Food traceability system and method based on blockchain

Abstract

The invention discloses a food traceability system and method based on blockchain, and belongs to the technical field of food traceability. The system comprises an upper information supervision module, a growth information acquisition front end, a distribution service management module, a wholesale and retail management module, a public information query module and a warehouse logistics management module. The output ends of the growth information acquisition front end, the distribution service management module and the wholesale and retail management module are connected with the input end of the upper information supervision module; the output end of the upper information supervision module is connected with the input ends of the growth information acquisition front end, the distribution service management module, the wholesale and retail management module and the public information query module; the output end of the public information query module is connected with the input end of the upper information supervision module; the output end of the warehouse logistics management module is connected with the input end of the upper information supervision module.

Description

technical field [0001] The invention relates to the technical field of food traceability, in particular to a blockchain-based food traceability system and method. Background technique [0002] Food traceability refers to the food quality and safety traceability system, which is a food safety management system. By covering the upstream and downstream of the entire product industry chain, such as food production bases, food processing enterprises, and food terminal sales, information sharing is carried out to serve final consumers. Once there is a problem with the quality of food on the consumer side, they can conduct online inquiries through the traceability code on the food label to find out all the circulation information such as the food manufacturer, food origin, and specific farmers, and clarify the corresponding legal responsibilities of the party involved in the accident. [0003] With the improvement of people's living standards, meat food safety has increasingly beco...

Problems solved by technology

In the traceability of meat food, the patent CN201610329089.5 A kind of live animal natural breeding registration certification system and its method mentions that a third-party certification service system is established to provide farmers, cooperatives, slaughtering and meat food processing enterprises, and the government The management department and the final eater provide third-party search and certification services, which mainly use RFID information technology to calibrate the information, and then identify it through the QR code, one code per object, but in actual operation, because livestock need to be slaughtered, As a result, the original RFID information card loses its effectiveness after being slaughtered, and after the slaughter, the cut meat needs to be attached with a QR code label, and all the meat must be accompanied by a QR code label to be able to achieve Traceability, the work is very cumbersome and troublesome, and in the traceability, only consumers can inquire, the lack of necessary supervision departments makes it difficult to protect rights, and a complete food traceability system cannot be formed without a strong supervision, so people need a A platform that can connect farmers, distributors, retailers, consumers, and regulators to effectively create a trusted brand to meet people's needs
