Problems solved by technology

With the continuous refinement and diversification of the food industry chain, the efficiency of the conventional quality management traceability system has declined and the cost has increased. At the same time, due to the lack of a quality and safety traceability system for hazard factors, it is difficult to quickly and accurately find the source of hazards
In addition, the food safety traceability system of traditional technology still has the following problems: 1) A small number of central database institutions hold most of the valuable information, which is easy to form a high-cost and low-efficie

Embodiment 1

[0042] Take the application of the food quality and safety management system and method based on blockchain technology in rice food as an example.

[0043] Food quality and safety management system based on block chain technology, please refer to figure 1 , including storage layer, service layer, interface layer, function layer, management layer and user layer;

[0044] The storage layer is based on the alliance blockchain technology architecture and is presented in the form of a node cluster, which is used to store the data entering the system in a distributed manner in the database;

[0045] The service layer includes the account system management module, distributed ledger, algorithm support module and service management module; among them, the account system management module is used to realize the service functions related to the account and provide functional support for user registration and authority management; the distributed ledger is used for Consensus algorithms,...

Embodiment 2

[0053] Take the application of the food quality and safety management method based on blockchain technology in rice food as an example.

[0054] Food quality and safety management methods based on blockchain technology, including food quality intelligent management and food quality and safety control;

[0055] see Figure 4 , food quality intelligent management includes the following steps:

[0056] 1) Intelligent control of production: the algorithm support module establishes an algorithm support library based on the relationship between production process parameters and food quality, food laws and regulations, and food quality standards; the block chain module establishes participants as upstream and downstream of the production line based on food quality standards and laws and regulations The production intelligent control smart contract of the process (such as image 3 The production process shown is about the smart contract of heavy metal cadmium and mercury); the data ...

Abstract

The invention discloses a block chain technology-based food quality safety management system and a food quality safety management method. The system comprises a storage layer, a service layer, an interface layer, a function layer, a management layer and a user layer. The method comprises the steps of food quality intelligent management and food quality safety control. According to the invention, the block chain technology has the advantages of de-centralization, information transparency, non manipulation and the like. In combination with the internet of things sensor technology, the automaticdata acquisition is realized. Through the big data technology, the data information can be mined and analyzed. Therefore, a distributed, efficient and reliable food safety source tracing system is established. In addition, an intelligent contract is established, so that the automatic processing of the information is realized. A trust relationship between nodes is established according to a mathematical method. As a result, the third-party guarantee is not needed, and the transaction can be directly carried out between enterprises. The enterprise efficiency is greatly improved, and the cost isreduced.

Description

technical field [0001] The invention belongs to the field of food quality and safety management, and the specific technology relates to a food quality and safety management system and method based on block chain technology. Background technique [0002] At present, my country realizes the supervision and control of food quality and safety by establishing relevant food quality and safety management institutions, guiding enterprises to establish modern quality control systems, traceability systems and other information-based means. However, because high-value information is controlled by a small number of institutions, information asymmetry caused by selective disclosure, shielding or tampering of information, and the lack of an efficient food quality and safety control system. In the past ten years, exposures have been made of melamine, aflatoxin, Sudan red, clenbuterol, heavy metals, pesticides, illegal chemicals and other harmful factors in milk powder, rice, meat products,...
