Effects of different transportation time on fruit quality of fresh jujube

In order to investigate normal temperature transportation time of fresh jujube under conventional packaging, effect of different transportation times（0, 2, 3, 4, 5, 6, 7 days）on quality of fresh jujube was studied, Jingcang 1 was selected as experiment material．Results showed that, with extension of transportation time, decay rate and weight loss rate of jujube gradually increased, and fruit decay rate significantly increased after 5 days of transportation．Peel turning red index increased, while color difference values of L* and b* continued to decrease, and a* value showed a rising trend．Total soluble solids（TSS）content showed a trend of first increasing and then decreasing, and reached a peak of 31% after 5 days of transportation．Results could conclude that transportation time of flat jujube should be within 5 days, which could better maintain commercial value of fruit, and provide a theoretical basis for storage, transportation, and preservation technology of fresh jujube．
