摘　　要：菜籽油脱臭馏出物中含有丰富的维生素E,是获得天然维生素E的较好来源。本文采用溶剂萃取法,通过单因素试验和正交试验考察了萃取剂种类、萃取温度、苯甲醇体积分数等因素对萃取效果的影响。结果表明:以异丙醇-苯甲醇混合溶剂为萃取剂,在萃取温度60℃、苯甲醇体积分数为5%时,可以使原料中维生素E的浓度由3.8%提高到9.4%,为进一步提纯维生素E提供了较好原料。The extraction of natural vitamin E from by-production of rapeseed oil deodorizer distillate was studied. The effect of the kinds of extractants, the extracting temperature, the concentration of benzyl alcohol, and other factors on distribution coefficient were examined by single factor experiments and orthogonal experiments, and some simple mathematical models were proposed. In the end, some experiments were done to validate the conclusion. The result showed that the optimal processing conditions of the extraction as follows: extractant: mixture of isopropyl alcohol and benzyl, temperature: 60℃, concentration of benzyl alcohol: 5%, the best concentration of vitamin E was 9.4%.
