Freeze-drying is a process for extracting liquid from a product. It is the most gentle way to remove water from food. 

Freeze-dried products have the advantage that they retain their shape and structure relatively unchanged from fresh condition. They absorb water again better than air-dried products and retain more of their original taste and aroma. When vacuum packed, they can last for a very long time, even without the use of preservatives.

Freeze drying is an exciting process. Water or other solvent is removed by a process called sublimation. Sublimation occurs when the ice in a frozen product is converted directly to gaseous form without passing through the liquid phase.
Spartabutikk has further developed the freeze-drying technology, to deliver the best possible result, every time.
