Study on the Methods of Extracting Vitamin E from the Wheat Germ

Abstract

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
