Abstract:

The construction of food traceability system should firstly figure out what information needs to be traced, and in what way the information is organized and managed. The existing food safety traceability system is constructed in view of information system theory. Through integrated management of food quality and safety factors from food production to consumption, the construction of food safety traceability chain has become a new way of traceability system. Based on the theory of food chain, this paper decomposed the process of food chain, proposed the hierarchical model of food safety traceability chain, and analyzed its continuity and integrity. The establishment of food safety traceability chain was not only the foundation for food hazard analysis, quality control, risk analysis, but also a basis for the construction of food safety traceability system.

Key words: food, quality and safety, traceability chain, traceability system

摘要：

食品安全可追溯系统的构建需确定被追溯的信息及信息的组织管理方式。现有食品安全可追溯系统均基于信息系统理论进行构建。通过统筹管理自食品生产至消费全过程所涉及的质量安全要素，基于食品安全追溯链构建的食品安全可追溯系统更快捷有效。基于食品链理论，分解食品链过程,提出了食品安全追溯链的层次模型，进而全面分析了食品安全追溯链的连续性和完整性。食品安全追溯链的建立，不仅是食品危害分析、质量控制、风险分析的基础，同时也是食品安全可追溯系统构建的依据。
