An investigation has been performed to find an effective separation method of steriols and tocopherols from the deodorized condensates of vegetable oils. Simple heating of the starting mixture isolated the oil layer from water, and the former was collected. It was then methyl esterified followed by a distillation for the removal of fatty acid. The ensuing step was to saponify the residue. The unsaponifiable matter was extracted by both methanol and concentrated. The sterol was crystallized by cooling such concentrated solution. To obtain tocopherol, the mother liquor was first dissolved in methanol. Cooling this solution to -20℃ trapped fatty acid which was filtered out. The filtrate was then treated with ion exchange resin.
