SO EXACTLY WHAT IS FREEZE-DRYING?
So glad you asked! This is the question everybody has!
Freeze drying is a low temperature dehydration process that involves freezing the product and lowering pressure, thereby removing the ice by sublimation. This is in contrast to dehydration by most conventional methods that evaporate water using heat.
