摘  要:
【目的】以新鲜哈密大枣为原料,探讨干制温度对哈密大枣品质相关酶及指标的影响,为提高干制大枣品质新工艺提供理论依据。【方法】测定干制过程中哈密大枣多聚半乳糖醛酸酶、果胶甲酯酶、纤维素酶活性及果胶与纤维素含量,研究干制过程中哈密大枣品质相关酶及指标的变化趋势。【结果】干制过程中与哈密大枣品质直接相关指标包括多聚半乳糖醛酸酶、纤维素酶,果胶甲酯酶的活性及果胶和纤维素含量受干制温度的影响较大。【结论】干制温度对果胶和纤维素的含量及酶活性影响显著;多聚半乳糖醛酸酶、果胶甲酯酶、纤维素酶是影响大枣品质的重要酶。

摘  要:
【Objective】Fresh Hami jujube was used to study the effect of temperature on the quality of jujube in order to provide a theoretical basis for the new process to improve the quality of dried jujube.【Method】The related enzymes and trend indicators were measured by measuring Hami polygalacturonase,pectinmethylesterase,cellulase activity and pectin and cellulose content during the drying process. 【Result】The result showed that the direct enzymes related to the quality included polygalacturonase,cellulase,pectinmethylesterase; Pectin and cellulose content was significantly changed during the drying process. 【Conclusion】The effect of drying temperature on pectin and cellulose content and the activity of enzymes was significant; polygalacturonase,cellulase,pectinmethylesterase were important enzymes affecting the quality of jujube.
