Abstract
Supercritical fractional extraction of DHA and EPA from the mixture of fatty acids composing the fish oil was performed. The compositions, extracted quantities, and cumulative extracted quantities of fatty acids in the extract and the raffinate were investigated according to the fractional steps. The temperature and pressure for the miximum concentration of DHA and EPA in the extract or the raffinate were 60
초임계유체를 사용하여 네 종류의 추출조건에서 EPA가 20%, DHA가 15%인 물고기 기름을 구성하는 지방산에스터의 혼합물에 대하여 네 단계 분할추출실험을 수행하여 분할단계별 extract와 raffinate내의 성분무게조성, 추출되는 양, 누적추출량의 변화특성을 규명하였다. 네 가지 추출조건중 온도 60
