Abstract
The thermal transitions of α,α-trehalose polymorphs have been carefully studied by differential scanning calorimetry (DSC) at different scan rates. Attention has been paid to the correlation of the thermal data with the proper crystalline forms (when present), in order to attribute the observed transitions correctly. In particular, the subtle dehydration process of dihydrate trehalose has been already shown to produce several species, depending on the experimental conditions.
Thermodynamic data (i.e., temperatures and enthalpies) for all the known transitions are reported and the results are critically discussed.
