During the process and storage, food protein is prone to be oxidized influenced by unsaturated fatty acids、metal ions、flavor、oxidative enzymes and other promoting oxidation components. Protein oxidation causes changes in protein structure and physical and chemical properties, but there was no report whether the dietary oxidized protein would cause changes in physiological activity of the body. In this paper, effects of soy protein modified by the heating and lipid peroxidation product MDA on the redox state...
