A model for freeze concentration and glass transition of carbohydrate solutions as determined by differential scanning calorimetry
Zoltán Kántor, Guido Pitsi, Jan Thoen
Differential scanning calorimetry (DSC) is a common method for the determination of certain thermophysical properties of matter, such as phase transition heat, specific heat, or phase and glass transition temperatures. In particular, the freeze concentration and glass transition of carbohydrate solutions have been extensively studied by DSC. In order to verify the reliability of differential scanning calorimetry in the characterisation of such processes, the correct assignment of the features of the DSC curves to real physical effects is essential.
