Open the CIPO recordAbstract From the Canadian patent
The present invention relates to processes for preparing immobilized enzyme, particularly immobilized-starch-degrading enzyme, and reaction product with said immobilized enzyme. More precisely the present processes are based on the invention that an immobilized-starch-degrading enzyme having a high starch-degrading activity is easily obtainable by modifying in solution a starch-degrading enzyme with a modifying reagent in a manner that the enzyme is not insolubilized substantially and adsorbing the modified enzyme onto a carrier. The processes are also based on the finding that reaction products from amylaceous materials can be easily produced with said immobilizedstarch-degrading enzyme.
