Food safety traceability method and device

Abstract

The invention provides a food safety traceability method and device. The method includes: obtaining ingredient identification information in the process of food production, processing and transportation. The ingredient identification information includes but not limited to production date, shelf life, storage conditions, and quality information; comparing the ingredient identification information The degree of matching with the corresponding pre-stored food safety standard data is used to detect whether the food is qualified; when the food is detected to be unqualified, the ingredient identification information in the process of food production, processing and transportation is retrieved to determine the corresponding error link; when the food is detected to be qualified, According to the matching degree, the corresponding quality and safety assessment information is generated and stored in the blockchain. Through the technical solution of the present invention, the quality and safety of food and anti-counterfeit traceability are effectively guaranteed, which is beneficial to safeguarding the interests of consumers, and at the same time, it is also conducive to standardizing the industry system and improving the supervision effect. Any problem in food safety in any link can be resolved in the district. It is certified on the block chain, which clarifies the subject of responsibility and improves the efficiency of supervision.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a food safety traceability method and a food safety traceability device. Background technique [0002] Blockchain is a new type of decentralized protocol that can safely store digital currency transactions or other data, information cannot be forged and tampered, and smart contracts can be automatically executed. The emergence of blockchain technology may greatly enhance the informatization level of the food industry, improve the transparency of food safety information, reduce governance costs, and become a powerful tool for the social co-governance system of food safety. Therefore, it also has a role in traceability of baby food safety. very important meaning. At present, the blockchain-based food safety traceability method is mainly to issue digital currency that matches the commodity, and transfer the commodity with the payment of the digital currency. Every ti...
