金属有机框架材料载体系统在食品抗菌包装中的应用

目的 综述金属有机框架材料(Metal-organic frameworks，MOFs)作为载体系统在食品抗菌包装领域的研究现状和应用进展，以期为MOFs类抗菌包装材料的研发和应用提供参考。方法 介绍MOFs的基本概念及分类，概述MOFs的制备方法(加热法、机械法和电化学法等)，总结归纳近年来MOFs作为载体系统在无机抗菌剂、有机抗菌剂和天然抗菌剂领域的应用，并讨论MOFs作为载体系统的机遇和挑战。结论 MOFs作为一种有机与无机相结合的多孔性复合材料，不仅可有效封装抗菌剂，实现缓释和控释，且将MOFs复合材料作为高分子填料可提高其抗菌性能、力学性能和抗紫外线性能等，因此在制备高效、安全的食品抗菌包装方面具有巨大潜力。

Application of Metal-organic Frameworks as Carrier System in Food Antibacterial Packaging

The work aims to review the research status and application progress of metal-organic frameworks (MOFs) as carrier systems in the field of food antibacterial packaging, so as to provide reference for the development and application of MOFs antibacterial packaging materials. Firstly, the basic concepts and classification of MOFs were introduced. Secondly, the preparation methods of MOFs (heating method, mechanical method and electrochemical method) were analyzed. Then, the applications of MOFs as carrier systems in the fields of inorganic antibacterial agents, organic antibacterial agents and natural antibacterial agents in recent years were summarized. Finally, the opportunities and challenges of MOFs as carrier systems were discussed. In general, as a porous composite material combining organic and inorganic materials, MOFs can not only effectively encapsulate antibacterial agents to achieve sustained release and controlled release, but also improve their antibacterial properties, mechanical properties and UV resistance when used as polymer fillers. Therefore, MOFs have great potential in the preparation of efficient and safe food antibacterial packaging.
