Rich in vitamin C (Vc) and chlorophyll, the Chinese kale shows nutritional value andsensory quality. The activities of ascorbate peroxidase and pheophytinase (PPH) associatewith Vc and chlorophyll degradation, have direct impact on the Chinese kale’s nutritionalvalue and sensory quality. It is valuable to study the gene expression and activity change ofthese two enzymes in Chinese kale’s growth and storage process. The effects of physical andchemical processing on gene expression and activity change of asco...
