Abstract

Riboflavin produced by a microbial method is prepared in the form of free-flowing, non-dusting, spray-dried granules or microgranules as a feed additive by removing water from the mixture discharged from microbial fermentation for the preparation of riboflavin, wherein the mixture is subjected to PA1 (a) a fluidized-bed spray-drying process PA1 (b) a one-material spray-drying process or PA1 (c) a disk spray-drying process without significant amounts of binders being added to the discharged fermentation mixture.
