Abstract: With the rapid development and deep integration of Internet of Things (IoT), artificial intelligence (AI), big data, and cloud computing technologies, smart homes are transitioning from single-product intelligence to a new stage of whole-scene intelligence. As the core hub of the smart kitchen and a key node in family health management, the value of smart refrigerators has far surpassed traditional refrigeration and preservation functions. Their core competitiveness is increasingly focused on the intelligence level of food management capabilities. However, the isolated development of food recognition technology alone does not support the vision of smart refrigerators as the “family health management hub.” By systematically exploring the evolution of food management functions in smart refrigerators, this study analyzes the core development trends from technical, functional, and ecological dimensions, aiming to provide new directions and insights for the overall development of the smart refrigerator industry.
