Lyophilization
Lyophilization was a question on "Who Wants to be a Millionaire" today.
I didn't know that it means freeze drying, so I looked it up.
In the process they freeze the food and put it under high pressure.
The water (now ice) sublimates to a gas and is drawn off.
You are left with food that is 90% smaller by weight and about the same volume.
