【Abstract】 Radiation of 60 Co γ can promote the lipid oxidation of foods.During the beginning period of preservation,there was not significant difference of lipid oxidation rates between the radiated foods and their controls.With elongation of preservation time,the lipid oxidation rates of the radiated foods increased obviously.Differently radiated foods showed different lipid oxidation rates.The effect of preservation temperature on lipid oxidation of the radiated foods was relatively great.The higher the preservation temperature,the higher the lipid oxidation rate.But the effects of preservation temperature on lipid oxidation of differenly radiated foods were not the same.The antioxidant apparently inhibited the effect of radiation on lipid oxidation of foods.The antioxidant can also inhibit the effect of preservation temperature on lipid oxidation of the radiated foods. ]更多还原
