PURPOSE: Provided is a method for producing lignan powders having excellent antioxidation effects, the lignan powders produced thereby and method for preventing oxidation by adding the lignan powders to meat and meat processed product. CONSTITUTION: The lignan powders are produced by (i) mixing sesame oil or sesame dreg with spirituous ethanol in a ratio of 1: 1 to 1:3, followed by stirring to separate an ethanol layer; (ii) filtering the separated ethanol layer and concentrating the filtrate under a reduced pressure; (iii) adding ethanol to the concentrate to crystallize lignan powders; and (iv) separating the crystallized lignan powders, followed by heating and drying. The lignan powders produced by this way have excellent antioxidation effects. In order to prevent oxidation of raw meat and meat processing product, the lignan powders are added in an amount of at least 0.05 % by weight based on the total weight of the meat or product.
