| Research Abstract |
The thermal conduction induced close to the cooling plane was detected precisely along the one-dimensional axis in a variety of solidified foodstuffs. In all the cases of cooling procedure in this study, the cooling down has commenced in a rapid process in the sample, and the cooling process has then gradually shifted to the slow stage. The cooling has been suspended finally from the procedure. All of the cooling pattern obtained with solidified foods can simply be recognized as the 'relaxation phenomenon' without any noise caused by the phase change of the component in the sample. Such the cooling behavior of foods is quite different from the heating procedure of foodstuffs. Thus, the cooling procedure of foodstuffs can simply be recognized as the relaxation process of thermal energy with the relaxation time.
