PURPOSE:To produce foods, fats and oils from which the generation of soapy flavor is prevented, by a method wherein a specified additive is added to fats and oils contg. lower fatty acids or to foods using such fats and oils. CONSTITUTION:Crude rice bran oil is purified with an alkaline material. The resulted neutral oil in alkali foots is saponified and then treated with dilute sulfuric acid to produce dark oil which is then distilled under reduced pressure to obtain a distillation residue (A) of the rice bran dark oil. The alkali foots of rice bran oil is extracted with a neutral monohydric lower alcohol. The resulting extract is acidified to separate a viscous material (B). An additive selected from (A) the residue and (B) the viscous material in an amount of 0.01-1.0% based on the weight of fats and oils is added to fats and oils contg. lower fatty acids (e.g. hardened coconut oil, palm kernel oil, etc.) or foods (e.g. chocolate, ice cream, etc.) using the fats and oils. |
