Title:
METHOD FOR EXTRACTING NATURAL VITAMIN E FROM DEODORIZED DISTILLATE OF RICE BRAN OIL
Document Type and Number:
WIPO Patent Application WO/2019/214422
Kind Code:
A1
Abstract:
The present invention relates to the technical field of biochemical extraction, and specifically provides a method for extracting natural vitamin E from a deodorized distillate of a rice bran oil. The method comprises firstly removing most free fatty acid in a deodorized distillate of rice bran oil by using high vacuum rectification to reduce the amount to be treated in subsequent enzymatic esterification, then converting, by means of a lipase, the remaining components, such as the free fatty acid, triglyceride and sterol ester, in the deodorized distillate of the rice bran oil, which has been subjected to high vacuum rectification, into components such as fatty acid monoesters, glycerinum and free phytosterol, and finally extracting the natural vitamin E derived from prepared rice bran oil by means of a molecular distillation technique. The method has a simple process, is green and environmentally friendly, the quality of the product thereof is good, in particular, the content and yield of tocotrienols is high, and has a bright industrial application prospect both in terms of production process and production cost.
