This study developed an innovative nano-biohybrid active coating system based on rosemary extract-functionalized zinc oxide nanoparticles (RE-ZnO NPs) reinforced sodium alginate for advanced poultry preservation. The synthesized zinc oxide nanobiocomposites exhibited a hexagonal wurtzite structure with excellent crystallinity and an average size of 28 ± 3 nm. Phyto-functionalization with rosemary extract significantly enhanced antimicrobial efficacy, reducing MIC values by 45% against Staphylococcus aureus and 38% against Escherichia coli O157:H7 compared to unmodified nanoparticles. The optimized coating demonstrated exceptional multifunctional food preservation capabilities, achieving microbial reductions of 2.7-2.9 log CFU/g while maintaining TBARS values at 0.38 mg MDA/kg and superior color stability (ΔE = 3.87) during 12-day refrigerated storage. This sustainable active packaging technology represents a significant advancement in food preservation, combining green nanotechnology with natural bioactive compounds to effectively extend shelf life while addressing both microbial and oxidative spoilage mechanisms simultaneously. The research provides a comprehensive solution for reducing food waste and enhancing food safety through intelligent packaging design.
