Method for producing lipase powder compositions

A method for producing a ground product of a lipase powder composition comprising an immobilized lipase in which a lipase derived from Thermomyces sp. is immobilized to a silica carrier and a cellulose powder wherein the cellulose powder has an average particle diameter of 10 to 90 μm, the method comprising the steps of wetting the cellulose powder with oil;

• removing part of the oil from the cellulose powder wetted with oil so that the amount of oil remaining in the oil-containing cellulose powder is 1 to 1.4 times the mass of the cellulose powder before oil wetting;
• mixing the oil-containing cellulose powder and the immobilized lipase at a ratio of 0.45:1 to 0.85:1 based on mass of the cellulose powder and the immobilized lipase before oil wetting;
• and grinding the obtained mixture, the steps being conducted in the above order.
