Abstract

Abstract: Analyze the whole process of determination of acesulfame in cakes by UPLC-MS/MS method,confirm the source and size of uncertainty,synthesize the uncertainty,calculate the expanded uncertainty and report the results.The content of acesulfame was 0.940 9 mg/kg,and its expanded uncertainty was 0.39 mg/kg.Through the analysis of the source of uncertainty and the quantitative evaluation of each component,the preparation process of the standard working solution is the main source of uncertainty.

Key words: UPLC-MS/MS, acesulfame, uncertainty
