Research on Reference Material of Refined Grade White Granulated Sugar and Uncertainty Evaluation
A reference material of refined grade white granulated sugar has been researched,with its homogeneity and stability thoroughly investigated.Through cooperative certification involving multiple laboratories,its property values were confirmed,and uncertainties were evaluated.The results showed that the homogeneity and stability of this reference material were excellent,with an expiration date exceeding 20 months.The colour property value was(11.3±1.4)IU,conductivity ash property value was(0.00482±0.00020)%,sucrose content property value was(99.82±0.06)%,and reducing sugar content property value was(0.0114±0.0018)%.This reference material of refined grade white granulated sugar fills a crucial gap in both domestic and international development.It conformes to the requirements of the directives for the work of reference materials and it would be used for quality control and capability validation in the laboratory.
