Abstract
The influences of three factors including calcium,UV-B radiation and hot water on the storage and the metabolism of reactive oxygen species(ROS) of longan flesh were investigated with orthogonal test in current works.The results indicated all treatments reduced the rate of fruit weight loss,conversely increased the rate of intact fruit.No significant influence on the TSS and TSS/TA of flesh was observed.The content of flesh titratable acid(TA) was reduced at the beginning of treatments,followed by an increase after the 5th day.All treatments reduced the content of MDA.The activity of flesh PPO was increased under treatment with calcium,while reduced under treatment of hot water.UV-B radiation gave almost no effect on the activity of PPO.All treatments reduced the activity of flesh POD,and had no influence on the activity of flesh CAT.Conclusively,all treatments could improve the storage effects and mitigate the ROS injuries,justifying the combination of calcium,UV-B radiation and hot water was the best treatment.Probably,ROS was scavenged by no enzyme protection systems.
