摘　　要：三氯蔗糖，又名蔗糖素，属于紫外末端吸收化合物，极易溶于水，甜度为蔗糖的600倍，且甜味纯正，甜味特性曲线几乎与蔗糖重叠。它是以蔗糖等为原料经脱氧、氯化衍生而得到的半天然半合成产品，属非营养型强力甜味剂，在人体内几乎不被吸收，热量值为零。A method was developed for the determination of sucralose in soft drink by liquid chromatography （LC） tandem a charged aerosol detector（CAD） with post column compensation. The results showed that the linearity was good and the correlation coefficient was above 0. 999. The limit of quantitation of the method was 1.0 mg/L, and the recoveries of spiked samples were 97.6% -112%. The method was simple and accurate, and can be used for the determination of sucralose in soft drink.
