The invention discloses a fresh commodity safety intelligent detection management system based on big data. The system comprises a commodity weight detection module, a package damage analysis module,an environmental parameter acquisition module, a parameter preprocessing module, an image acquisition and processing module, an image recognition and analysis module, a commodity parameter database, afreshness analysis module, a management server and a display terminal. According to the invention, a commodity comprehensive eating safety coefficient is evaluated by considering factors such as weight change, temperature change, humidity change, peculiar smell concentration, commodity color, volume and existence of scratches and mildew spots on the surface of the commodity, and analyzing a commodity package breakage coefficient, a temperature safety influence coefficient, a humidity safety influence coefficient, a peculiar smell influence coefficient and commodity freshness, reference is provided for later commodity storage, the commodity eating safety detection efficiency and accuracy are improved, a lot of manpower cost is reduced, and commodity safety is guaranteed.
