Abstract
A method for producing a granulated riboflavin product comprises making a specific mixture of riboflavin, binder and water, followed by homogenizing the mixture and thereafter spray-drying the homogenized mixture so that granules are produced. The mixture has a relatively high vitamin and binder content but is reduced to a relatively low viscosity (via homogenization) so that spray drying can be performed.
