CE separation of the polyols was achieved in less than 6 min, and it was mediated by the interaction between the polyols and the borate ions in the background electrolyte, forming negatively charged borate esters. The extraction of the polyols from the samples was simply obtained using ultra-pure water and ultrasonic energy. Linearity was assessed by calibration curves that showed R-2 varying from 0.9920 to 0.9976. The LOQs were 12.4, 15.9, 9.0, and 9.0 mu g/g for erythritol, maltitol, xylitol, and sorbitol, respectively. The accuracy of the method was evaluated by recovery tests, and the obtained recoveries varied from 70 to 116% with standard deviations ranging from 0.2 to 19%. The CE-(CD)-D-4 method was successfully applied for the determination of the studied polyols in commercial samples of sugar-free chocolate.372229862991Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAFESP) [2013/22485-6, 2013/22127-2]Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq) [305318/2012-8]Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)
