What is freeze-drying?
Freeze-drying (lyophilization) is accomplished by sublimation of ice in a vacuum. The basic elements of this process have been known for over 70 years. However, it was not until World War II that much emphasis was placed on the refinement process. During this time, much attention was given to the development of equipment and techniques for the purpose of supplying large quantities of dried blood plasma and penicillin to the armed forces. By the end of the war, freeze-drying had become known as a near-perfect method of preservation.
