Research on Application of Nanomaterials in Food Packaging Design

Nowadays, food packaging is an indispensable part of food processing. In the process of food processing, food packaging can protect food from external biological, chemical and physical factors, and ensure the stability of food performance. With the increasing awareness of food safety and environmental protection, people pay more attention to the selection of packaging materials. Therefore, the application development of nanomaterials is increasing year by year. During the processing of food packaging materials, the addition of some nano-materials can improve the preservation effect and texture of the packaging materials to a certain extent, and can even effectively protect the nutritional components in food. This has great benefits for people's health. However, there are some safety problems in the application of nanomaterials. This paper summarizes the applications of nanomaterials in food packaging, the main detection techniques of nanomaterials, the problems of nanomaterials in food packaging, the safety evaluation of nanomaterials and the development of nanomaterials.
