A high performance liquid chromatographic method with evaporative light scattering detection (HPLC-ELSD) was developed for the determination of sucralose in dairy foods. Sucralose was extracted by precipitating samples with 0.2% acetic acid solution, cleaned up on a C18 solid phase extraction cartridge and concentrated prior to HPLC-ELSD analysis. The relationship between logarithmic peak area and logarithmic sucralose concentration was linear over the range of 0.1 to 0.8 g/L, with a correlation coefficient (R2) of 0.9991. The recoveries of sucralose from spiked milk powder and liquid milk ranged between 94% and 102%. The limit of detection was 2 mg/L (RSN = 3).
