Abstract

Effects of stage treatment of SO2 releaser combined with Ice-temperature storage(SSR-IT) on storage life of longan(Dimocarpus longan Lour.'Shixia') fruit were studied.Compared to the fruit in traditional 3 ℃ storage,the pericarp colour of the SSR-IT fruit was improved significantly,which was represented by the increase of h value.The respiration rate was inhibited dramatically,the PPO activity was reduced and the membrane permeability was enhanced remarkably.A high good fruit rate with 91.15% in 48 days was reached and the good quality of pulp was maintained,and the contents of Vc,TSS and TA were maintained at high level as well.Compared to the fruit stored at ice-temperature plus SO2 releaser,the SO2 residue in pulp of SSR-IT fruits was much lower.
