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.
