Recent progress on detection of synthetic dyes in food by liquid chromatography-tandem mass spectrometry

Synthetic dyes are widely used to give and improve food color due to its low price, strong coloring ability and stable properties. However, the abuse of synthetic dyes such as over-range use, over-limit use, and illegal use will adversely affect the health of consumers. Therefore, high-sensitivity and high-accuracy analytical methods are required to detect synthetic dyes in food to ensure food safety. Liquid chromatography-tandem mass spectrometry has the advantages of high selectivity, high sensitivity, and accuracy, and it plays an important role in the screening and quantitative analysis of synthetic dyes. This article reviews the research progress of liquid chromatography-tandem mass spectrometry in the detection of synthetic dyes in food, including the pretreatment, separation, and mass spectrometry of synthetic dyes. The future development trend of liquid chromatography-tandem mass spectrometry in the field of synthetic dye detection was forecasted, aiming to provide reference and ideas for the further development of detection methods for synthetic dye.
