Studies on the Utilization of Deodorized Condensates from Vegetable Oils

식물유 탈취유출물의 이용에 관한 연구
Jum Sik Kim

식물류 탈취추출물에 함유되어 있는 sterine과 tocopherol의 효율적인 분리정제방법을 검토하였다. 시료를 가열하여 수층과 유층으로 분리하고 유층을 취하여 메틸에스테르화한 후 지방산을 유거하였다. 잔유분을 비누화하여 불비누화분만을 유출, 농축한 후 메틸알코올에 녹여, 냉각함으로서 sterine을 분리하였다. 위의 모액을 메틸알코올에 녹인 후 -20℃로 냉각하여 유리지방산을 제거하고 이온교환수지로 처리하여 고농도의 tocopherol을 얻는 조건을 확립하였다.

An investigation has been performed to find an effective separation method of steriols and tocopherols from the deodorized condensates of vegetable oils. Simple heating of the starting mixture isolated the oil layer from water, and the former was collected. It was then methyl esterified followed by a distillation for the removal of fatty acid. The ensuing step was to saponify the residue. The unsaponifiable matter was extracted by both methanol and concentrated. The sterol was crystallized by cooling such concentrated solution. To obtain tocopherol, the mother liquor was first dissolved in methanol. Cooling this solution to -20℃ trapped fatty acid which was filtered out. The filtrate was then treated with ion exchange resin.
