通过溶液共混法制备了ε-聚赖氨酸的浓度分别为0%、5%和10%的壳聚糖/ε-聚赖氨酸涂液及复合膜,对其抑菌性进行了表征,并将壳聚糖/ε-聚赖氨酸涂液应用于龙眼,考察其对龙眼的保鲜性能影响。结果发现,壳聚糖/ε-聚赖氨酸膜具有优异的抑菌性,其抑菌性随着ε-聚赖氨酸含量的增加而增强。随着ε-聚赖氨酸含量的增加,壳聚糖/ε-聚赖氨酸涂液能更好地抑制龙眼失重率和果皮褐变率的上升,延缓可溶性固形物的减少,从而提高了龙眼的好果率。在本实验中,ε-聚赖氨酸浓度为10%的壳聚糖/ε-聚赖氨酸涂液对龙眼的保鲜效果最好。

The chitosan/ε-polylysine composite solutions and films the ε-polylysine concentration of 0%,5% and 10% respectively were prepared by solution blending. The antibacterial activity of the chitosan/ε-polylysine composite films was characterized and the effect of chitosan/ε-polylysine coating solutions on longan fruit was also investigated. The results showed that the antibacterial performance of chitosan/ε-polylysine films was strong and enhanced with the increase of ε-polylysine content. It was found that the chitosan/ε-polylysine coating...
