摘要
以冬枣为试材,研究了冬枣在81.1KPa、50.7KPa、20.3KPa、101.3KPa(常压)4个不同压力下的生理生化变化。结果表明:低压抑制了果实的呼吸强度、MDA含量的积累以及LOX活性和POD活性,减缓了相对电导率和总糖含量的增加,降低了Vc的损失,减慢了转红速度,延缓了果实的衰老进程。生产中可以选用50.7kPa或者81.1 kPa的低压条件贮藏冬枣。
The physiological and biochemical changes of Dongzao Jujube under the conditions of 81. l kPa, 50.7kPa, 20. 3kPa, 101.3kPa were studied. The results showed that hypobaric condition inhibited respiratory rate, accumulation of MDA content, activity of LOD and POD, retarded the rising of relative conductivity and the content of sugar. Loss rate of Vc and change of colour were slowed down. Low pressure delayed the course of senescence. 50.7kPa or 81.1 kPa is the best pressure for hypobaric storage during production.
