Abstract  

Differential scanning calorimetry (DSC) was used to determine phase transitions of freeze-dried camu-camu pulp in a wide range of moisture content. Samples were equilibrated at 25°C over saturated salt solutions in order to obtain water activities (aw) between 0.11–0.90. Samples with aw>0.90 were obtained by direct water addition. At the low and intermediate moisture content range, Gordon–Taylor model was able to predict the plasticizing effect of water. In samples, with aw>0.90, the glass transition curve exhibited a discontinuity and Tg was practically constant (–58.8°C), representing the glass transition temperature of the maximally concentrated phase(Tg ).
