Abstract
The invention provides a system for managing food information based on an odor, which comprises a gas sensing module, a processing module, a blockchain module and a display module. The gas sensing module includes a colorimetric gas sensing chip reacting with odor molecules emitted by the food to form a coloring reaction and present a color image corresponding to the food. The processing module includes a conversion unit for converting the color image into identification information corresponding to the food. The blockchain module includes a plurality of nodes, and the plurality of nodes store identification information corresponding to the food. The display module includes an identification label corresponding to the identification information. Therefore, when the invention is applied to the blockchain technology, it can remove the doubt that the data on the chain can be falsified before the data is uploaded.
