Adsorption isotherm of amorphous trehalose

The water adsorption isotherm at 25°C of freeze-dried amorphous trehalose and trehalose with the addition of maltodextrin (MD) DE 10.9 was obtained. Moisture uptake as a function of time at various relative humidities (RH) was also measured. At low relative humidities (RH) amorphous trehalose adsorb...
