Abstract

대두유에 포함되어 있는 대표적 불포화 지방산인 oleic, linoleic 및 linolenic acid를 선택적으로 분리하기 위한 기초 자료를 얻기 위하여 실리카 겔에 함침시킨 한 모델 용액을 초임계 이산화탄소 및 entrainer를 포함하는 초임계 이산화탄소로 추출하였다. Benzene과ethylacetate는 oleic acid를 선택적으로 추출하는 유망한 entrain -er로 밝혀졌으며 그 효과는 GC에 의한 친화력 평가 결과와 잘 일치하였다.

The objective of this work is to obtain the basic data for the selective extraction of unsaturated fatty acids from soybean oil. a model mixture containing oleic, linoleic, and linolenic acid supported on silica gel was extracted with supercritical carbon dioxide and supercritical carbon dioxide plus an entrainer. It was found that benzene and ethylacetate were promising entrainers for separating oleic acid and the effect of these entrainers was in accordance with the result predicted by GC affinity test.
