Abstract

The invention discloses a method for co-producing fatty acid methyl ester, vitamin E and phytosterol from carclazyte oil.The method comprises the steps that firstly, fatty acid in the carclazyte oil is completely converted into fatty acid methyl ester; secondly, fatty glyceride in the carclazyte oil is converted into fatty acid methyl ester, and then fatty acid methyl ester is obtained through reduced-pressure distillation; thirdly, after ester residues are processed through freezing crystallization to obtain a first batch of coarse sterol, the vitamin E is obtained through molecular distillation, freezing crystallization is performed again to obtain a second batch of coarse sterol, two batches of the coarse sterol is washed with acetone and then dried, and a sterol product is obtained.According to the method, secondary development on the carclazyte oil extracted from a byproduct waste carclazyte generated during grease processing is achieved, not only is the carclazyte oil used for producing fatty acid methyl ester, but also the ester residue byproduct generated in the producing process is further recycled and utilized, the high-economic value natural vitamin E and phytosterol of the byproduct are extracted and recycled, the economic value of the carclazyte oil is excavated in a maximized mode, and the additional value of the carclazyte oil is achieved.

Description

technical field [0001] The invention relates to a method for co-producing fatty acid methyl ester, vitamin E and phytosterol by using clay oil. Background technique [0002] Vitamin E and phytosterols are mainly derived from vegetable oils. Soybean, corn germ, cottonseed, and sunflower seeds are rich in vitamin E and certain phytosterols. Vitamin E can eliminate free radicals in humans and animals, protect biofilm stability, delay photoaging, anti-aging, anti-tumor, prevent and treat cardiovascular diseases, maintain and enhance reproductive function, and promote gonad development. Food, feed, cosmetics, health products and other products. Phytosterols can effectively reduce the cholesterol level in serum, prevent and treat hypertension, coronary heart disease and other diseases; they also have various physiological properties such as anti-inflammation and hindering the formation of cancer cells. The existing production and extraction process of vitamin E generally uses th...
