Research Progress in the Preparation of Nanocellulose-Based Composite Films and Their Application in Food Preservation

It is a worldwide technical problem to avoid the waste of food resources caused by storage conditions not meeting the requirements. On this basis, the preparation and application of green and environmentally friendly degradable nanocellulose-based antimicrobial films have received widespread attention. This paper systematically introduces the common preparation methods of nanocellulose-based composite films and the latest progress in their applications in fruit and meat preservation. The mechanism of action of nanocellulose-based composite films in food preservation is described, and their advantages such as high mechanical strength, degradability, and biocompatibility over traditional antimicrobial films are analyzed. Moreover, the application potential of nanocellulose-based films in food preservation is discussed.
