- Abstract
In order to ensure the reliability of testing, measurement uncertainty arising from analysis can be useful scientific evidence. In this study, we analyzed food preservatives (sorbic acid [SOA], benzoic acid [BA], and dehydroacetic acid [DHA]) and sweetener additives (acesulfame potassium [Aces-K], and sodium saccharin [Sac-Na]) in many kinds of processed food by a simultaneous determination method with carrez extraction, and estimated measurement uncertainty with a top-down approach. The recoveries from 23 kinds of food fortified with sweetener additives at a level of 0.10 g/kg, and with food preservatives at 0.15 g/kg, were 82~98%. Repeatability was 0.9~3.1%, and the within-laboratory reproducibility was 4.2~6.8%. Considering expanded measurement uncertainty, the range of analytical values obtained in our laboratory will be limited as follows: Aces-K, 0.090~0.11 g/kg; Sac-Na, 0.082~0.11 g/kg; SOA, 0.12~0.16 g/kg; BA, 0.13~0.16 g/kg; and DHA, 0.11~0.14 g/kg.
