Abstract
An immobilized enzyme preparation is disclosed which comprises a gelling agent which has been cross-linked and active carbon in an amount of 1 to 3%. The gelling agent may be egg white chitosan or alginate. The enzyme glucose isomerase may be employed. When used in packed bed columns in enzymatic glucose isomerization processes, the disclosed immobilized enzyme formulation allows for a bedheight that is twice as high, a syrup flow that is doubled, or a doubled syrup viscosity when compared to formulations without carbon.
