Abstract
As a local fresh jujube species in Chongqing, Wulong loin jujube has high nutritional value and excellent flavor. But the storage period of Wulong loin jujube was very short, and this was the reason why its industry development was hindered the development. In this study, fresh Wulong loin jujubes were coated with chitosan at different concentrations (1.0%, 1.4%, and 1.6%), and then they were stored at （1±0.5） ℃ with 90% relative humidity to examine the preservation effects of chitosan coating. The results showed that the dosages of 1.4% chitosan coating could delay the reductions of firmness, and Vc and the contents of soluble solids. It was also found that the rot fruit rate was effectively reduced, and all the targets above were superior to CK group after stored for 60 days.
