Mechanical glass transition temperature

|Abstract:||Glass transition temperatures and water activity as a function of moisture content were determined for freeze-dried shark to further compare the two distinct criteria of food stability. The adsorption experiments were carried out at controlled water activity, at 21, 40, and 50°C using an isopiestic method and they were modeled using BET and GAB equations. Glass transition temperatures were measured by dynamic oscillation on shear. Results indicate that there is a difference in the temperature-related stability criteria predicted by the concepts of water activity (aw) and the glass phenomenon (Tg). The glass transition concept tends to accommodate higher levels of moisture within the framework of a safe storage of a dried product.|
