“Metal-Organic Frameworks (MOFs) are hybrid materials with high porosity and tunable physical and chemical properties. Due to their properties, MOFs are utilized for different purposes in the food industry. Moreover, these materials display good biocompatibility and have not shown adverse reactions during testing.
The incorporation of MOFs into packaging materials can provide antimicrobial properties. For example, ZIF-8 MOF nanoparticles were tested in a chitosan-based polymer. According to the report, the material exhibited hydrophobicity and resistant mechanical properties. Keeping the optimal water content constant is essential to retain the freshness and avoid bacterial and fungal growth. The material containing the ZIF-8 MOF showed a 100% antibacterial performance against microorganisms like Staphylococcus aureus and Escherichia coli.
MOFs are versatile materials that can offer several properties such as:
- Antibacterial activity
- Ethylene removal
- Oxygen and water scavengers
- Invisible labeling
The application of MOFs materials in the food industry is not limited to packaging. They can be applied for the detection of toxic compounds, safety monitoring, and sanitation.”
