Abstract

The work aims to discuss the research progress and current regulatory situation of smart active materials under the background that research on smart active materials is increasingly widespread both in China and abroad, so as to provide a theoretical basis for promoting the application of smart active material. This article systematically reviewed the current research progress of smart active materials for food contact both domestically and internationally, focusing on summarizing research advancements in pH-responsive, temperature-responsive smart materials, as well as antibacterial and antioxidant active materials and products. It discussed the current regulatory status of these smart active materials for food contact and further explored the challenges and opportunities they face. Currently, significant advancements have been made in the research of smart active materials for food contact, which can effectively monitor food status and extend its shelf life. However, in practical applications, there are numerous challenges such as high production costs and uncertain safety. In the future, a series of research will be conducted on the safety assessment of smart active materials and the simplification of production processes to achieve their industrial application.
