Another term for freeze-drying is

B) dehydration.
C) filtration.
D) pasteurization.
E) lyophilization.

Accepted Answer

Freeze-drying and lyophilization are interchangeable terms used to describe the same process. It involves removing water from a substance by freezing it and then subjecting it to a vacuum, causing the ice to sublimate directly to gas, leaving the substance dry. Radiation, filtration, and pasteurization are all different processes and not alternatives to freeze-drying.
