| Abstract: | Objective] The aim was to study the preservation of fresh Chinese wolfberry fruit via chitosan coating.Method] Using Chinese wolfberry "Ningqi No.1" as experimental material,the fresh fruits were coated by difference concentrations of chitosan(0.75%,1.00%,1.25%,1.50% and 1.75%) at room temperature to study the changes in weight loss rate,rate of fruit rot,soluble solid content and vitamin C(Vc) content.Result] Of all the treatments,the fruits coated with 1.25% chitosan showed lowest rate of fruit rot and weight loss rate,and highest Vc and soluble solid content,presenting the optimal fresh-keeping effect.Conclusion] Chitosan coating is helpful for the preservation of fresh Chinese wolfberry fruit at room temperature. |
