Description

The freezing and the melting processes of the solutions of trehalose and water were observed to know how trehalose protects the organisms from the freezing of their cellular water. The frozen specimens that were frozen rapidly at more than 10K supercooling showed the ramera structure composed of the ice phase and the trehalose rich phase. The specimens' surfaces were covered with the trehalose rich phase and very smooth. Melting of the specimens firstly began at the trehalose rich phase. The frozen specimen of 41.7wt% trehalose solution was soft enough to slide rapidly along the interface between the ice phase and the trehalose rich phase at -17℃.
