| 摘 要： | 研究了在冷藏(7±1)℃条件下3种不同浓度(1.0%、1.5%和2.0%)的壳聚糖处理对纽荷尔脐橙果实采后生理生化及贮藏效果的影响。结果表明:壳聚糖处理能延缓脐橙果实可溶性固形物、可滴定酸、Vc的下降;抑制果实呼吸强度;减少果实水分的损失和果实腐烂;延缓果实保护性酶类SOD、CAT活性的下降,从而延长果实贮藏寿命。其中2.0%处理效果最好。

| Abstract: | The effects of three concentrations(1.0%,1.5%,2.0%) chitosan coating treatments on storage quality and post-harvest physiology of Newhall navel orange stored at low temperature(7±1)℃were investigated.The results showed that chitosan treatments could delay the loss of soluble solids content(SSC),vitamin C content and titratable acid in fruits.The respiration rate of fruits was well controlled.The loss of water and decay rate of fruits were also inhibited.The loss of antioxidant enzymes SOD and CAT activity was delayed and thus prevent the degradation of Newhall navel orange.The best treatment was 2.0% Chitosan. |
