| Research Abstract |
It is important to know suitable heating conditions in cooking processes when foods are boiled, where heat and mass transfer play an important role between food stuffs and surrounding fluids. In the present study, by using a mathematical model for cooking process based on the porous media theory, thermal fluid convection and heat and mass transfer are numerically examined in the foods and surrounding fluids. In comparison with boiling experiments using potatoes and with the help of a one-dimensional model, it is found that preferable sizes of food stuffs for effective heat transfer can exist and solute concentrations and hardness of the food stuffs can predict.
