Abstract

It is highly urgent to develop a simple and effective strategy to extend the shelf life of time-sensitive fruits, which are very susceptible to spoilage over time, resulting in considerable food waste. Herein, a biopolymer-based composite film with superior antibacterial and antioxidant properties was developed by introducing MXene and tannic acid into a chitosan network via hydrogen bonding and an electrostatic self-assembly method. The results show that the mechanical properties, water and heat resistance, antibacterial and antioxidant capabilities of the obtained Chitosan-Tannic acid/MXene film are significantly increased to meet the use of packaging film scenarios. The fruit preservation experiments also confirmed that the composite film can effectively extend the shelf life of bananas and grapes through its excellent water vapor and oxygen barrier. These desirable performances enable our newly designed composite film to be an effective and competitive packaging material to solve the fresh fruit preservation dilemma.
