Cylindrical liquid can of water and CMC was simulated by solving the governing equations for continuity, momentum and energy conservation, using “COMSOL®” multiphysical coupling field software package which based on finite element method of analysis. Through finding out cold spot of 100 °C, 105 °C，110°C and 115°C in the can and sterilization minimum value spot, temperature and sterilization value were compared. The results indicated that there were differences between cold spot and F minimum value spot. thus, in order to ensuring food safety, the original sterilization time should be moderately prolong, especially for thinlyfluid.
