Der Unterschied zwischen Gefriertrocknung und normaler Trocknung liegt in der Methode, um Feuchtigkeit aus einem Produkt zu entfernen.
Bei der **normalen Trocknung** wird ein Produkt erwärmt, um das Wasser darin zu verdampfen. Dies kann zu Veränderungen in Textur, Geschmack und Nährstoffgehalt führen, und die Hitze kann einige hitzeempfindliche Nährstoffe zerstören.
Bei der **Gefriertrocknung** (auch Lyophilisierung genannt) wird das Produkt zunächst eingefroren. Dann wird der Umgebungsdruck stark reduziert, sodass das gefrorene Wasser (Eis) direkt in Wasserdampf übergeht, ohne die flüssige Phase zu durchlaufen. Dieser Prozess wird als Sublimation bezeichnet. Der Hauptvorteil der Gefriertrocknung ist, dass sie bei sehr niedrigen Temperaturen durchgeführt wird, wodurch die Struktur, der Geschmack, die Nährstoffe und die Farbe des Produkts weitgehend erhalten bleiben. Das Endprodukt ist in der Regel leichter und hat eine poröse Textur, die Wasser leicht wieder aufnimmt.
Freezing the food before drying preserves its appearance. Furthermore, the water is completely removed, which allows for a shelf life of up to 25 years.
