초록

건강식품으로 각광받고 있는 현미유는 palmitic acid, linolenic acid, oleic acid, stearic acid, tocopherol, squalene 등을 포함하고 있다. 본 연구에서는 국내산 현미겨로부터 초입계 이산화탄소를 이용하여 현미유를 추출하고, GC-MSD를 이용하여 조성을 분석하였다. 현미유의 추출량은 추출공정의 조작온도와 압력에 의존하였으며, 초임계 이산화탄소의 환산밀도에 따라 추출된 기름내 지방산의 조성이 변화되었다. 또한 70∼80%의 기름이 4시간 정도의 조작시간내에 추출된이 확인되었다. 특히 용매추출공정과 초임계유체 추출공정을 비교한 결과 초임계유체 추출공정에서 추출된 기름의 조성에서만 squalene이 포함되어 있음이 확인되었다.

Brown rice oil contains palmitic acid, linolenic acid, oleic acid, stearic acid, tocopherol, squalene, etc. The oil including essential fatty acids was extracted from the domestic brown rice bran using supercritical carbon dioxide(SCC) process, and the extracts were analyzed with GC-MSD. The extraction amount of brown rice oil was dependent upon the operating pressure and temperature, and the fatty acid composition of oil was varied with the reduced density(ρ_γ) of the SCC. About 70∼80% of brown rice oil was extracted in 4 hours. Especially, squalene which was not found in solvent extract phase was identified in supercritical fluid extraction phase only.
