Why freeze drying; because freeze drying is an excellent method for preserving food without preservatives. During processing, foods are first frozen. Then, the water naturally found in foods is gasified under vacuum while it is frozen and removed from the environment.
Water changes from solid to gaseous. This process is called sublimation. Since it is only water removed from the environment, other properties of foods; taste, smell, appearance, color and nutritional values are preserved at a very high level. Freeze-dried products can be stored in closed packages under normal room conditions for years, preserving their real properties.
