PURPOSE: To simplify and stabilize the generation of oxygen and enable dissolution rate of hydrolase in water to be controlled by using a dried granular hydrolase formed to be dried after excipient and binder are added to the hydrolase and they are mixed with each other and are granulated.

CONSTITUTION: As a hydrolase, a dried granular body formed to be dried after excipient and binder are added to the hydrolase and they are mixed with each other and are granulated, is used. Besides, as the hydrolase, the pressure consolidated one of the granular dried body formed to be dried after the excipient and the binder are added to the hydrolase and they are mixed with each other and are granulated, is used. As engyme for cracking hydrogen peroxide, powdered catalase sold as engyme agent in a food industry field is used. The catalase is easily crystallized and is obtained to be crystallized from livers, red blood cells, germs, and the like, and is the substance having a molecular weight of about 225000. As a result, a granular structure, and decomposition and dissolution rates in water can be regulated, and the hydrolase is easily handled.
