Abstract

Enzyme granules having an average particle size of from about 1 to about 2.2 mm are disclosed. The enzyme granules comprise an extruded particulate first enzyme component containing at least one enzyme and organic and/or inorganic carrier material and a second particulate enzyme component containing at least one particulate enzyme different from the one enzyme in the said first enzyme component, wherein the second particulate enzyme component is agglomerated onto the particulate first enzyme component, and wherein the average particle size of the particulate first enzyme component is in the range of from about 1.1 to about 3 times the average particle size of the second particulate enzyme component. Furthermore, a process for the preparation of the enzyme granules is disclosed.
