At present, China is the world’s largest apple producer. After being picked, apples rely on its own nutrients to maintain life activities, and with the consumption of energy, the freshness will gradually decrease. Nowadays, the storage and preservation awareness, facilities and methods of the apple processing industry and households are weak and lacking. Apples are prone to decay and deterioration, which seriously affects the flavor, nutritional value and food safety. This paper studies the artificial intelligence recognition technology based on sensors array apple freshness characteristics. The main research contents include: artificial intelligence odor recognition theory research and construction of sensor array information acquisition system. Combined with theoretical experiments, the research establishes apple odor characteristic parameter evaluation model, uses dielectric features, odor recognition technology and node location information to achieve apple freshness artificial intelligence recognition. This project has important significance in both theoretical research and practical application.
