Abstract: Lyophyllum decastes is a rare edible fungus and its quality has attracted much attention from consumers. The large-scale cultivation of Lyophyllum decastes factories has entered a period of rapid development, and in order to improve the brand of the enterprise, the requirements for quality control are also very strict. Based on these requirements, the basic traceability unit for quality safety of Lyophyllum decastes, the critical control point and the quality test indexes were analyzed. The weight of each evaluation factor was determined by using the evaluation index system of two-level traceability precision and the analytic hierarchy process (AHP) which included constructing judgement matrix, hierarchical single sort and consistency test. Then the quality traceability information index model of Lyophyllum decastes was established based on expert opinions and Delphi method, which provided a design basis for the development of the quality and safety traceability system of Lyophyllum decastes based on block chain. A new on-chain and off-chain data synchronization strategy is designed to reduce the possibility of data tampering. The smart traceability system for the entire process of Lyophyllum decastes factory production has been developed by using both MVP architecture and microservices architecture separately for mobile terminal and desktop platforms, thereby promoting the quality control in the process of production and ensuring the food safety.
