Primary raw materials of the natural composite antioxidant are Chinese herbal medicines such as dried orange peel and Liquorice; and the natural composite antioxidant is prepared by mixing the following raw materials in parts by weight: 20-30 parts of dried orange peel antioxidant, 50-60 parts of Liquorice antioxidant, 2-3 parts of lecithin, 1-2 parts of vitamin C and 2-3 parts of citric acid. The preparation method has the advantages that different antioxidant components are compounded in a certain proportion, so that the resistance to oxidation is higher than that of the same dosage of single antioxidant; D101 type macroporous adsorption resin is used for refining the dried orange peel antioxidant for the first time; the Liquorice antioxidant is purified by using repeated precipitation method; the technological content is high; and the method is innovative. Moreover, according to the invention, orange peels which are wa
