Abstract
A process for producing an immobilized enzyme composition comprises simultaneously reacting a non-proteolytic enzyme and a water soluble-multifunctional reagent with a non-hardened granular gelatin in an aqueous medium wherein the reacting is carried out in the presence of a water-soluble protein polymer compound in an amount of from 0.01 to 2 parts by weight relative to one part of the non-proteolytic enzyme. The non-proteolytic enzyme forms a uniform film on the surface of the granular gelatin and the bond between the non-proteolytic enzyme and the granular gelatin is strengthened by the water soluble protein polymer.
