A method for separating and purifying natural tocopherol from soybean oil deodorization by-products

摘要

The present invention relates to a method for separating and purifying natural tocopherol from a soybean oil deodorization by-product, which comprises dissolving a soybean oil deodorization by-product as a fat-soluble organic solvent, adding an alcohol containing water, alcohol or water to remove the sterol mixture, And then dissolving it in a polar organic solvent and introducing it into a basic anion exchange resin and eluting it with an acidic organic solvent. This is a method for separating and purifying natural tocopherol of high purity at a high yield from soybean oil deodorization byproduct.
