摘要
以金针菇为原料,研究壳聚糖、水杨酸、苯并噻重氮、茉莉酸甲酯4种抗性诱导剂对采后金针菇抗氧化酶系统的影响.结果表明:4种抗性诱导剂处理金针菇后,金针菇贮藏期间过氧化物酶(POD)、过氧化氢酶(CAT)、超氧化物歧化酶(SOD)活性在不同时期高于对照组,提高了金针菇清除活性氧自由基的能力,维持了机体活性氧代谢的平衡.同时,实验得出壳聚糖、水杨酸、苯并噻重氮、茉莉酸甲酯的最佳处理浓度分别为0.75g/L,0.5mmol/L,0.75mmol/L,100μmol/L,为金针菇的贮藏保鲜提供了数据参考.
In order to provide data reference for the storage and preservation of Enoki mushroom ( Flammulina velutipes ),an experiment was made in which harvested F. velutipes was treated with chitosan,salicylic acid,benzothiazole and methyl jasmonate to investigate the effects of the four resistance inducers on the antioxidant enzyme system in F. velutipes.The results indicated that all the four resistance inducers enhanced the activity of POD,CAT and SOD in F. velutipes over the control group,thus improving the ability of the mushroom to remove reactive oxygen free radicals and maintaining the balance of active oxygen metabolism.The optimal treatment concentration of chitosan,salicylic acid,benzothiazide and methyl jasmonate was 0.75 g/L,0.5 mmol/L,0.75 mmol/L and 100 μmol/L,respectively.
