摘要
[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 different 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 rotten fruits 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 rotten fruit 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.
