| Food safety issues are a major issue related to people's livelihood.In recent years,China's food safety incidents have emerged in an endless stream.The events of Sudanese red duck eggs,melamine milk powder,waste oil,and lean meat essence are shocking.It is extremely urgent to solve the problems in the food safety field.Food safety traceability is an important means to control food safety.The current food safety traceability methods include paper account traceability,electronic information coding technology,biotechnology,and ultra-micro analysis technology.However,these food traceability technologies lack unified management.Each enterprise method does not form a unified code and logo,cannot exchange data and information cannot be shared.The blockchain technology has the advantages of openness,transparency,traceability and traceability,also can solve the problems of the current food traceability method.This paper first studies and analyzes the key technologies of blockchain,and expounds the importance and feasibility of the combination of blockchain technology and food safety traceability.Then,according to the shortcomings of the centralized traceability system,the block-based technology platform super-books Fabric was used as the technology platform.The infant formula with frequent problems in food safety was selected as the research object of this method,and the blockchain was designed.Food traceability program.The architecture and specific process of the solution and the detailed functions of each module are designed.Finally,the program was implemented in detail,and the environment of the super-books fabric was built.The development and design of the chain code was carried out,and the main functions of the page were demonstrated.The traceability program records the quality and safety information of each step of the milk powder from production to sales,and realizes the quality and safety traceability of the milk powder products from production to sales. |
