Brilliant Blue FCF (Blue 1), also known under commercial names, is a colorant for foods and other substances to induce a color change. It is denoted by E number E133 and has a color index of 42090. It has the appearance of a reddish-blue powder. It is soluble in water, and the solution has a maximum absorption at about 628 nanometer.
Chemistry
It is a synthetic dye produced using aromatic hydrocarbons from petroleum.[1] It can be combined with tartrazine (E102) to produce various shades of green.
It is usually a disodium salt. The diammonium salt has CAS number [2650-18-2]. Calcium and potassium salts are also permitted. It can also appear as an aluminium lake. The chemical formation is C37H34N2Na2O9S3. The dye is poorly absorbed from the gastro-intestinal tract and 95% of the ingested dye can be found in the feces. It also reacts with certain bile pigments to form green feces.[citation needed]
