壳聚糖/H2O2雾化处理对伽师瓜贮藏品质的影响
Effect of chitosan/H2O2 treatment on storage quality of Jiashi melon
摘要
Abstract
Preservation effect of chitosan,H2O2 treatment on long-term storage of Jiashi melon was studied.Based on the previous research,1%chitosan coating and 6%H2O2 nano atomization treatment was applied to Jiashi melon and stored at(2±0.5)℃.The quality changes during the storage were analyzed using principal component analysis.The results showed that preservation treatments could maintain postharvest quality of Jiashi melon,chitosan/H2O2 composite treatment had significantly delayed fruit decay index(0.105%),inhibited loss in hardness(4.21 kg/cm2)and weight(4.90%),reduced consumption of SSC(11.5%)and ASA(15.44%)substances,prevented cell membrane damage,and induced antioxidant enzyme activity.PCA analysis obtained two principal components,with cumulative contribution of 93.6%.Among them,weight loss rate,conductivity,and CAT activity were key indicators in the preservation of Jiashi melon.Overall analysis showed that combined treatment of 1%chitosan coating and 6%H2O2 nano atomization had significant preservation effect on Jiashi melon,and was superior to a single treatment.The study provides theoretical guidance for long-term preservation of Jiashi melon.关键词
