In order to realize the tropical fruit quality safety traceability, the paper proposes that using two-dimensional bar code (QR Code) technology constructs the tropical fruit quality safety traceability system. On the basis of the study of the two-dimensional bar code (QR Code) technology in Manufacturing Environment, author analyzes the elements involved of tropical fruit production and circulation, uses HACCP, FMECA and other technical methods, puts forward the key elements of the quality and safety of tropical fruit, uses country and industry relevant coding standard, and constructs tropical fruit quality safety traceability system based on two dimensional bar code (QR Code). Application shows that the tropical fruit companies or production bases by using the system improve the tropical fruit production safety management level, realize the tropical fruit quality safety traceability, promote tropical fruit industrialization and standardization management.
