초임계 이산화탄소를 이용하여 감태로부터 Fucoxanthin 농축

Concentration of Fucoxanthin from Ecklonia cava Using Supercritical Carbon Dioxide

  • 발행 : 2009.10.31

초록

초임계 이산화탄소를 이용하여 감태 내 지용성 색소인 fucoxanthin을 추출 및 농축하기 위하여 식물성 유래 지방산인 중쇄지방산이 선택되었다. 중쇄지방산을 이용하여 감태로부터 추출된 fucoxanthin 추출물로부터 초임계 이산화탄소를 이용하여 중쇄지방산만을 효과적으로 추출, 분리함으로써 잔존물 내에 효과적으로 fucoxanthin을 농축할 수 있었다. Fucoxanthin 농축에 높은 효율을 나타낸 세 가지 압력 및 온도 조건들로는 9.7 MPa에서 $40^{\circ}C$, 11.0 MPa에서 $45^{\circ}C$, 12.4 MPa에서 $50^{\circ}C$로 나타났다. 이 세 가지 온도 및 압력조건에서의 이산화탄소의 밀도는 거의 유사한 값을 나타내었다. 이상의 결과를 종합해보면 초임계 이산화탄소를 이용한 fucoxanthin의 농축에는 이산화탄소의 밀도가 매우 중요한 인자인 것으로 확인되었다.
