Generalized linearization of kinetics of glucose isomerization to fructose by immobilized glucose isomerase.
The kinetic parameters of both glucose isomerization to fructose and immobilized glucose isomerase (GI) inactivation calculated under different conditions are compared and discussed. Utilizing these figures, the possibility of generalizing a linear model, previously proposed for the kinetics of glucose isomerization by immobilized glucose isomerase, is investigated, so as to apply them to whole ranges of temperature and concentrations of actual interest in industrial processes. The proposed model is a satisfactory approximation of the more involved Briggs-Haldane approach and substantially simplifies the problem of optimizing an industrial fixed-bed column for high-fructose corn syrup (HFCS) production.
