摘要
A method is provided for manufacturing high-purity vitamin E compounds by selectively separating vitamin E compounds such as tocotrienols and tocopherols from oil raw materials such as deodorized distillate, and more specifically, a method is provided, applying to a rich fraction of vitamin E compounds, for obtaining high-purity vitamin E compounds by separating and removing only free fatty acids contained as impurities. The method comprises a process in which a solution containing vitamin E compounds and free fatty acids is placed in contact with a weakly basic anion exchanger, and the free fatty acids are preferentially adsorbed.
