Characterisation of the active substance as the sodium salt:Erythrosine consists essentially of disodium 2-(2,4,5,7-tetraiodo-3- oxido-6-oxoxanthen-9-yl) benzoate monohydrate and subsidiary colouring matters together with water, sodium chloride and/or sodium sulphate as the principal uncoloured components.The calcium and the potassium salts are also permitted.Chemical formula: C20H6I4Na2O5·H2OCAS number: 16423-68-0Solid form produced by chemical synthesis.Purity criteria- Total colouring matters, calculated as the anhydrous sodium salt ≥ 87 % (assay)
- Inorganic iodides ≤ 0,1 % (calculated as sodium iodide)
- Water insoluble matter ≤ 0,2 %
- Subsidiary colouring matters (except fluorescein) ≤ 4,0 %
- Fluorescein ≤ 20 mg/kg
- Organic compounds other than colouring matters:
- Tri-iodoresorcinol ≤ 0,2 %
- 2-(2,4-dihydroxy-3,5-diiodobenzoyl) benzoic acid ≤ 0,2 %
- Ether extractable matter from a solution of pH from 7 through 8 ≤ 0,2 %

Analytical methodFor the quantification of erythrosine in the feed additive:- spectrophotometry at 526 nm (Commission Regulation (EU) No 231/2012 refers to FAO JECFA monographs n. 1 (Vol. 4))
For the quantification of erythrosine in feedingstuffs:- high performance liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS)
