Web1 feb. 2007 · The kinetics of sucrose hydrolysis over Amberlite IR-120 has not been reported to date. Therefore, we could not directly compare the calculated values of kinetic parameters with those from the ... WebOther investigators (1, 6, 8) have determined velocity constants for lactose hydrolysis in the presence of various quantities of acid and at tem- peratures below 100 ° C. Armstrong and Caldwell (1) hydrolyzed 18 per cent lactose with 0.5 molar HC1 at 99 ° C. and found K × 104 = 334.2. Polari- scopic methods of analysis were used.

Exploring the Hydrolysis of Sucrose by Invertase Using Nuclear …

Web22 apr. 2010 · This work describes the experimental determination of sucrose hydrolysis kinetics using a heterogeneous catalyst. We used an Amberlite IR-120 strong acidic cation-exchange resin. The experiments were performed under previously determined optimal process conditions: sucrose mass concentration, γ S = 50 g L−1, catalyst mass … WebMathematical Model. Sucrose (S) enzymatic hydrolysis into glucose (G) and fructose (F) has been modeled as an unsteady-state process, providing a pressure drop between inlet and outlet sections of a tubular reactor of radius R = 0.04 m and length L = 0.3 m, causing a laminar flow with average velocity v m. ic 3639
