The invention relates to a method to extract a natural
vitamin E, a phytosterin, and a
fatty acid methyl ester by the
enzyme catalysis and the molecular
distillation, which is characterized in that a
triglyceride in a distillate which is deodorized from a
vegetable oil is hydrolyzed into a
fatty acid through a
lipase, a
methanol is catalyzed by the
lipase and the
fatty acid is esterified and generated into a
fatty acid methyl ester, and the natural
vitamin E and the phytosterin are produced when the
methanol and the
fatty acid methyl ester are processed by filtering, desolventizing, freezing and removing the phytosterin, and removing the
fatty acid methyl ester through the secondary molecular
distillation. The the extraction method of natural
vitamin E, phytosterin, and fatty acid methyl este, compared with the prior art, has the advantages of adopting the process that the oil is catalyzed and hydrolyzed first and then the
enzyme catalyzes the fat to be esterified and to be processed by the secondary molecular
distillation, no producing
wastewater, shortening the esterification time, increasing the natural
vitamin E content, deploying the secondary freezing and
crystallization to remove the phytosterin with high
recovery rate of phytosterin, and beneficially increasing the purity of the
vitamin E.
