Traditionally, food packaging is used to enhance food quality and provide consumers with product descriptions. As a new type of food packaging technology, the new generation of intelligent packaging can sensitively sense changes in the environmental atmosphere of stored food, so as to make a visual response to monitor the quality and freshness of food. This work summarizes the latest research on the development, properties and applications of natural polysaccharide-based smart food packaging materials. Firstly, the intelligent packaging system and polysaccharide-based intelligent packaging are summarized, and several representative polysaccharides are introduced. Secondly, different sensing methods that can be used to detect changes in food properties, such as those based on changes in time, temperature, humidity, oxygen levels, pH, chemical composition, or microbial contamination, are described. Then, the application of polysaccharide-based intelligent packaging materials in the food industry is discussed. Finally, the challenges and future directions of polysaccharide-based intelligent food packaging are discussed.
