külmkuivaid
Külmkuivaid refers to freeze-dried products, a dehydration process that involves freezing the material and then removing the water content in a vacuum. This method preserves the product's nutritional value, flavor, and texture to a significant extent compared to other drying techniques. The process begins by freezing the food item, which turns the water within it into ice crystals. Subsequently, the frozen item is placed in a vacuum chamber. Under these low-pressure conditions, the ice sublimates directly into water vapor, bypassing the liquid phase. This sublimation allows for the removal of moisture without causing significant damage to the cellular structure of the food.
Freeze-dried products are typically lightweight, have a long shelf life, and are easily rehydrated by simply
