Abstract: A method for reducing the content of a saturated hydrocarbon in oils and/or fats. The method includes subjecting raw material oils and/or fats to a short path distillation treatment under a temperature condition of 50° C. or higher and 270° C. or lower. In the short path distillation treatment, a feed rate of the raw material oils and/or fats to a short path distillation apparatus may be 30.0 kg/h·m2 or less per unit area of an evaporation surface of the short path distillation apparatus. The feed rate may be 5.00 kg/h·m2 or more and 25.0 kg/h·m2 or less per unit area of an evaporation surface of the short path distillation apparatus.

Abstract: A method of producing refined oils and/or fats whereby the content of, e.g., glycidol, can be reduced and reductions in the content of tocopherols can be inhibited, and a method for producing low-impurity tocopherols. The method includes a first distillation step of subjecting raw material oils and/or fats to thin film distillation under a first condition; a second distillation step of subjecting a first distillate fraction obtained after the first distillation step to thin film distillation under a second condition; a third distillation step of subjecting a second residual fraction obtained after the second distillation step to thin film distillation under a third condition; and a mixing step of obtaining a mixed oil by mixing a first residual fraction obtained after the first distillation step, with a third distillate fraction obtained after the third distillation step. The first, second, and third conditions include specified temperature conditions and pressure conditions.
