Patent ID: 7807428

Claim:
A method for producing an immobilized enzyme which comprises the steps of i) immobilizing an enzyme used for hydrolyzing fats and oils on a immobilization carrier having a particle size of from 100 to 1000 μm in diameter and a pore size is from 10 to 150 nm by adsorption, ii) adjusting the moisture content of the immobilized enzyme to from 1 to 20% by weight based on the weight of said carrier by bringing said immobilized enzyme into contact with 100 to 3000% by weight based on the weight of said carrier of an organic solvent in which 10 to 200% by weight based on the weight of said carrier of fat-soluble fatty acids or derivatives thereof have been dissolved, for a contact time of from 1 to 30 minutes, wherein said fat-soluble fatty acid is a saturated or unsaturated fatty acid with 8 to 18 carbon atoms with a linear or a branched chain.
