Totally Automated Method for the Determination of Sudan Dyes in Food via On-Line Filtration, SPE and HPLC Analysis

Sudan dyes are categorized as Class 3 carcinogens by the International Agency for Research on Cancer (IARC), and therefore, are illegal as food additives according to both FDA and the EU. Since 2003, European nations have required random product testing and testing of suspected adulterated products. Items found to contain Sudan dyes must be disposed of as hazardous waste. The application note describes a totally automated approach to the extraction of Sudan dyes from food products.
