Abstract

The extraction of volatile essential oil using supercritical carbon dioxide with 2%(v/v) ethanol and non-ethanol was performed in a semi-continuous flow extractor at the range of pressures and temperatures 6.9 to 17.2 MPa and 30 to 45$^{\circ}C$, respectively. When ethanol was added to the co-solvent, the solubility of volatile essential oils was increased up to 90% over the neat CO$_2$ value. The most efficiency of extraction of the voilatile essential oils was achieved at 13.8㎫ and 40$^{\circ}C$ by supercritical carbon dioxide with entrainer from Citrus junos peel.

초임계 이산화탄소를 이용한 유자과피로 부터의 휘발성 정유성분의 추출은 entrainer를 사용하지 않을 경우 압력 13.8㎫, 온도 4$0^{\circ}C$에서 756.61mg/sample 30g이 추출되었으며 entrainer를 7.4mL/min을 첨가하였을 경우 압력이 13.8㎫, 온도 4$0^{\circ}C$에서 5416.64mg/sample 30 g이 추출되어 약 7배의 추출량의 증가를 볼 수 있었다. 이는 보조용매를 첨가함으로서 초임계 이산화탄소의 유자과피의 휘발성 정유성분에 대한 용해력을 증가시키는데 큰 영향을 미치는 것으로 알 수 있다.
