고온가압에 의한 연어 frame 추출물의 제조조건

Abstract

This study was conducted to investigate optimal conditions for preparation of extracts from salmon frame using an autoclave. According to the results of various extraction conditions (extraction method, extraction time, volume and pH of extraction solution, and necessity of re-extracting), higher quality extracts could be prepared by adding salmon frame into 3 times (vol/wt) of water to raw material, and then autoclaving for 4 hrs before filtering extracts with cheese cloth. For efficient use as basic materials of liquid or powder Gomtang, however, fish odor of the extracts prepared under optimal condition should be improved.
