摘要: 本文研究了桐柏大枣在11%O2、0%CO2气调(CA)贮藏条件下的几种酶活性的变化。结果表明,CA贮藏桐柏大枣对淀粉酶活性没有显著影响,但能够降低多聚半乳糖醛酸酶(PG)活性低。CA贮藏的PPO活性高于CK,具有诱发褐变的可能性。CA贮藏可以有效地保持过氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)的活性,有利于延缓衰老进程。

Abstract:  The changes of some enzyme activity of ’Tongbai Jujube’ (Zizyphus Jujuba Mill.)during the Controlled Atmosphere (CA) storage (11% O2、0% CO2) were studied. The result showed that the amylase activity was not affected by CA storage, but PG activity was much lower than cold storage (CK). The PPO activity of CA storage was higher CK, which means has the possibility of inducing pulp brown. The activity of SOD, POD and CAT were preserved at high level, so that CA storage could prolong the storage period.
