The instrument
method used for the determination of Tg is differential
scanning calorimetry (DSC) that detects the change in heat
flow of the amorphous component between glass and rubbery
states occurring over the transition temperature range.
The DSC technique was used to obtain heat flow versus temperature
thermograms (Fig. 11). Glass transition temperature
is observed as an endothermic stepwise change in the heat
flow (Jaya and Das, 2009). In this study the highest drying yield
and Tg point refers to the powder produced with the blend of
maltodextrin 6DE and gum Arabic. It is in agreement with the
results of
