A sensitive and fast method for the quantification of the illegal dye chrysoidine in aquaculture products with ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) is presented. Muscle tissues were made alkaline with sodium hydroxide and extracted with ethyl acetate. After evaporation and subsequent defatting with n-hexane, extracts were directly injected onto the UPLC-column. Chromatography was performed on a C(18) column using 0.1% formic acid in water and an acetonitrile gradient within 6 min. Mass spectrometric analysis was performed in the positive electrospray…
