Abstract: Concentrated enzyme solutions are refined by a process comprising the steps of: (A) providing a concentrated enzyme solution comprised of insoluble solids; (B) separating the insoluble solids to produce a solids-free supernatant solution and (C) contacting the supernatant solution with a strongly basic anion exchanger carried out with a bed volume of from 1 to 10 to produce a decolorized protein solution. No precipitation takes place in the process. Instead, the target enzymes remain in solution throughout the entire process, for which purpose certain concentration ranges are particularly advantageous in regard to the yield to be obtained.

Abstract: An enzyme granule and means for producing the enzyme granule is presented. The enzyme granule is composed of an enzyme, a carrier material, and a coating system of 5 to 70 percent by weight fine-particle inorganic water-insoluble pigment, 45 to 90 percent by weight of a water-soluble organic substance having a melting point of from 40 to 70° C., and 0 to 30 percent by weight of a flow improver. The granule can be produced by mixing an aqueous enzyme liquid with an inorganic or organic carrier material to form an enzyme compound, extruding the enzyme compound, spheronizing the extrudate, and applying an outer coating layer of the coating system listed above to form an enzyme granule having a mean particle size of 0.8 to 1.4 millimeters. The coated enzyme granule has increased storage stability, even coloration, reduced odor, and releases enzyme activity quickly in water. The enzyme granule is useful in solid detergents.
