ERYTHROSIN B Usage And Synthesis

Description

FD & C Red No. 3 is principally the disodium salt of the monohydrate of 9(ocarboxyphenyl)-6-hydroxy-2,4,5,7-tetraiodo-3H- xanthen-3-one.
The colorant is a brown powder that dissolves in water to give a solution red at neutrality, with a yellow-brown precipitate in acid, and with a red precipitate in base. When dissolved in concentrated sulfuric acid, it yields a brown-yellow solution that evolves iodine and a precipitate of the free acid when heated.
FD & C Red No. 3 is used in dietary supplements, confectionery products, dairy products, cherries, jellies, jams, dessert powders, canned fruit and vegetable products, fish products, condiment sauces and bakery goods.1 .

Chemical Properties

red to brown powder

Uses

antibacterial

Uses

Erythrosine B is a derivative of fluorone and is used as a cherry-pink synthetic colour additives used on food products.

Uses

Biological stain; color additive.

Uses

Erythrosin B (FD&C Red #3) is a colorant. It is not recommended for use below ph 5.0, being insoluble at ph 3–5 but being stable at ph 7 and 8. It has a solubility in water of 9 g/100 ml at 25°c. It has fair stability to oxidation and poor to fair stability to light, while having good stability in 10% sugar systems. It has exceptional clarity and brilliance, having a bluish pink hue with very good tinctorial strength. It has poor compatibility with food components and is used in candies and confections as well as cherry dyeing. The common name is erythrosine.

Definition

ChEBI: An organic sodium salt that is the disodium salt of 2-(2,4,5,7-tetraiodo-6-oxido-3-oxo-8a,10a-dihydroxanthen-9-yl)benzoic acid.
