摘要
[目的]探索硒在大果山楂贮藏保鲜中的应用,并为开发富硒大果山楂提供理论依据.[方法]以富硒大果山楂为原料,对其果实中有关酶活性及贮藏品质进行研究.[结果]富硒大果山楂果实中过氧化物酶(POD)和多酚氧化酶(PPO)的活性比对照组分别降低了49.2%和37.5%,超氧化物歧化酶(SOD)和过氧化氢酶(CAT)的活性比对照组分别增加了16.7%和33.5%.大果山楂果实硬度为25.29 N/cm2,维生素C的含量为1 186.50 mg/kg,可溶性总糖的含量为144.00 g/kg,可溶性固形物的含量为16.60%,较对照组分别增加了13.2%、9.5%、29.0%、3.7%.[结论]硒能延缓大果山楂果实的成熟衰老,改善其品质.
Abstract
[Objective]To explore application of selenium in storage and preservation of M. domeri, and provide theoretical basis for development of selenium-enriched M. domeri. [Method]The activity of associated enzyme and storage quality were studied with selenium-enriched M. domeri as raw material. [Result]The results indicated that the POD and PPO activity reduced by 49.2% and 37.5% compared with ordinary M. domeri, the SOD and CAT activity increased by 16.7% and 33.5% compared with ordinary M. domeri. The hardness, Vc, total soluble sugar, soluble solids were 25.29 N/cm2, 1 186.50 mg/kg, 144.00 g/kg, 16.60%, respectively, increased by 13.2%, 9.5%, 29.0%, 3.7% compared with ordinary M. domeri. [Conclusion]Selenium could delay senescence and improve the quality of M. domeri.
