农产品及食品质量安全追溯系统关键技术研究进展

Key Technologies for Establishment Agricultural Products and Food Quality Safety Traceability Systems

追溯系统作为控制农产品及食品质量安全的有效方法在国内外日益受到重视。首先辨析了可追溯性和追溯系统概念;在此基础上从追溯编码与产品标识技术、供应链各环节信息快速采集技术、质量安全智能决策与预警技术和溯源数据交换与查询技术四方面综述了国内外研究进展;结合物联网的技术特点构建了'一核、双轴、三链'的农产品及食品质量安全追溯系统技术体系框架;最后分析了实施追溯系统急需解决的问题。

Traceability systems gain more attention in worldwide as an effective method for controlling agricultural products and food quality safety. The concepts of traceable and traceability system were discriminated. Key technologies for establishment traceability systems, such as coding and identification, real-time record keeping in the supply chain, intelligent decision making and early warning and data exchange and query, were summarized. Combined IOT（internet of things） technology, the technology framework of traceability system including one kernel, two axes and three chains was constructed. One kernel means to implement the goal of agricultural products and food quality safety traceability. Two axes are the supply chain from farm to table as the horizontal axe and the IOT technologies from information sensing, information transmission to intelligent decision as the vertical axe. Three chains include products chain for supply lifecycle, service chain for supply chain actors and technology chain for IOT. Furthermore, the urgent problems for implement the traceability system were put forward, which included unified encoding, low cost and quick information collection equipment, application system with intelligent decision model and collaborative traceability platform.
