| Research Abstract |
In the case of meat or fish meat cooking under the high temperature, lack of heating can result in the proliferation of microorganisms harmful to humans, while excessive heating may lead to the production of new harmful substances that is a heterocyclic compound. Thus it is important to predict various changes that may occur in food materials based on heat transfer phenomena, and to optimally control cooking. To clarify the influences of the protein denaturation degree on the cooked meat qualities, namely, the texture and the state of water, we predicted changes of denaturation degree during heating based on the 3D finite element heat transfer analysis and reaction kinetics. Moreover, changes in browning color at the surface of the food play an important role in quantifying the degree of cooking process and for the monitoring of excessive heating. The influence of the heating medium on the browning color during the grilling process of the fish samples was analyzed by the use of two different heating systems : far-infrared radiation(FIR) and SHS heating, as well as three heating mediums : SHS, Dry-air, and Nitrogen(N_2). Comparison of estimated color, using same surface temperature under FIR and SHS heating, resulted in a slower reduction of L^* value using SHS than FIR.
