| 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(PME)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、PG活性的下降速度,降低可溶性果胶含量、PME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 the main problems in the storage of winter-jujube. In the humidicool storage, the insoluble pectincontent and pectinmethylesterases (PME) activity, soluble pectin content and polygalactouronase (PG) activity, cellulosecontent and Cx-cellulases activity, starch content and amylase activity of half-red Winter-jujube(Ziziphus jujuba Mill) wereassayed. Results showed that the humidicool storage could retard the decreasing rate of insoluble pectin content, starch contentand PG activity of Winter-jujube, inhibit the increasing of soluble pectin content, PME activity, Cx-cellulases activity andamylase activity, and accelerate late accumulation of cellulose content. |
