Abstract: Process for producing microbially prepared riboflavin in the form of spray or microgranules which are free-flowing and non-dusting as feed additive by removing water from the discharge from microbial fermentations for preparing riboflavin, characterised in that the fermentation discharge is subjected to a) a spray fluidised bed drying b) a single-component nozzle atomiser drying or c) a disc atomiser drying without adding substantial amounts of binders to the fermentation discharge.
