The functional gelatin/curcumin composite film was prepared using an emulsifier, sodium dodecyl sulfate (SDS). The composite films were characterized using field emission scanning electron microscopy (FE-SEM) and Fourier transform infrared spectroscopy (FTIR). The FE-SEM test results showed that curcumin was evenly distributed in the gelatin polymer matrix to form a flexible composite film with a smooth surface. The addition of 1.5 % of curcumin improved the UV blocking effect by more than 99 % at a loss of 5.7 % of transparency compared to neat gelatin films. The addition of curcumin (up to 1 wt%) significantly improved mechanical and water vapor barrier properties. Also, the gelatin/curcumin composite films exhibited remarkable antimicrobial activity against foodborne pathogenic bacteria, E. coli and L. monocytogenes, and showed strong antioxidant activity comparable to ascorbic acid. Antibacterial and antioxidant gelatin/curcumin composite films with improved UV protection, water vapor barrier and mechanical properties have high potential in active food packaging applications.

用于活性食品包装的抗菌和抗氧化剂明胶/姜黄素复合膜的制备。
使用乳化剂十二烷基硫酸钠（SDS）制备功能性明胶/姜黄素复合膜。使用场发射扫描电子显微镜（FE-SEM）和傅立叶变换红外光谱（FTIR）对复合膜进行表征。FE-SEM测试结果表明姜黄素均匀地分布在明胶聚合物基质中，形成具有光滑表面的柔性复合膜。与纯明胶薄膜相比，添加1.5％的姜黄素可将紫外线阻隔效果提高99％以上，而透明度损失5.7％。姜黄素的添加（至多1 wt％）显着改善了机械和水蒸气阻隔性能。而且，明胶/姜黄素复合膜对食源性致病菌，大肠杆菌和单核细胞增生李斯特菌具有显着的抗菌活性，并显示出与抗坏血酸相当的强抗氧化活性。具有改进的紫外线防护，水蒸气阻隔性和机械性能的抗菌和抗氧化剂明胶/姜黄素复合膜在活性食品包装应用中具有很高的潜力。
