Coordination-Driven Nanoarchitectures for Smart Packaging Strategies in Poultry Preservation.

The poultry industry faces major challenges in preserving meat freshness and safety due to high water activity, rapid microbial growth, and oxidative spoilage. Traditional methods such as vacuum sealing and antioxidants are insufficient, as they cannot effectively suppress anaerobic pathogens and lack real-time freshness assessment. This review introduces a transformative strategy that applies coordination chemistry to design multifunctional nanomaterials for poultry preservation. Dynamic metal-ligand interactions-including redox-active centers, stimuli-responsive bonds, and host-guest adsorption-allow precise antibacterial control through 4 mechanisms: ligand-regulated ion release, reactive oxygen species (ROS) generation, coordination-triggered antimicrobial delivery, and electrostatic membrane disruption. In addition, freshness can be monitored by biomarker-specific coordination responses, such as nanoparticle aggregation for optical signals or MOF (metal-organic framework)-based volatile amine capture for colorimetric and electrochemical detection. Integration with oxygen scavengers, humidity regulators, and pH-responsive systems optimizes the packaging environment. Coupling with digital technologies further enables intelligent platforms for autonomous quality validation and supply chain transparency. This approach connects molecular-scale coordination principles with engineering practice while addressing biodegradability, environmental resilience, and scalability to reduce waste and achieve sustainable poultry preservation.
