A method using capillary electrophoresis with capacitively coupled contactless conductivity detection was proposed for determination of preservatives in bread. Sample preparation required only an ultrasonic-assisted aqueous extraction of the analytes. The proposed method demonstrated to be simple, fast, and reliable for quantification of propionate and sorbate in commercial samples of bread.
