Abstract:
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.
