摘要
本文以草莓为实验对象,配置不同浓度的茶多酚-壳聚糖复合涂膜剂进行涂膜处理后放置5℃冷库中进行保鲜贮藏实验,以寻找最佳浓度的复合涂膜保鲜液。在贮藏期间,从感官、失重率、色差值、腐烂率、硬度五个方面的变化评价草莓的品质。实验结果表明:在茶多酚-壳聚糖复合涂膜液中,当壳聚糖浓度为1.5%,茶多酚浓度为1.0%时,草莓的保鲜效果最好。
In order to find the best concentration of tea polyphenol-chitosan composite coating solution for fresh-keeping,strawberry was treated with different concentration of tea polyphenol-chitosan composite coating solution and stored in cold storage at 5℃.During storage,the quality of strawberry was evaluated from five aspects:sense organ,weight loss rate,color difference,rot rate and hardness.The results showed that the fresh-keeping effect of strawberry was best when the concentration of chitosan was 1.5%and the concentration of tea polyphenol was 1.0%.
