Liofilizacija

Liofilizacija ali sušenje z zamrzovanjem je postopek, s katerim odstranimo vodo iz bioloških in organskih snovi, ki bi jih s segrevanjem poškodovali, hkrati pa ohranimo njihovo strukturo in sestavo. Postopek je počasen in porabi 3-krat več energije kot konvencionalno sušenje, zato ga uporabljamo le za občutljive in drage produkte. Liofilizacija temelji na zamrznitvi vode, čemur sledi zmanjševanje tlaka in dodajanje dovolj velike količine toplote, da zamrznjena voda v materialu sublimira neposredno iz trdnega v plinasto agregatno stanje.
