The work aims to sysmetaically introduce the type and application status of gas sensors, so as to provide experience and reference for the application of gas sensors in different smart food packaging. The application research progress of gas sensors in smart packaging of fruits, vegetables, seafood, meat, etc. was reviewed and the limitations of the application of gas sensors in smart food packaging and the future development trends were analyzed. The current consumers’ increasing requirements for food safety and freshness determined the wide application of gas sensors and made them continue to develop in a safe, green, and pollution-free direction. The application of gas sensors in improving food safety and traceability has great potential and broad development prospects. The gas sensors can track and monitor the freshness of food during the shelf life, ensure food safety, and effectively promote the development of food packaging technology.
