Other names for the additive (synonyms)
General Information
The food additive E101(i) is a subtype of the food additive E101 and is known as riboflavin. It is a water-soluble B-group vitamin that functions as a biologically active colorant and a nutrient.
The chemical formula of riboflavin is C₁₇H₂₀N₄O₆. By its chemical nature, it belongs to isoalloxazine derivatives and is characterized by a bright yellow or yellow-orange color.
Riboflavin is obtained mainly by biotechnological methods—through microbiological fermentation using specially selected strains of bacteria or fungi. In the past, chemical synthesis was also used, but it has largely been replaced by biotechnological approaches due to their higher economic efficiency and environmental friendliness.
Riboflavin is resistant to oxygen and high temperatures; however, it is sensitive to light, especially ultraviolet light, under the influence of which it gradually degrades. It is poorly soluble in water but sufficiently stable in dry form, which makes it convenient for use in food products.
In the food industry, the food additive E101(i) is used as a natural colorant to impart a yellow color to beverages, dairy products, desserts, confectionery, and breakfast cereals. In addition, riboflavin is used to fortify foods with vitamin B₂.
