Sudan Dyes

Sidebar Image

Sudan dyes, e.g. Sudan I to IV, Sudan Orange G, Sudan Red B, Sudan Red G, and Sudan Red 7B as well as other dyes like 4-(dimethyl-amino) azobenzene (Butter Yellow) and Para Red are basically synthetically produced red azo dyes. Their degradation products are considered to be carcinogens and teratogens. Due to this fact, the EU does not permit the use of these colours as food additives. However, in some countries, these dyes are still occasionally used in order to intensify the colour of bell pepper and chilli powder.
