A Study on the Taste Component in Fresh and Dried Fish

건조어육류(乾燥漁肉類)에 대(對)한 정미성분(呈味成分)의 변화(變化)에 관(關)한 연구(硏究)

The following is the test result of a clculation of the quantity of flavor content, that is, sixteen different kinds of free amino acid, found in both fresh and dried fish used widely as foodstuff here in Korea. 1. Throughout our test we were able to extract only a small amount of arginine though the amount of lysine, histidine, glycine, alanine and glutamic acid was comparatively large. 2. The test also showed that the amount of lysine decreased when a given fish dried up. The amount of methionine decreased in the case of Alaskan pollack though it increased in the case of Yellow corvenia. We also learned in our experiment that the amount of other flavor components increased though in varying degrees. 3. On the other hand, the content of free amino acid found in Yellow corvenia was much higher than in Alaskan pollack 4. And lastly, the test showed us that if and when the inflence of free amino acid is viewed strictly as a flavor-producing component, dried fish has much more flavor (and taste) than fresh fish.

한국에서 널리 식용(식용)하고 있는 동태와 조기의 생어(생어)와 건어(건어)의 정미성분중(呈味成分中) 16종(種)의 유리(遊離) amino 산(酸)을 건물량(乾物量)으로 환산(換算) 비교(比較)한 결과(結果)는 다음과 같다. 1) Arginine은 극미량(極徵量)만이 검출(檢出)되였고 Lysine, Histidine, Glycine, Alanine, Glutamic acid 등(等)은 비교적(比較的) 많았다. 2) 건어(乾魚)로 하였을 때 Lysine은 감소(減少). 하였으며 Methionine은 동태에서 감소(減少), 조기에서는 증가(增加)하였고 타성분(他成分)들은 차이(差異)는 있으나 모두 증가(增加)하였다. 3) 조기와 동태의 유리(遊離) amino 산(酸) 함량(含量)은 조기가 높았다. 4) 정미성분(呈味成分)으로서 유리(遊離) amino 산(酸)의 영향(影響)만을 고려(考慮)한다면 생어(生魚)보다 건어(乾魚)의 맛이 농후(濃厚)하다.
