  • Immobilized enzyme catalyst
    Patent number: 4259445
    Abstract: An enzyme catalyst is described. The catalyst comprises subcellular particulates of vegetable material containing an enzyme system composed of different carbohydrate transforming enzymes. These particulates are encapsulated within a matrix formed by coagulating an organic entrapping agent with polyvalent cations. The matrix is permeable to permit access of carbohydrate substrate to enzyme and acts to immobilize the enzyme system and preserve the activity of the encapsulated enzymes.
