LYOPHILISATION

Lyophilisation, also known as freeze-drying, is a process where products are dried carefully. Thereby water of the frozen product dries by sublimation. This means that ice crystals go directly to gaseous state without a liquid phase occurring. The nutritive value of resulting product is the same as that of fresh product. Lyophilisation is used for drying of organic wild berries and fruits (wild bilberries, wild lingonberries, raspberries, wild blackberries, strawberries, aronia, cherries, sour cherries).
