Vitamin B2 > as additive for food production

Physiological importance

Riboflavin acts as a co-enzyme in a large number of oxidizing and reducing enzymes and thus plays a role in the transfer of hydrogen atoms during the energy generating oxidation processes within the cell, known as the respiratory chain. Therefore, riboflavin – along with other B-complex vitamins – acts as a coenzyme in the protein, fat and carbohydrate metabolisms, as well as in the generation of energy via ATP.
Furthermore, riboflavin is involved in the metabolism of other B-vitamins (folic acid, pyridoxine and niacin) and in the production of hormones in the adrenal cortex.

Deficiency symptoms

  • changes inside the mouth (inflammation of the mucous membranes, changes on the lips, tongue and in the gastrointestinal tract)
  • changes of the skin (seborrhoic dermatitis, dystrophia of the finger nails)
  • changes in the eyes (keratitis, opacification of the lens, vascularization of the cornea, cataract)


Vitamin B2


Two Vitamin B2 grades are available in powder form.
Stability: Stored in its unopened original packaging at room temperature (max. 25 °C), protected from light and moisture, the product is stable for at least 36 months. Because the product is hydroscopic, it is recommended to hermetically reseal the remaining product in the packaging. Riboflavin is resistant to heat in acid solutions in the absence of light. It is sensitive to alkaline substances, heavy metal salts, and light. Reducing agents convert it to colourless leuco compounds.


Riboflavin fine powder was developed for the fortification of powder food products and staple food, such as flour. Because of its fine particle size it is particularly suitable for use as colorant in powder food products or powders, which must be dissolved in water or milk prior to consumption.
Riboflavin high flow 100 is the grade which may be applied related to dietary supplements. It can be used in all solid and liquid dosage forms such as tablets, hard-shell capsules, effervescent and other instant formulae. It is ideal for use in multivitamin formulations. Moreover it is recommended for the fortification of various food and beverage products, such as multivitamin juices, baby food, and instant-drink powders.
