Answer to Question 1

The principle of freeze-drying is that under conditions of low vapor pressure (a vacuum), water evaporates from ice without the ice melting.

Answer to Question 2

Ultrafiltration is a membrane filtration process operating at 2 to 10 bars (international unit of pressure equal to 29.531 in. of mercury at 32F) pressure and allowing molecules the size of salts and sugars to pass through the membrane pores, while molecules of the size of proteins are rejected.
