Determination of synthetic dyes in bean and meat products by liquid chromatography with tandem mass spectrometry.

摘要: A sensitive and efficient method was developed for the simultaneous determination of eight synthetic dyes (Chrysoidin, Auramine O, Sudan(I-IV), Para Red, Rhodamine B) in bean meat products using high-performance liquid chromatography with tandem mass spectrometry. simple extraction procedure acetonitrile has been applied these from spiked samples. Chromatographic separation achieved on a Waters XTerra C18 column (2.1 × 150 mm, 5 μm) multistep gradient elution. Detection quantification were performed spectrometry multiple reaction monitoring mode. Linear calibrations obtained correlation coefficients R(2) > 0.99. The limits detection ranges 0.03-0.75 0.1-2.0 μg/kg depending matrices, respectively. recoveries different food matrices between 71.2 116.9% relative standard deviations <15.2%, suggesting that is promising accurate at trace levels products.
