摘要: The development of sustainable and functional food packaging is essential for mitigating food waste. In this study, quercetin nanocrystals (QNs) are synthesized and utilized to improve functionality of chitosan/ polyvinyl alcohol (PC) films. Molecular dynamics simulations and experimental characterizations reveal that the self-assembly of QNs is primarily driven by supramolecular interactions. QNs exhibit good compatibility with PC films, acting both as a nanofiller to improve mechanical properties (tensile strength of 49.68 MPa and elongation at break of 176.02 %) and as an active agent to impart antioxidant properties (fourfold increase compared to plain PC film). Additionally, QNs enhance the thermal stability, UV-blocking capability, and water vapor barrier properties of the PC films. More importantly, the QNs-reinforced PC films significantly extend the shelf life of fresh meat to 11 days. This work provides an effective strategy for fabricating eco-friendly and functional food packaging materials, demonstrating great potential for application in food preservation.
