*3.5. Differential Scanning Calorimetry (DSC) of Glucans*

The calorimetric curves recorded for the glucan samples are very similar. Both mainly presented an endothermic peak (1) near 125 ◦C and a glass transition (TG) between 150 and 220 ◦C (Figure 4).

Peak one of the GZ samples had an enthalpy value (E = 115.8 J/g) significantly higher than that recorded for the same peak of the GM samples (E = 52.3 J/g). The enthalpy of fusion was closely related to the degree of crystallinity. A higher value corresponded to a greater interaction between the molecules, and there was more interaction between the molecules in the GM samples than in the GZ samples.

Inflection points typical of glass transition (TG) [34] were present in both samples, but GZ samples had a higher TG (246.0 ◦C) than the GM samples (TG = 180.5 ◦C).
