Abstract

PURPOSE: To obtain the titled concentrate useful as vitamin E, an antioxidant, etc. in a high concentration and high yield, by esterifying free fatty acids in a deodorized distillate of a fat or oil previously with an alcohol, and adsorbing the treated fatty acids on a specific silica gel.
CONSTITUTION: An alcohol, e.g. methanol, ethanol or ethylene glycol, is added to a deodorized distillate formed as a by-product in the deodorizing step of a fat or oil, e.g. soybean oil or rapeseed oil, or a material, containing tocopherol, e.g. α-, β- or γ-tocopherol, and prepared by concentrating the distillate to esterify free fatty acids therein. The resultant material is concentrated if necessary and then dissolved in a nonpolar solvent, e.g. petroleum ether or hexane. The soltuion is then treated with a spherical silica gel having an average pore diameter of 70W100Å to adsorb the tocopherol, which is then extracted with a polar solvent, e.g. diethyl ether, from the silica gel.
