Abstract：
 This invention disclose a new technology for extracting vitamin E and sterol from deodorization distillates of plant oils, taking lipase as the calalyst replacing conventional strong acid and strong base to catalyze fatty acid and neutral oil and fat to generate transecterification reaction to generated fatty acid monoester from the plant oil deodorization distillates under normal temperature and pressure to extract vitamin E and sterol by conventional rectification technology based on the feature of easy separation of vitamin E, sterol and these fatty acid monoester.
