Antimicrobial Fiber Film Sprayed with Low-Dose Ethyl Lauroyl Arginate for Postharvest Preservation of Strawberries.

CFU/mL, respectively. Furthermore, the PET-0.3% LAE fiber film effectively maintained strawberries freshness. At room temperature, the control group's shelf life was 3 days, while that of the PET-0.3% LAE group extended to 7 days, representing a 4-day extension compared with the Control group. This work provides a useful solution and a new viewpoint on active packaging, creating new opportunities to develop antimicrobial materials with improved performance and reduced agent usage. To prevent strawberry decay and effectively extend their shelf life, a low-dose, safe, and antimicrobial-enhanced composite fiber film was successfully prepared. Spraying a low dose of LAE onto the surface of electrospun PET fiber films not only enhanced the fiber's resistance to microorganisms but also effectively maintained strawberry freshness, extending the shelf life of strawberries by 4 days at room temperature. This study provides an important reference for the development of antimicrobial functionalized preservation packaging materials and opens up a new path for active packaging technologies.
