The effect of dehydration treatment on the browning ofActinidia argutaSieb.et Zucc during storage period at(20.0 ± 0.5) ℃ was investigated by observing changes in browning index,polyphenol oxidase(PPO),peroxidase(POD) and catalase(CAT) activities,and phenolic and malondialdehyde(MDA) contents.The results proved that appropriately dehydrated fruits could reduce the growth of browning index.The times of peak occurrence of PPO and POD activities were postponed and the peak values were reduced.In addition,the d...
