PURPOSE: To contrive to stabilize an enzyme without adding casein, polyhydric alcohol, saccharide, etc., to capsule as one does in a conventional method, by sealing an enzyme such as protease, lipase, lysozyme, etc., and a dispersant within capsule.

CONSTITUTION: An enzyme such as protease, lipase, lysozyme, etc., and a dispersant are sealed within capsule. A wall material for capsule differs depending upon purpose of use of capsulated enzyme-containing preparation, dispersant of enzyme, characteristics of product, kind of enzyme sealed, etc., and any material which is stable to the enzyme sealed in the capsule and to composition of product to be blended with the capsulated enzyme, releases the enzyme, etc., sealed in the inside to the outside by destruction by stress or dissolution in water in use and shows effective activity, may be used.
