摘要

二氧化氯（ClO2）在食品保鲜方面的应用前景广阔。然而，大规模生产可控释放的 ClO2 薄膜面临着挑战。本研究以聚乙烯醇（PVA）为壁材，通过喷雾干燥法成功制备了亚氯酸钠微胶囊（Micro-SC）。此外，还利用熔融挤出法大规模制备了温湿度双响应的 ClO2 控释薄膜（Micro-SC@EVA）。该薄膜可在水蒸气的触发下释放 ClO2 达 36 天。随着微胶囊比例从 4% 增加到 8%，抗菌效果明显增强。Micro-SC@EVA 薄膜降低了草莓的总存活数和重量损失，抑制了乙烯的产生，与对照组相比，在 25 °C 下的保质期延长了 150%。应用评估结果表明，大规模制备 ClO2 控释薄膜的新方法对食品包装具有重要意义。

Large-scale dual-responsive ClO2 controlled-release film for strawberry preservation

Chlorine dioxide (ClO₂) exhibits promising potential for the application in food preservation. However, the large-scale production of controlled-release ClO₂ films faces challenges. The sodium chlorite microcapsules (Micro-SC) were successfully prepared in this study using polyvinyl alcohol (PVA) as the wall material through the spray drying method. Furthermore, A large-scale preparation of temperature and humidity dual-responsive ClO₂ controlled-release films (Micro-SC@EVA) was achieved using melt extrusion. The film could release ClO₂ triggered by water vapor for 36 days. The antibacterial effects were significantly enhanced with the increase of microcapsule ratio from 4 % to 8 %. The Micro-SC@EVA film reduced the total viable count and wight loss of strawberries, inhibits ethylene production, and extended the shelf life of by 150 % compared with the control group at 25 °C. The application evaluation results show that the novel approach for the large-scale preparation of ClO₂ controlled-release film holds significant implications for food packaging.
