Radial Temperature Distribution in a Heated Food

Abstract

Radial temperature distribution in a heated food (baked sweet potato, roasted fish and a slice of bread) was visualized by an infrared camera. The temperature distribution in those heated foods were different from predicted value when the food was heated up above 65-70 degree C. The temperature distribution at the outer part of the food was steeper than the predicted value. Temperature distribution at the inner part of the food was flattened than the predicted value.
