科协双语工程论文展播：区块链技术在食品溯源体系中的应用

Abstract: Blockchain technology is a ledger technology that can be widely used in various industries on the basis of computer technology in recent years.Due to its high efficiency, continuity and non-modifiable characteristics, blockchain has been highly praised by relevant people. Frequent food safety accidents pose a major threat to the life and health of consumers, and also make the public put forward high requirements for the whole-process holographic control concept and technology of food safety. It is urgent to establish a new food safety risk information traceability control system to ensure the efficient and smooth transmission of information in the food supply chain, and to promote the disclosure of production information and reduce the trust problems caused by the centralization of information.This paper mainly explores the method of constructing the traceability system of grain and its products, food and medicine dual-use food, fresh and cold food using Blockchain. In the analysis of food adulteration incidents, blockchain technology can ensure the reliability of information sources in the supply process and the reciprocity of information reliability and ownership.Combined with the Internet of Things technology, the producer, government, consumers and other parties to supervise and inspect to curb the adulteration of food. Finally, the role of blockchain technology in food information safety supervision is discussed, and a unified coding system and dense available technology are proposed to realize the inspection of food safety information by food regulatory authorities and consumers. Blockchain is a technology integration of multiple disciplines and fields such as computer. It is necessary to effectively combine blockchain with food supply chain and supervision to realize the role of blockchain in food safety and food traceability system.
