摘　　要：[目的]研究涂膜处理对灵武长枣低温贮藏期间抗氧化酶和PPO活性的影响。[方法]以灵武长枣为试材,研究海藻酸钠、壳聚糖、普鲁兰多糖涂膜处理对灵武长枣低温(0~4℃)贮藏期间抗氧化酶和PPO活性的影响。[结果]3种处理均显著延缓低温(0~4℃)贮藏期间灵武长枣SOD、CAT活性的下降速度,同时,有效抑制了PPO、POD活性上升速度。贮藏末期,各处理SOD、CAT活性均显著高于对照组,PPO、POD的活性均显著低于对照组,其中,壳聚糖涂膜处理和海藻酸钠涂膜处理效果最显著。[结论]该研究为灵武长枣的贮藏保鲜提供理论根据。[Objectie]To study effects of coating treatment on the activities of antioxidant enzyme and PPO of Zizphus jujubamill cv. lingwuchangzao during low temperature storage. [Method] Effects of coating treatment on the activities of antioxidant enzyme of Zizphus jujubamill cv. lingwuchangzao were studied at a low temperature（ 0-4 ℃）. [Result]Three treatments significantly retarded the decrease of SOD and CAT activities in Zizphus jujubamill cv. lingwuchangzao during storage at low temperature（ 0-4 ℃）,and effectively inhibited the activity of antioxidant enzymes PPO,POD. The activity of PPO and POD was lower than that of the control group. Among them,the effect of chitosan coating and seaweed sodium phosphate coating was the most significant. [Conclusion] The study provides a theoretical basis for storage and preservation of Zizphus jujubamill cv. lingwuchangzao.
