Abstract:In the process of food processing and storage，protein oxidation is easy to occur，which leads to a change in protein structure and the decline of digestive characteristics，causing damage to the digestive organs and other parts of the body. In this paper，the effects of protein oxidation on its structure，digestive characteristics，and body health in recent years were reviewed，and the commonly used analysis techniques of protein oxidation and common means of inhibiting protein oxidation were summarized，so as to further reveal the mechanism of protein oxidation and inhibit protein oxidation and provide theoretical basis for maximizing the retention of food nutritional value，extending the storage period，and reducing the waste of food resources.
