The methods of this study were to use the heat treatments included hot air, hot water and steam to prevent decay. We measured the temperature in 5 mm depth of the surface on sweet potato in heating treatments and also used COMSOL Multiphysics to simulate the process and to predict surface temperature that was undetectable during heating process to insure the effeteness of heat treatments. After heating treatments, sweet potato were stored in cold rooms at 13~15℃ and 85~100%.
