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.

ADVANTAGES OF FREEZE – DRYING PROCESS

1) The original shape and size of the product is unchanged.
2) Easy to transport due to its light weight.
3) Easy to store at room temperature.
4) Long shelf life (up to 2 years).
5) No preservatives or additives, thus good for health.
6) Original nutrition is retained in the end product.
7) Easily rehydrated with water/milk.
