| Toxicity | A food color formerly approved for use in the United States and Europe. It was used primarily in jams and marmalades, maraschino cherries, pickles and relishes, etc. The LD50 in rats is 150 mg/kg, i.p., and 600 mg/kg, p.o. Erythrosine has a variety of actions in vitro due in large measure to its ability to affect biological membranes and lipophilic sites of enzymes. Such data have led to the hypothesis that erythrosine could be neurotoxic, but both clinical and preclinical data have suggested that erythrosine is not likely to be neurotoxic at doses that might be encountered. Two other toxicological issues have been raised with this food color. It has been suggested to be a potential, if weak, carcinogen, and it may also contribute to potential thyroid toxicity resulting from release of iodine. | |||||||||

ERYTHROSIN B Chemical Properties,Uses,Production
Chemical Properties
orange-red fine powder
Uses
Erythrosin B has been used as a dye in fluorescence lifetime imaging.
Uses
Indicator in analytical chemistry.
Uses
Erythrosin B is used as a red coloring in some foods such as cherries and fish. It is used as printing ink, dental plaque disclosing agent and biological stain. It finds application as a radiopaque medium and sensitizer for orthochromatic photographic films. It is utilized as a cake-decorating gel. In addition to this, it is used in sweets such as candies and popsicles.
Preparation
Fluorescein (C.I.Acid Yellow 73, C.L 45350) in aqueous solution or Tetraiodide in ethanol, and made ??the free acid form.
Biochem/physiol Actions
Erythrosin B, also called as eosin B, is a xanthene dye. It belongs to the family of fluorescein dyes. It plays a major role in inhibiting dopamine uptake and high affinity 3H-ouabain binding and ion transport in synaptosomes from rat caudate nucleus.
Properties and Applications
blue light red. Soluble in water for cherry red, no fluorescence. In concentrated sulfuric acid for brown light yellow, dilution after brown light yellow precipitation. Dye aqueous solution to join sodium hydroxide have soluble precipitation. Used in cosmetics coloring.
