▎ 摘 要
NOVELTY - System comprises: many fresh foods (10), where each of the fresh foods attached with product label (11), the product label includes thin film, code provided on thin film and associated with each of fresh foods, and colorimetric transducer array formed on thin film, the colorimetric transducer array comprises at least one sensing material for sensing fresh foods, each of sensing material undergoing chemical reaction with at least one metabolic molecule of each of fresh foods to change each of sensing material from an initial color to an indication color; an image capturing module (20), capturing an image, where the image comprises appearance of each of fresh foods, code and indication color; a processing module (30), providing real-time information associated with quality of each of fresh foods according to comparison result between image and database; and a classification module (40), receiving real-time information and classifying fresh foods according to real-time information. USE - The system is useful for managing and trading foods according to flavor of its (all claimed). ADVANTAGE - The system: utilizes coordinating the colorimetric transducer array with the image capturing module and the processing module, information associated with the quality of the fresh foods can be presented objectively, detailed and in real-time, allowing the fresh foods online traders to be capable of further classifying the fresh foods to achieve more stringent quality control and product differentiation, so that the commodities become more consistent; and conveys the quality information of the fresh foods to the consumers more accurately during transactions, reducing a cognitive gap of the quality of the fresh foods between the industry and the consumers, and increasing a satisfaction level of transactions. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (a) managing foods according to flavor of its; and (b) trading foods. DESCRIPTION OF DRAWING(S) - The figure illustrates functional block schematic diagram of system. Many fresh foods (10) Product label (11) Image capturing module (20) Processing module (30) Classification module (40)
