In this study, the impact of high oxygen atmospheric packaging (HOAP) on hydrogen peroxide (H2O2) production, and on the content of hemicellulose, cellulose, lignin, and protein accumulation in Chinese flowering cabbage (Brassica campestris L. ssp. chinensis Makino) was assessed by using air packages as a control. The results showed that HOAP efficiently reduced the H2O2 levels in the stem of Chinese flowering cabbage during the storage process. An increase in tissue firmness, and significant reduction in the content of hemicellulose, cellulose, and lignin in the stem were observed upon HOAP treatment. The activities of peroxidases (POD) and laccases were also suppressed. Furthermore, proteomic profiling revealed a total of 63 differentially expressed proteins, of which oxidative stress-related proteins (enzymes) were found to be the major proteins that were regulated by HOAP treatment. The reduction in hemicellulose, cellulose, and lignin biosynthesis regulated by H2O2 signal was probably related to the differential accumulation of oxidative stress-related proteins that were induced by the HOAP treatment.
