New enzyme granules are provided with improved properties. The granules are based on core particles having a good pore size and pore size distribution to allow an enzyme solution to enter into the particle. Accordingly, the core material comprises the enzyme in liquid form, thus eliminating the drawback of processing powdered enzymes. Still, good flowability and metering properties are obtained. The enzyme-containing granules are preferably coated with a film-forming macromolecular material. These granules have lower dustiness and improved mechanical strength. Also a method of preparing these enzyme granules is provided.
