Capillary electrophoretic methods have been developed for the analysis of Monascus yellow pigments for food additives. Monascus yellow pigments were successfully separated by micellar electrokinetic chromatography (MEKC) with a 20mM sodium dodecyl sulfate (SDS) solution containing 50mM phosphate buffer, pH 7.0, and 20% acetonitorile or a 2.0% butyl acrylate/butyl methacrylate/methacrylic acid copolymer sodium salts (BBMA) solution containing 20mM ammonium formate buffer, pH 7.0, and 10% methanol. The xanthomonasin A was identified with the molecular mass measured by FABMS. Monascus yellow pigments were extracted from candies with solid phase extraction and analyzed by the developed technique.
