As expected, the deviation between simulated and experimentally obtained temperature history for the real food items was greater than that for the model food system. This can be attributed to the fact that model food system was homogenous and gelatin is freeze–thaw stable whereas real food system is complex and heterogeneous in nature. As mentioned earlier, the deviation may also be due to high temperature change rate used during DSC study and the assumptions made in the numerical simulation such as simplified food geometry and undisturbed thermocouple location throughout the experiment.
