Sudan I (also commonly known as CI Solvent Yellow 14 and Solvent Orange R), is an organic compound, typically
classified as an azo dye. It is an intensely orange-red solid that is added to to colourise waxes, oils, petrol,solvents and
polishes. Sudan I has also been adopted for colouring various foodstuffs, especially curry powder and chili powder,
although the use of Sudan I in foods is now banned in many countries, because Sudan I, Sudan III, and Sudan IVhave
been classified as category 3 carcinogens (not classifiable as to its carcinogenicity to humans) by theInternational Agency
for Research on Cancer. Sudan I is still used in some orange-coloured smoke formulations and as a colouring for cotton
refuse used in chemistry experiments.
Toxicology
Sudan I is genotoxic. It is also carcinogenic in rats. Comparisons between experimental animals and human Cytochrome
P450 (CYP) strongly suggest animal carcinogenicity data can be extrapolated to humans.
Sudan I is also present as an impurity in Sunset Yellow, which is its disulfonated water-soluble version.
Food scare
In February 2005, Sudan I gained attention, particularly in the United Kingdom. A Worcestershire sauce produced by
Premier Foods was found to be contaminated with Sudan I. The origin was traced to adulterated chili powder.
