Abstract
A simple and rapid analytical procedure for determination of saccharin SAC and acesulfameK ACK based on UVvis measurements and partial least squares PLS was proposed Thus an experimental design at levels 2 and 15 mg l−1 for SAC and 2 and 20 mg l−1 for ACK was applied Because real samples usually contain SAC and ACK combined with aspartame ASP this interference was also included in the model The procedure was successfully applied for SAC and ACK simultaneous determination in sweeteners and fruit juice powders without any separation step to remove ASP The results were validated by using spiked samples and the obtained recoveries were satisfactoryThe authors acknowledge financial support from Universidad Nacional and Proyecto Grupo de Investigación PGI granted for Secretaría General de Ciencia y Tecnología Argentina BS Fernández and NE Llamas wishes to thank Consejo Nacional de Investigaciones Científicas y Técnicas CONICET Argentina
