The aim of this study was to develop a quadrupole liquid chromatography mass spectrometry (LC-MS/MS) method suitable for quantification of synthetic food colors, used as additives or occurring as adulterants in the food or cosmetics industries. Ten colors were validated in terms of limit of detection (LOD), limit of quantification (LOQ), precision, trueness and applicability. All tested parameters of the validation were within acceptable values, and the method was comparable to the existing high pressure liquid chromatography (HPLC UV-PDA) method.
