柑橘为在全球广泛生产的水果之一，容易腐败，采用传统的包装薄膜已不能完全阻挡其被致病致腐微生物侵染，而且不可降解包装薄膜会对地球生态环境造成严重危害。针对上述问题，本研究利用可降解材料成功制备聚对苯二甲酸-己二酸丁二酯/聚乳酸/姜黄素(PBAT/PLA/Cur)复合薄膜。结果表明，Cur复合薄膜对指状青霉、沙门氏菌和单增李斯特菌的光动力杀菌效果达到99%。通过扫描电镜、X射线衍射、傅里叶变换红外光谱、差示扫描量热法、力学性能等测试，发现Cur复合薄膜具有均匀的微孔结构和优异的拉伸性能，PBAT/PLA/Cur，PBAT/PLA/0.25%Cur，PBAT/PLA/0.5%Cur膜的平均孔径分别为(222±64)，(275±83)，(356±89)nm，薄膜拉伸强度可达(7.35±2.1)MPa，断裂伸长率达(333±19)%。此外，Cur复合薄膜包裹的柑橘果实水分流失率低，接种指状青霉的柑橘覆膜后，腐败率降低60%，货架期可延长4 d。结论:Cur复合薄膜可以有效保持柑橘品质，提高果实的贮藏抗性，在柑橘保鲜领域具有广阔的应用前景。

Citrus fruit， one of the most widely cultivated fruits globally， is highly perishable. Traditional packaging films are no longer sufficient to fully prevent its infection by pathogenic and spoilage microorganisms. Furthermore， non-biodegradable packaging films pose a serious threat to the Earth's ecosystem. To solve the above problems， this study successfully prepared polybutylene adipate terephthalate /polylactic acid/ curcumin (PBAT/PLA/Cur) composite films using degradable materials. The results showed that the photodynamic bactericidal effect of the Cur composite film against Penicillium digitatum， Salmonella Typhimurium and Listeria monocytogenes reached 99%. By scanning electron microscopy (SEM)， X-ray diffraction (XRD)， Fourier transform infrared spectroscopy (FTIR)， differential scanning calorimetry (DSC)， mechanical properties and other tests， it was found that the Cur composite film has a uniform microporous structure and excellent tensile properties. The average pore sizes of PBAT/PLA/0.5%Cur films were (222±64)， (275±83)， (356±89) nm， respectively. The tensile strength of PBAT/PLA/0.5% CUR films could reach (7.35±2.1) MPa， and the elongation at break could reach (333±19)%. In addition， the CUR-compound thin-wrapped citrus fruit has a low water loss rate， the spoilage rate of the citrus after inoculation with P. digitatum is reduced by 60%， and the shelf life can be extended for 3 days. In summary， the Cur composite film can effectively maintain the quality of citrus， improve the storage resistance of citrus fruit， and have broad application prospects in the field of citrus preservation.
