Freeze-drying, also known as lyophilization or cryodesiccation, is a process used for the dehydration most heat-sensitive materials and aromas. Freeze-drying works by freezing the material, reducing the surrounding pressure, and adding enough heat to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase.
