为了提高香蕉采后的品质，开发了具有生物活性和电化学写入特性的活性琼脂（AG）双层膜。 AG下层加入红萝卜提取物（RRE）和印楝精油（NEO），增强了薄膜的抗氧化和抗菌能力。在AG上层中添加TiO2，有效提高了双层膜的阻隔性能和机械性能、总花青素和NEO含量的保留率。多色图案成功写入含有 RRE 的双层薄膜上。根据香蕉果实外观、衰老斑点症状、微生物分析、失重和硬度等表征，AG-TiO2+AG-RRE-NEO双层膜在香蕉果实贮藏期间表现出最佳的保鲜效果。因此，AG-TiO2+AG-RRE-NEO双层膜有望成为香蕉保鲜的多功能包装材料。
Active agar (AG) bilayer films with bioactive capability and electrochemical writing property were developed for improving the postharvest quality of the banana. The antioxidant and antimicrobial capacity of the films were enhanced with the incorporation of red radish extract (RRE) and neem essential oil (NEO) into AG lower layer. The barrier and mechanical properties, retention of total anthocyanin and NEO content in the bilayer films were effectively improved with addition of TiO2into the AG upper layer. Multicolor patterns were successfully written on the bilayer film containing RRE. The AG-TiO2+AG-RRE-NEO bilayer film exhibited the optimal preservations on banana fruits during the storage period, based on the characterization by fruits appearance, senescent spotting symptom, microbial analysis, weight loss and firmness. Thus, the AG-TiO2+AG-RRE-NEO bilayer film was expected to be a multifunction packaging material for banana preservation.
