Claim Text:
1. A method of preparing stabilized catalase enzyme comprising the steps of mixing a substrate comprising microcrystalline cellulose powder, a buffer, and catalase enzyme having a molecular weight of less than 500,000 Daltons to create a mixture including solids and liquid, draining the liquid from the mixture, rinsing the solids with water, thoroughly mixing the solids with polyvinyl alcohol, and drying the mixture to create a powder, wherein the stabilized catalase enzyme exhibits a decreased loss in catalase activity compared to catalase enzyme not mixed with the substrate and the polyvinyl alcohol, wherein the stabilized catalase enzyme has an activity at 25° C. between 500 IU/g and 1,000,000 IU/g, and wherein the stabilized catalase enzyme is stable for up to 16 weeks at 35° C. after thermal cycling of the stabilized catalase enzyme at 40° C. for 72 hours and 55° C. for 6 hours.
