The work aims to introduce, classify and summarize the applications of intelligent sensor technology in intelligent packaging fruit and vegetable monitoring, so as to provide the basis and assistance for intelligent monitoring of fruit and vegetable shelf life and promote the practical application of sensor technology in the field of intelligent packaging of fruits and vegetables. The intelligent sensors of moisture-sensitive, gas-sensitive and microbial detection types were introduced, and the application of intelligent technologies such as NFC/RFID in the shelf life monitoring of fruit and vegetable packaging was analyzed. Compared with traditional packaging methods, this kind of intelligent packaging combined with the current development trend of the Internet, brought more convenience to people's life. Intelligent sensor labels play an important role in the intelligent monitoring of food products such as fruits and vegetables, and can quickly monitor the freshness of food by connecting to terminals such as smartphones. In recent years, the research and development of packaging materials have been diversified, such as multi-composite nanomaterials, metal-organic framework materials, etc. Optimizing packaging sensing materials can better utilize the advantages of intelligent packaging labels in intelligent packaging of fruits and vegetables.
