Influence of hydrogen peroxide on the ROS metabolism and its relationship to pulp breakdown of fresh longan during storage.

ABSTRACT: The influence of hydrogen peroxide (H₂O₂) on the ROS metabolism and its relationship to pulp breakdown of fresh longan cv. Fuyan during storage was evaluated. Contrasted to control fruit, H₂O₂-treated samples manifested a higher index of pulp breakdown, an enhanced rate of O₂ ^-. generation, and an increased amount of MDA, but lower APX, CAT and SOD activities, reduced expressions of DlAPX, DlCAT and DlSOD, and lower concentrations of total phenolics, flavonoid, AsA, and GSH as well as lower levels of free radicals scavenging capacity. These data revealed that H₂O₂-induced pulp breakdown of longan was because H₂O₂ reduced ability of removing ROS but increased ROS gener
