Protein oxidation‐induced changes in the physicochemical properties and quality of plant food

Abstract

SummaryProtein oxidation is widely present in food systems and is susceptible to internal factors involving lipids and enzymes as well as external factors such as temperature and oxygen promoters. Protein oxidation leads to modification of the peptide skeletons and amino acid side chains, which in turn alters the structural characteristics of proteins, including protein cleavage, aggregation and derivative formation, and severely affects their physicochemical properties and bioavailability, thereby reducing the edible and storage qualities of foods. This review summarises the main factors that cause and regulate oxidation of plant protein, the effects of protein oxidation on food quality and strategies to ameliorate protein over‐oxidation, aiming to provide meaningful information for the development of high‐quality plant protein products.
