【摘要】 使用壳聚糖配制的涂膜液处理油豆角,通过测定涂膜的油豆角在贮藏期间呼吸强度、PPO、POD、MDA的变化,探讨油豆角在贮藏期间的生理变化规律。结果表明,涂膜处理后能推迟油豆角呼吸高峰的到来;同时,在贮藏期间,涂膜油豆角的呼吸强度、PPO、POD、MDA与对照组相比都有所降低。更多还原

【Abstract】 Snap beans were coated with chitosan edible coatings, and then the respiration intensity,the activity of polyphenol oxidase and peroxidase,and the content of malondialdehyde were detected during the storage and the physiology change of snap beans were discussed.The result showed that the breath pinnacle of coated snap beans were postponed,the respiration intensity,the activity of polyphenol oxidase and peroxidase,and the content of malondialdehyde of snap beans treated were lower than that of control during storage.更多还原
