摘要: 本课题对不同方法直接萃取小麦胚芽油及用超临界CO2流体精馏麦胚油的方法进行了比较研究。结果表明:用乙醚提取的小麦胚芽油中维生素E的含量比用乙醇(90%)提取的要高;用超临界CO2萃取在压力为33MPa,温度为45℃时有最高的维生素E含量;用超临界CO2精馏在压力为19MPa,温差为△t=9℃时有较好的维生素E浓集效果。

Abstract: This subject compared different methods of extracting wheat germ oil with the method of refining wheat germ oilthrough supercritical CO2 fluid. The results showed that the vitamin E content in wheat germ oil extracted with diethyl ether washigher than that with ethanol in 90%;the optimum content was obtained at the conditions of P=33MPa and T= 45℃ throughsupercritical CO2 extraction, but more vitamin E was got at the conditions of P=19MPa and △t = 9℃ through supercritical CO2rectification.

Key words: wheat germ oil, VE, supercritical fluid, extraction, rectification
