Caramel liquid, obtained by heat treatment of sugars, is commonly used to alter the taste or colour of food products.Among promoters of caramelization allowed, ammonia (for caramel colours of class III) and ammonium salts (for those of class IV) are a source of neoformed contaminants (NFC) such as 2-acetyl-4-(1,2,3,4-tetrahydroxybutyl)imidazole (THI), immunosuppressive agent, and 4-methylimidazole (4MeI), convulsive agent. These molecules have contents limited by the European regulations to 10 and 250 ppm, respectively.To improve knowledge of the chemistry of caramel and quality of caramel colours by controlling the formation of NFC, it is necessary to develop analytical methods that are both reliable, fast and easy to implement.
