초록

초임계유체와 마이크로웨이브 공정을 이용하여 불포화 지방산을 함유하는 아마란스유를 추출하였다. 초임계유체 추출의 경우 2000 psi에서 4000 psi까지 500 psi 간격으로 실험하였으며, 공정 온도는 40, 50, 70 ℃로 6h 동안 1h의 간격으로 추출하였다. 또한 초임계 이산화탄소의 낮은 극성을 보완하기 위해 공용매로 ethanol과 n-hexane을 사용하였다. 마이크로웨이브 용매추출은 ethanol과 n-hexane을 사용하여 에너지 세기를 각각 325, 390, 455, 520, 585W로 유지하고 30 min 이내로 추출을 수행하였다. 아마란스유 추출에 있어서 초임계유체 추출공정은 불순물이 함유되지 않은 순수한 오일을 추출할 경우에 추천될 수 있으며, 추출량을 증가시킬 경우에는 ethanol을 공용매로 사용하여 독성 잔류용매 문제를 배제하고 비교적 많은 추출량을 얻을 수 있었다. 마이크로웨이브를 이용한 공정의 용매로 ethanol을 사용할 경우 빠른 시간 내에 많은 양의 오일 추출이 가능하였다. 또한 squalene 선택적 추출의 경우에는 마이크로웨이브를 이용한 용매추출시 용매로 n-hexane을 사용하여 추출하는 것을 추천할 수 있다.

The amaranth oil including unsaturated fatty acids were extracted using supercritical fluid extraction (SFE) and microwave assistant solvent extraction (MASE). The composition of extract was identified with GC-MSD. In case of SFE, extraction pressure was increased from 2000 to 4000 psi at intervals of 500 psi, and temperature was maintained at 40, 50, 70 ℃, respectively. For the total extraction time of 6 hours, the extract amount was measured each 1 hr. Ethanol and n-hexane were used as the cosolvent to increase solvent power in SFE. In case of MASE, the solvent was ethanol and n-hexane. The amaranth oil was extracted under condition of 325, 390, 455, 520, 585 W irradiation power. We recommend SFE for the nontoxic and purification process of extraction, and MASE for a rapid extraction. The use of ethanol as the cosolvent in SFE and the solvent in MASE can increase th total extract amount. For the purpose of particular functional oil, squalene, use of n-hexane as the cosolvent in SFE and the solvent in MASE was found to be suitable.
