A product obtained by granulating an enzyme powder must avoid emitting dust, possess high strength, exhibit the property of quickly dissolving in water where such ready solution is necessary for the intended application, defy absorption of moisture or deformation for a long time, and preserve without a sacrifice of activity. The method of this invention produces granules of raw enzyme powder possessed of the qualities mentioned above by admixing the enzyme powder with polyethylene glycol or polyoxyethylene-polyoxypropylene block polymer of specific quality as a binder and granulating by agitating the resulting combination at a temperature not lower than the melting point of the binder. This method is suitable for production of enzyme-containing granules for use in detergents, medicines, etc. |
