Block chain technology-based food quality safety management system and food quality safety management method

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,...

AI Technical Summary

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-efficiency operation status; information providers can selectively block or even tamper with unfavorable information 2) The links in the food industry chain are becoming more and more refined, involving many links, elements and participants, and the communication costs are huge; 3) The quality and safety control of food is generally carried out by monitoring the hazardous components of the finished product. Sampling inspection, there are problems such as long sampling and inspection cycle, untimely discovery of hazards, resulting in unqualified products flowing into the market, and great food safety hazards
