Development of chitosan/polycaprolactone-thymol Janus films with directional transport and antibacterial properties for meat preservation.

Reducing contamination from percolate is critical to the preservation of foods with high water content, such as pork. This study aims to develop a novel active packaging material for meat preservation by precisely controlled dual-channel one-step electrospinning. Compared to traditional strategies of preparing Janus films, this method allows for greater flexibility and efficiency.

Thymol incorporation within chitosan/polyethylene oxide nanofibers by concurrent coaxial electrospinning and in-situ crosslinking from core-out for active antibacterial packaging.

Active packaging systems that are sustainable and capable of delivering antimicrobial agents are in demand in food industry. In this work, Thymol (Thy) was encapsulated into Polyethylene oxide (PEO)/Chitosan (CS) to form core-shell nanofibers via coaxial electrospinning. Various dose of the crosslinker-genipin (GP) were encapsulated into the core layer to achieve in-situ etching crosslink with the CS of shell layer during the electrospinning process.

Fabrication of cellulose acetate/gelatin-eugenol core-shell structured nanofiber films for active packaging materials.

In this study, novel active materials based on cellulose acetate (CA) and gelatin (Gel) for the release of eugenol (Eg) were developed by fabricating CA/Gel-Eg core-shell structured nanofiber films using the coaxial electrospinning technique. These electrospun nanofibers were coated with a CA shell, which has excellent water stability. Eg was encapsulated on the core part of the Gel.
