水溶性壳聚糖涂膜处理对采后绿芦笋贮藏品质的影响
Effect of water-soluble chitosan coatings on postharvest green asparagus quality
摘要
Abstract
The quality of 0.50% water-soluble chitosan (WSC) and carboxymethyl chitosan (CMC) coatings on postharvest green asparagus which were stored at 2℃ was investigated.Base on the data of sensory evaluation, weight loss percentage, the contents of ascorbic acid, chlorophyll, malonaldehyde ( MDA) , total phenolic and polyphenolox-idase (PPO) , peroxidase (POD) , super oxygen dehydrogenises (SOD) activity testing, both 0.50% WSC and CMC treatments could dramatically retard the decrease of weight loss, firmness, the loss of chlorophyll and ascorbic acid during the storage.Moreover, 0.50% CMC treatment not only could keep the total phenolics content, but restrain the changes of PPO, POD, and SOD activity, presenting better quality of asparagus than the control during the cold storage , and prolong the shelf life of postharvest green asparagus to 35 days.关键词
