摘要: A three-step complex formation of fructose by glucose isomerization was suggested to describe the kinetics. The model characterized a complex. Experimental data obtained from process using immobilized Sweetzyme enzyme, IT® were used in this study. Experiments conducted at different reaction temperatures range 50-70°C and initial concentrations 10, 15 20% enzyme loading 1g. Glucose dropped with time until equilibrium reached. first order kinetics for steps employed Runge Kutta 4th algorithm combined least square method estimate pre-experimental factor activation energy determination corresponding rate constants solving value problem EZ-Solve software. Very good fits between experimental prediction obtained.
