Claim:
1. A purified lipase powder composition which comprises a cellulose filter aid(s) and a product obtained by pulverizing a Thermomyces sp.-derived lipase immobilized to a silica carrier(s) wherein the filter aid(s) is/are powdery and has/have an average particle diameter of 10 to 90 μm, wherein the average particle diameter of the resulting pulverized product is 1 to 90 μm, wherein the mass ratio of the pulverized product to the filter aid(s) is 1/7 to 2/1, wherein such purification occurs by contacting at least one long chain fatty acid triglyceride having 14 to 24 carbon atoms in a constituent fatty acid and at least one medium chain triglyceride having 6 to 12 carbon atoms in a constituent fatty acid, and wherein said purified lipase powder composition has improved lipase activity relative to lipase powder compositions that have not been purified using said long chain fatty acid triglyceride and said medium chain triglyceride.
