Objective To realize the quality safety traceability of the production and circulation of tropical fruit, standardize enterprise production management, improve the consumers' right to know, and strengthen government supervision. Methods On the basis of the study of the two-dimensional code technology, the elements involved in tropical fruit production and circulation were analyzed using HACCP, FMECA and other technical methods, and the key elements of the quality and safety of tropical fruit were put forward. Using country and industry relevant coding standards, the code structure of tropical fruit quality safety traceability was designed,and the tropical fruit quality safety traceability system was constructed based on two-dimensional code technology. Conclusion By using this system, the tropical fruit production safety management level of the tropical fruit companies or production bases was improved, the tropical fruit quality safety traceability was realized, and tropical fruit industrialization and standardization management were promoted.
