目的：研究壳聚糖涂膜处理对沙糖桔(Shatang mandarin)采后生理及品质的影响。方法常温条件下(20±2)℃采用0.5%、1.0%和1.5%壳聚糖涂膜处理,每4 d取一次样品,分别对沙糖桔果实的腐烂率、呼吸强度、可滴定酸含量、可溶性固形物含量和维生素C含量进行测定。结果与对照组相比,不同质量分数的壳聚糖涂膜处理均能有效抑制沙糖桔果实腐烂率的上升,延缓呼吸强度、可滴定酸、可溶性固形物和维生素C含量的下降。其中,1.5%壳聚糖涂膜处理对维持沙糖桔果实采后生理及品质的效果更显著。结论常温条件下,1.5%壳聚糖涂膜处理适用于沙糖桔果实的贮藏保鲜。

Objective To investigate the effects of treatment with chitosan on postharvest physiology and quality of Shatang mandarin. Methods Under normal temperature (20±2℃) , with 0.5%, 1.0% and 1.5%chitosan, the rotting rate, respiration intensity, titratable acid content, soluble solids content and vitamin C content of Shatang mandarin were determined with taking a sample every 4 d. Results Different mass fraction of chitosan coating processing could effectively restrain the increasing of rotting rate, delay the decreasing of respiration intensity, titratable acid content, soluble solid content and vitamin C content of Shatang mandarin compared with the control group. 1.5% chitosan coating treatment is more significant on keeping postharvest physiology and quality of Shatang mandarin. Conclusion It suggests that 1.5% chitosan coating processing applied to preservation and freshness of Shatang mandarin.
