Abstract

PURPOSE: Tocopherol and tocotrienol in vegetable oil are concentrated by extracting the vegetable oil with a specific solvent and distilling off the solvent, whereby the concentration is economically and efficiently conducted by simple operations.
CONSTITUTION: Vegetable oil containing tocopherol and tocotrienol such as palm oil, rice bran oil or soybean oil is extracted with a solvent of a monohydric lower alcohol or a mixture thereof with a ketone. The amount of the solvent used is 20W 80pts.vol., preferably 40W50pts.vol. per 100pts.wt. of the oil. Then, the extraction mixture is stood and separated into one phase soluble in the extraction solvent and the other phase soluble in the coil. The solvent-soluble phase is distilled to obtain the objective concentrate as a distillation residue. Since this process does not contain chemical reactions such as esterification or saponification, the oil is not damaged and the separation is readily effected by very simple operations.
