A novel active food packaging film was developed by casting a corn starch/tea polyphenol (TP)-loaded porous starch (PS, obtained by enzymatic hydrolysis) film forming solution, with the latter helping to regulate the slow release of TP. Results showed that PS had a favorable TP adsorption capacity, and the casted films had a homogeneous distribution of the formulation components. Likewise, the active films had good mechanical properties, UV barrier properties, thermal stability, and excellent antioxidant properties. The slow release of TP from the films was sustained, which is a desired characteristic for extending the protection afforded by the active film to the food under consideration.
一种新型的活性食品包装膜是通过浇铸玉米淀粉/茶多酚（TP）负载多孔淀粉（PS，通过酶解获得）成膜溶液来开发的，后者有助于调节 TP 的缓慢释放。结果表明，PS 对 TP 具有良好的吸附能力，并且浇铸的薄膜具有制剂成分的均匀分布。同样，活性薄膜具有良好的机械性能、紫外阻隔性能、热稳定性和优异的抗氧化性能。TP 从薄膜中的缓慢释放是持续的，这是延长活性薄膜对所考虑的食品提供的保护的理想特性。
