General Information
The food additive E101(ii) is a subtype of the food additive E101 and is known as riboflavin-5′-phosphate sodium. It is a phosphorylated form of riboflavin, characterized by increased water solubility.
The chemical formula of the compound is C₁₇H₁₉N₄NaO₉P, reflecting the presence of a phosphate group and a sodium ion.
Riboflavin-5′-phosphate sodium is obtained through chemical or enzymatic modification of riboflavin, followed by neutralization of phosphoric acid with sodium salts. This approach makes it possible to obtain a stable compound with predictable technological properties.
The main feature of the E101(ii) form is its good solubility in water, which significantly expands the possibilities for its use in liquid and semi-liquid products. The E101(ii) additive has a yellow color, is stable over a wide pH range, but, like other riboflavin derivatives, remains sensitive to intense light.
In the food industry, the food additive E101(ii) is used primarily in beverages, infant and dietary foods, as well as in foods for medical purposes, where uniform distribution of the colorant and the vitamin is important. It combines the functions of a colorant and a source of vitamin B₂.
