Change of radial temperature distributions in a baked sweet potato and roasted fish were visualized by a thermography camera. The temperature distribution in the heated food was same as calculated value by unsteady heat transfer theory, when the temperature of the food was lower than 65 degree C. When the food was heated up above 65-70 degree C, the temperatures was different from calculated value. The temperature distribution at the outer part of the food was steeper than the predicted value. On the other hand, temperature distribution at the inner part of the food was flattened than the original value. It was thought that the outer part of the food was baked and acted a thermal insulation wall, and that heat was transferred rapidly by vapor transmission through the cells in the food at the center part of the food.
