Abstract
A novel hybrid nanostructure was synthesized by functionalizing an iron-based metal-organic framework (MOF) with carbon quantum dots (CD@MOF). The developed CD@MOF had an octahedral crystal structure and exhibited favorable antioxidant, antifungal, and antibacterial activities. MOF and CD@MOF particles are incorporated into agar/gelatin (Agar/Gel) blend polymers. The compatibility and dispersion of CD@MOF in the polymer were confirmed through FTIR, XPS, and SEM analysis. The conjugation of MOF with CDs enriched in active edges resulted in superb antioxidant (71.9 % DPPH and 100 % ABTS) and antibacterial activities. The addition of CD@MOF increased the tensile strength and gas (water vapor and oxygen) barrier and UV barrier (100 % UV blocking) properties of the film. In addition, tomato fruits were packaged with fabricated films and stored at 4 ℃ for 24 days, and quality changes were investigated. The experimental outcomes indicated the effective preservation performance of the Agar/Gel/CD@MOF films on packaged tomatoes.

Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
