Abstract Protein is one of the most important and most abundant components next to water in the living body, and it is also one of the main components in foods. In meat and meat products, proteins and amino acids are not only the main nutrients, but also are the material basis of food texture, flavor and color; besides, they have multiple functions, just like emulsifiers, gelling agents and stabilizers. Therefore, protein degradation in meat and meat products will greatly affect the quality. This article summarizes the main types of meat protein, changes in the structure and composition with protein degradation, and the impact of protein degradation on the quality of pork products. Moreover, the recent progress made in the research of related assays is described as well, aiming to provide a reference for related studies.
