Abstract: The present invention relates to an improved process for preparing riboflavin of the B/C modification in granule form. Furthermore, the invention relates to the riboflavin preparation process wherein riboflavin of the A modification is (a) dissolved in aqueous mineral acid without treating the resulting riboflavin solution with activated carbon, (b) precipitated directly afterwards, steps (a) and (b) being carried out at a temperature in the range from 5 to 15° C., and (c) dried by fluidized bed granulation; and wherein the riboflavin does not come into contact with the aqueous mineral acid solvent for longer than on average 4 hours.

Abstract: Riboflavin is removed from fermentation suspensions by them being heated at from 50 to 90.degree.C for from 1 to 3 hours, then cooled to from 0 to 30.degree.C over a period of from 1 to 5 hours, and subsequently being centrifuged to give a sediment fraction and liquid fraction in such a way that the sediment fraction contains predominantly riboflavin crystals as solid, and the liquid fraction contains virtually no crystalline riboflavin, and, where appropriate, resuspending the sediment fraction in from 0.5 to 2 parts by volume of water per part by volume of sediment fraction and repeating procedure c.
