Whereas the first-order kinetic model of two-component system was applied to investigate the thermal pasteurization of mango juice and the commercial Mathcad program package was also used to calculate the necessary parameters from the experimental data for the model. Results indicated that the thermostable and thermolabile pectinesterase (PE) components containing in the juice were 41% and 59%, respectively. The Z value of thermostable (Zs) and thermolabile (Zl) of thermal destruction curves for the average thermostable PE and thermolabile PE were 14.65°C and 15.94°C for the temperature range of 80~85°C, respectively. The calculated and experimental linear thermal pasteurization curves for mango juice were in good agreement at a wide range temperature of 80~90°C. |
