Various methods have been proposed to separate tocopherols from substances containing low concentrations of tocopherols, such as deodorized distillate, deodorized sludge, hotwell oil soapstock, etc., which are produced as by-products in refining processes such as deodorizing vegetable oils and fats. However, industrially, there were problems in terms of yield and simplicity.

As a result of research to develop a method for separating tocopherols that is industrially more advantageous than conventional methods, the present inventors conducted a methyl esterification reaction to separate tocopherols from low-concentration tocopherol-containing substances produced by-product in the refining process of vegetable oils and fats. The reaction product is treated with a strong basic resin, and the tocopherols adsorbed on the resin are subjected to an elution operation,
In the method for separating tocopherols, (1) a methyl esterification reaction is carried out in toluene, (2) the toluene layer of the methyl esterification reaction product is directly treated with a strong basic resin, and (3) a methyl esterification reaction is carried out in toluene. By eluting the tocopherols adsorbed on the resin using toluene as a developing solvent, the same organic solvent, toluene, can be used primarily as both the esterification reaction solvent and the developing solvent for the elution operation, thereby achieving the above objective. This discovery led to the completion of the present invention.

The toluene layer may be separated from the obtained methyl esterification reaction product and treated directly with a strong basic resin, but it may also be treated using a column.
