Analysis of Illegal Dyes in Food Matrices Using Automated Online Sample Preparation with Liquid Chromatography-Mass Spectrometry

Instrument Type: LCMSMS

Sudan dyes are red dyes used for coloring solvents, oils, waxes, petrol, or as additives in shoe and floor polish. They have been found in a number of food products such as chili / chili-containing products. Sudan dyes are banned as food additives in the USA, the EU, and many other countries, due to their links to cancer and other negative health effects. To overcome limitations in popular offline SPE and LC-UV measurements, we describe an easy, comprehensive LC method using a Transcend TLX-1 system powered by TurboFlow technology to analyze five illegal dye residues in a variety of sauces.
