AI Technical Summary
Existing food packaging materials are insufficient to meet environmental protection requirements, disinfection and sterilization methods may leave safety hazards, active ingredients are not released well, and traditional processes are cumbersome and not conducive to industrial use. The method of releasing active ingredients by stimulating light requires high performance of the food preservation film.
Gelatin-based composite fiber membranes were prepared using electrospinning technology and combined with ultraviolet irradiation treatment. Oregano essential oil emulsions were stabilized using a gelatin-gum arabic composite emulsifier, and fiber membranes were formed by electrospinning. The active ingredients were released by ultraviolet light excitation.
It achieves stable release of active ingredients and efficient antibacterial and antioxidant effects, simplifies the process, meets environmental protection requirements, and is suitable for the preservation of chilled meat.
