中文摘要:

      食品安全检验中的计量溯源性是保证检验结果准确可比、验证有效的基础, 一般可以按照实际操作实现定义的测量单位、包含非序数量的测量单位的测量程序、测量标准3种参考对照途径进行, 在实际食品安全检验过程中, 由于参考物质的缺失或者结果并不与国际单位相关等原因, 需要综合考虑参考对照体系的构建过程, 通过对固定化检测程序的评价, 形成相应的测量程序, 并通过定量转化关系确定溯源的目标,在形成检验共识性目标的基础上, 通过替代的关系, 建立较为完整的溯源链条, 用于实际检验的溯源。本研究分析了食品安全检测过程中的计量溯源问题, 提出了几种不同的替代实验方案, 为食品安全检验的计量溯源性问题提供了满足检测要求的解决方案。

英文摘要:

      The metrological traceability in food safety inspection is the basis for ensuring the accuracy comparability and validity of inspection results. Generally, it could be carried out in accordance with 3 kinds of reference control pathway, including the actual operation realizes the defined measurement unit, measurement procedures including measurement units of non-ordered quantities, and measurement standard. In the actual food safety inspection process, due to the lack of reference materials or the results are not related to international units and other reasons, it is necessary to comprehensively consider the construction process of reference control system. Through the evaluation of the immobilized testing procedures, the corresponding measurement procedures are formed, and the traceability targets are determined through quantitative transformation relationships. A relatively complete traceability chain can be established on the basis of the formation of a consensus goal of inspection and through the substitution relationship, which can be used for the traceability of the actual inspection. This paper analyzed the problem of metrological traceability in the food safety inspection process, and proposed several different alternative experimental schemes, so as to provide solutions to meet the testing requirements for the problem of metrological traceability in food safety inspection.
