Azorubine is a monoazo dye that occurs as red powder or granules. It is principally the disodium salt of 4-hydroxy-3-(4-sulfonato-1-naphthylazo)- 1-naphthalenesulfonate and subsidiary coloring matters together with sodium chloride and/or sodium sulfate as the principal uncolored components. It may be converted to the corresponding aluminum lake.
Typical applications include beverages, confectionery, bakery, dairy fats and oil, meat, seafood, snacks, dry mixes and seasonings, fruit preparation, convenient food, and pharmaceuticals.
Azorubine (INS No. 122) is added to foods and beverages at concentrations up to a maximum permitted level (MPL) as established by the Codex Alimentarius Commission. There are currently 7 food categories for which MPLs for azorubine have been adopted in the General Standard of Food Additives. Many other applications of azorubine (carmoisine) as a color additive in foods and beverages have been proposed and are pending adoption, following completion of the review and comments process.
