Freeze-drying of emulsions--influence of congealing on granulometry research of a cryoprotective agent.
Emulsions of three different size distributions and five oil/water ratios of the finest of these distributions were congealed according to three different congealing processes before the freeze-drying operation. The influence of the various cryoprotective agents added was studied and the size change of the dispersed phase after congealing was examined.
