摘要
以"豇豆"为试材,探究不同保鲜膜包装处理对豇豆的保鲜效果。结果表明:室温下贮藏,CO_2高渗透性保鲜膜和纳米膜处理均能有效延缓失重率的升高,抑制可溶性固形物(TSS)、维生素C和可溶性蛋白质含量的降低,抑制丙二醛(MDA)含量的增加,维持细胞膜的完整性,同时延缓了过氧化物酶(POD)活性的升高,增强了过氧化氢酶(CAT)活性,从而延缓了豇豆的衰老和活性氧的损伤。其中,CO_2高渗透性保鲜膜的保鲜效果较佳。
The cowpea was used as test material,to study the effect of different fresh film treatments on the preservation of cowpea.The results showed that high CO_2 permeability film and nano-film treatments both effectively delayed the increase of weight loss,inhibited the decrease of TSS,vitamin C and soluble protein contents,suppressed the accumulation of MDA content and maintained the membrane integrity,meanwhile,delayed the increase of POD activity and enhanced the CAT activity,therefore delayed the senescence and ROS damage of cowpea.Whereby,the treatment of high CO_2 permeability film was better.
