresh(주성분(主成分) : kusayate) 처리(處理)가 붕장어, 보리새우, 학꽁치, 빙장중(氷藏中)의 선도유지(鮮度維持)에 미치는 효과(效果)를 실험(實驗)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. K치(値)는 붕장어, 학꽁치 및 보리새우의 사후(死後) 초기(初期)의 신선도(新鮮度)를 판정(判定)하는 좋은 지표(指標)가 될 수 있다. 2. 보리새우의 사후(死後) 초기(初期)의 선도판정(鮮度判定)에는 VB-N도 좋은 지표(指標)가 될 수 있다. 3. Ever-Fresh 처리(處理)는 붕장어, 학꽁치, 보리새우의 빙장(氷藏) 초기(初期)의 선도유지(鮮度維持)에 효과(效果)가 있었다. 4. Ever-Fresh 처리(處理)는 보리새우 빙장(氷藏) 초기(初期)의 산화방지(酸化防止) 효과(效果)가 있었다.
In this paper, the effect of Ever-Fresh, a kind of preservatives for fish and shellfish, on fish and shrimp during ice storage were investigated. The results are as follows: 1. K value representing the ratio of optical densities of inosine and hypoxanthine fraction and total nucleotide fraction at 250nm could be useful as an index to measure the freshness of fish and shrimp during ice storage. 2. Volatile basic nitrogen could be also useful as an index to measure the freshness of shrimp during ice storage. 3. Ever-Fresh treatment of conger eel, half-beak, and shrimp appeared effective on keeping freshness during the early stage of ice storage. 4. Ever-Fresh treated shrimp showed lower thiobarbituric acid value as compared with the control during the early stage of ice storage.
