负载碳量子点的壳聚糖/谷朊蛋白复合膜在鲜切黄瓜保鲜中的应用

Effect of Chitosan/Gluten Protein Composite Film Loaded with Carbon Dots in Fresh-Cut Cucumber

为了提高鲜切黄瓜片的保鲜效果,本研究以厨余垃圾——香蕉皮作为碳量子点的合成原料,添加到壳聚糖/谷朊蛋白的成膜材料中,制备成负载碳量子点的壳聚糖/谷朊蛋白复合膜用于鲜切黄瓜保鲜的研究。结果表明,负载碳量子点的壳聚糖/谷朊蛋白复合膜表现出很好的保鲜效果,能够明显降低鲜切黄瓜片的腐烂率和失水率,延缓糖、酸的转化,减少维生素C的损失。研究表明,负载碳量子点的壳聚糖/谷朊蛋白复合膜能进一步提高保鲜效果,为研发新的果蔬保鲜技术和材料提供理论基础。

In order to improve the fresh-keeping effects of cucumber slices,kitchen waste--banana peels were taken as raw material of carbon dots and added to chitosan/gluten film.In this study,the effect of preservation of fresh cucumber slices covered with this kind composite film were done.The results showed that the chitosan/gluten composite film loaded with carbon dots showed good preservation effect,which could significantly reduce the decay rate and water loss rate of fresh cut cucumber slices,and delayed the conversion of sugar and acid and the loss of VC.Therefore,this study also provided a theoretical basis for the development of new preservation technology for fresh-keeping offruits and vegetables.
