摘要: 运用壳聚糖作为涂膜剂处理韭薹,在4℃条件下储藏保鲜30d。储藏期间对韭薹的失重率、腐烂率、花苞开放率、花苞增重率、纤维素和VC含量进行了测定。实验结果表明:壳聚糖涂膜对韭薹有明显的保鲜效果,其中1%~1.5%壳聚糖涂膜有较好的保鲜效果,能够明显抑制韭薹腐烂和纤维素含量的增加和保持较高的VC含量。

Abstract: In this study, leek-balts were soaked with chitosan solution to form a coating on their surfaces. During 30 days stored at 4℃ , the weight loss, decaying index, opening rate of boot, weight increase of boot, fibrin, and VC content of the leek balts were investigated. The results showed that chitosan coating has preserves fresh effects on leek-blats of the treatments, 1%~1.5% chitosan coating shows better fresh keeping effects on leek-balts store, with less weight loss, better blooming rate, and weight increment of boot and fibrin content, and higher content of chlorophyll and vitamin C.
