Polysaccharides produced by fermentation are obtained in a non-fibrous form by washing the product produced by precipitation from the fermentation medium with an aqueous organic liquid in which the proportion of organic liquid is high enough to give a washed product which is not soft, difficult to dry and with a tendency to agglomerate, but not so high that the washed product, after drying and grinding, has a fibrous structure, and then drying and grinding the washed polysaccharide.
