| 摘 要： | 不结球白菜采后贮藏过程中品质易发生变化。贮藏过程中采用二氧化碳气体（CO2）处理可以延缓采后不结球白菜的衰老进程。减少重要营养物质维生素C（Vc）、可溶性蛋白和叶绿素的损失；CO2处理可抑制过氧化氢清除酶系统中的过氧化氢酶（CAT）、抗坏血酸过氧化氢酶（APx）和过氧化物酶（POD）活力的升高。50％和100％的CO2处理都可延缓采后不结球白菜贮藏过程中品质的下降，而前者的处理效果要优于后者。在室温下（25℃）CO2处理对品质的保持效果较明显．4℃下CO2处理的效果并不明显；在CO2处理的条件下，不同温度处理对品质的改变也不明显，因此不结球白菜采后短期保存可单独采取CO2处理或低温贮藏的方法。

| Abstract: | The quality of non-heading cabbage tends to be deteriorated during postharvest storage. The results showed that carbon dioxide(CO2) treatment was able to retard senescence,and reduce the loss of vitamin C(Vc) ,soluble protein and chlorophyll. The activities of hydrogen peroxide scavenging enzyme system including catalase(CAT) ,ascorbic acid catalase(APX) and peroxidase(POD) were also inhibited by CO2 treatment. The descent of postharvest quality could be delayed by treatment with both 50% CO2 and 100% CO2,a... |
