Bacterial contamination reduces the shelf-life of foods and presents serious risks to human health. Nanotechnology provides the opportunity for the development of new antibacterial agents. Nano-inorganic metal oxides have shown the potential to reduce bacterial contamination of foods. When the particle size of materials decreases from the micrometre to the nanometre range, nano-functional properties such as diffusivity, mechanical strength, chemical reactivity and biological properties are improved. Significantly, ZnO has been used in many applications with particular success. Many studies have shown that ZnO nanoparticles have enhanced antibacterial activity. This review discusses the main synthetic methods, antibacterial activity, antibacterial mechanisms and food applications of ZnO nanoparticles.
细菌污染会缩短食品的保质期，并对人类健康构成严重威胁。纳米技术为开发新型抗菌剂提供了机会。纳米无机金属氧化物已显示出降低食品细菌污染的潜力。当材料的粒径从微米减小到纳米范围时，扩散性、机械强度、化学反应性和生物特性等纳米功能特性得到改善。值得注意的是，氧化锌已在许多应用中得到了广泛应用，取得了特别的成功。许多研究表明，氧化锌纳米颗粒具有增强的抗菌活性。本文综述了氧化锌纳米颗粒的主要合成方法、抗菌活性、抗菌机制及在食品中的应用。
