Coloring Agent
1. FD&C Blue No. 1 – Brilliant Blue FCF, E133 (blue shade)
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.
-------------------------------------------------
Applications
As a blue color, Brilliant Blue FCF is often found in ice cream, canned processed peas, packet soups, bottled food colorings, icings, ice pops, blue raspberry flavored products, dairy products, sweets[2] and drinks, especially the liqueur blue curacao. It is also used in soaps, shampoos,mouthwash[3] and other hygiene and cosmetics applications. In soil science, Brilliant Blue is applied in tracing studies to visualize infiltration and water distribution in the soil.
-------------------------------------------------
Health and safety
Brilliant Blue FCF has previously been banned in Austria, Belgium, Denmark, France, Germany, Greece, Italy, Spain, Sweden, and Switzerlandamong others[4] but has been certified as a safe food additive in the EU and is today legal in most of the countries. It has the capacity for inducing anallergic reaction in individuals with pre-existing moderate asthma.[5]
