目的 介绍纳米氧化锌在食品抗菌包装膜中的研究现状。方法 总结纳米氧化锌在包装膜材中的应用， 并指出当前研究的不足和未来研究趋势。结论 纳米 ZnO 的粒径、 形貌、 分散性、 活化程度、 添加量等对其在不同包装基材系统中的抗菌效果有很大的影响。纳米 ZnO 在不同包装基材中的迁移研究还不完善， 需要进一步研究其迁移机理， 预测其迁移模型。单一添加纳米ZnO的研究较多， 纳米ZnO与具有其他功能物质复合使用的研究较少， 而复合使用是未来纳米ZnO复合抗菌包装研究领域的重点。

This paper introduced the research status of nano zinc oxide used in the food antimicrobial composite packaging film. This paper summed up its development status, pointed out the research insufficiency and predicted the research trend in the future. Nano zinc oxide, as one of the important inorganic nano-sized metal antimicrobial agents, has been used in food antimicrobial composite packaging. Recent researches have found that the size, morphology, disperse uniformity, activation degree and concentration of nano zinc oxide have great influence on its antibacterial effect in different packaging systems. This paper summarized the recent researches on nano zinc oxide used in food packaging film, and pointed out that the study of ZnO migration in packaging film is incomplete, and more researches on the migration mechanism and the transport model are needed to predict the migration model. Researches on the combination use of two or more various functional agents are few and the application of composite agents will be the research focus in the future.
