Abstract The enzymatic isomerization of glucose to fructose is attracting significant attention from scientific as well as industrial quarters. In recent years, high fructose syrups (“isosyrups”) produced by enzymatic isomerization of high DE‐syrups have been introduced successfully, primarily in the U.S.A. A decisive factor for the ability of isosyrups to compete is enzyme costs. The development of immobilized glucose isomerase makes multiple use of the enzyme possible and thus makes the economy of the isomerization process more attractive. Sweetzyme is the trade name of an immobilized glucose isomerase. The enzyme is presently being marketed for batch/re‐use isomerization. A special quality suited for continuous column plug‐flow isomerization is under development. The properties of the two qualities and conditions for use in batch and column isomerization processes are described.
