Functionalized polyvinyl alcohol nanofibers with visible light-triggered antibacterial and ethylene scavenging capabilities for food packaging
In this study, the sulfonated cobalt phthalocyanine-titanium dioxide P25 (CoPcTs-P25) nanoparticles were prepared by in situ synthesis and the samples were characterized using Fourier transform infrared spectroscopy, X-ray diffraction and UV–Vis spectroscopy. Biodegradable polyvinyl alcohol was selected as the backing material and CoPcTs-P25 was added as a visible-light ethylene scavenger and bacterial inhibitor, and PVA-CA@CoPcTs-P25 nanofiber films were prepared by electrospinning. In addition, the effects on ethylene degradation, bacterial survival and biocompatibility of the composite nanofiber were also evaluated. The photocatalytic degradation efficiency of [email protected]%CoPcTs-P25 nanofibers for ethylene could reach 13.92% under visible light irradiation for 6 h. The nanofiber exhibited excellent antibacterial activity against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli), with a remarkable inhibition rate of over 90%. This bifunctional nanofiber demonstrated a new strategy for developing packaging materials and provided a broad prospect in fruits and vegetables preservation.
期刊介绍：
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.
