PROBLEM TO BE SOLVED: To provide a method for producing a sesame-treated product containing lignans from the defatted lees of sesame, treated with microorganisms. SOLUTION: The microorganisms are inoculated in the defatted lees of the sesame, and cultured to treat the leas with the microorganisms, and after a prescribed time, water in the treated defatted leas is removed. The resultant lees are extracted with alcohols such as methanol and ethanol, and the residue is further extracted with an organic solvent such as ethyl acetate. The solvents of the product extracted with the organic solvent in combination with the product extracted with the alcohols are distilled off to provide the objective extract. The extract can be utilized as an antioxidant containing the lignans as it is, and, if necessary, can be further purified by solvent partition. |
