| 摘 要： | 软化是冬枣贮藏中存在的主要问题之一。研究了湿冷贮藏对冬枣不溶性果胶含量和果胶甲酯酶(PM E)活性、可溶性果胶含量和多聚半乳糖醛酸酶(PG)活性、纤维素含量和纤维素酶(Cx-cellulases)活性、淀粉含量和淀粉酶活性的影响。结果表明,湿冷贮藏可以延缓冬枣不溶性果胶含量、淀粉含量和PG活性的下降速度,降低可溶性果胶含量、PM E活性、Cx-cellulases活性、淀粉酶活性的上升速度,而纤维素含量则表现为先慢后快的增长规律。

| Abstract: | Softening was one of main problems in the storage of winter-jujube. In the humidicool storage,the insoluble pectin content and pectinmethylesterases(PME)activity,soluble pectin content and polygalactouronase(PG)activity,cellulose content and Cx-cellulases activity,starch content and amylase activity of half-red Winter-jujube(Ziziphus jujuba Mill)were measured. Results showed that the humidicool storage could retard reducing of insoluble pectin content,starch content and PG activity of Winter-jujube,inhibit increasing of soluble pectin content,PME activity,Cx-cellulases activity and amylase activity,and accelerate evening accumulation of cellulose content. |
