OVERVIEW OF FREEZE – DRYING PROCESS
Freeze-drying is a process where the natural products are frozen and then placed into a vacuum. The ice crystals formed in the product are then sublimated into water vapor, while the cell structure of the original product remains intact. Freeze dried products retain their original nutritional value, texture, shape and taste. The end product is as fresh as the original food, with just the water removed! When re-hydrated with water, it rehydrates to resemble the original natural product.
