WebResults: When an aqueous solution containing trehalose (4% w/v) and mannitol (2% w/v) was cooled to -40°C at 0.5°C/min, hexagonal ice was the only crystalline phase. However, upon warming the sample to the annealing temperature (-18°C), crystallization of mannitol hemihydrate was readily evident. WebPurpose: (i) To study the crystallization of trehalose in frozen solutions and (ii) to understand the phase transitions during the entire freeze-drying cycle. Method: Aqueous trehalose solution was cooled to -40°C in a custom-designed sample holder.
