AI Technical Summary

Technical Problem

Existing polymer-based packaging films have poor mechanical properties, weak antibacterial and barrier properties, and cannot effectively extend the shelf life of food.

Method used

A gelatin-ZnO/chitosan-high internal phase emulsion bilayer membrane was prepared by loading tea tree oil high internal phase emulsion into the inner layer and using a chitosan-gelatin composite membrane on the outer layer. The antioxidant and antibacterial properties of tea tree oil and the barrier properties of nano-ZnO were utilized to form a stable bilayer membrane structure.

Benefits of technology

It achieves effective food preservation, reduces water vapor transmission rate, improves light blocking performance, and has excellent antioxidant and antibacterial capabilities, which can significantly extend the shelf life of food.
