食品安全检验量值溯源体系的构建

测量结果的计量溯源性对于保障食品安全检验结果的有效性至关重要。作者从食品安全检验量值溯源体系的建立入手,按不同溯源的因素对检验结果有效性的贡献进行评估,建立适当的控制级别,提出了食品理化、微生物和分子生物学领域的量值溯源体系模型,根据该体系模型,对食品安全检验实验室常见检验参数(项目)和方法标准中的重要溯源的因素,如标准物质、重要仪器、溯源等级图等进行评估、分析和研究,形成了量值溯源数据体系架构,构建了食品安全检验量值溯源软件系统平台,期望为食品安全检验实验室提供一个量值溯源数据共享平台,帮助实验室科学、系统地建立食品安全检验量值溯源体系。

Construction of Traceability System for Food Safety Inspection

Metrological traceability is very important for ensuring data validity of food safety inspection. The validity of inspection results was evaluated according to the contribution of different traceability factors based on the establishment of traceability system for food safety inspection. The appropriate control level was established and the quantitative traceability model was proposed in the fields of food physics and chemistry, microbiology and molecular biology. According to the traceability model, the important traceability elements, such as reference material, important equipment, and hierarchy schemes were assessed, analyzed and studied on the common inspection parameters/items and method standards used in the food safety inspection laboratories, forming a metrological traceability data frame and constructing the software system platform of the food safety testing measurement traceability. It''s expected to provide a data-sharing platform for food safety inspection laboratory and establish a scientific and systematic metrological traceability system of food safety inspection.
