Metal–organic frameworks (MOFs)-based materials in food packaging: a review

Food safety is an important issue related to the life and health of all people, and food packaging can effectually protect food from surface damage, mildew, rot, etc., while ensuring food quality to extend the shelf life, effectively preventing food safety problems. Metal–organic frameworks (MOFs) are functional materials with special physical and chemical properties, such as a high specific surface area, high porosity and adjustable structure, which can be designed and adjusted according to the characteristics of different food packaging materials, so they have significant application prospects in food packaging. This review systematically introduced the types and properties of MOFs materials, summarized the methods to synthesize MOFs, and discussed the application progress of MOFs in food packaging by evaluating the safety of MOFs. Further, the potential uses of MOFs in food packaging applications were explored. This review may provide systematic insight into the use of MOFs for food packaging and explore new ideas.
