| Summary: | The existing traditional active preservation packaging has disadvantages such as low porosity and poor air permeability, so the fabrication of nano-scale packaging materials that can release slowly and retain freshness is a hot research topic in the field of storage and logistics of postharvest fruits and vegetables. In this study, polycaprolactone (PCL) nanofiber membranes loaded by thymol (THY) were prepared by the solution blow spinning technique, and the properties of THY/PCL nanofiber membranes were evaluated by material characterization and bacterial inhibition experiments. The results showed that the THY/PCL nanofiber membranes had lower crystallinity and increased thermal stability, while their water vapor permeable properties, surface hydrophobicity, and mechanical properties were not affected. In addition, the THY/PCL nanofiber membranes showed good antibacterial activity against Escherichia coli and Staphylococcus aureus, demonstrating a good application prospect in the field of postharvest preservation of fruits and vegetables. |
