Abstract: From a physicochemical perspective, the internal factors causing meat quality changes mainly include fat and protein oxidation. Protein oxidation is a research hotspot recently. This review firstly summarizes the mechanism of protein oxidation in meat and protein covalent modification, the characterization of protein oxidation (the types of oxidative modification of proteins including carbonylation, sulfhydrylation and cross-linking). Then, the effect of protein oxidation on the eating quality of meat is deciphered from both microscopic and macroscopic perspectives. Finally, we propose some solutions to the problems in the field of protein oxidation that have not been fully resolved. We hope that this review can provide a reference for exploring the mechanism of muscle protein oxidation and its effect on the eating quality of meat.

Key words: protein oxidation; covalent modification; protein oxidation characterization; eating quality of meat
