freeze-drying
Sublimation-based preservation method
Freeze-drying is a preservation method that removes moisture by freezing a substance, then reducing pressure so the ice sublimates directly into vapor without passing through a liquid state.
The process preserves structure, flavor, and nutrients better than conventional drying.
Freeze-dried foods are lightweight and shelf-stable: freeze-dried strawberries, freeze-dried coffee.
The technique also preserves biological samples and pharmaceuticals.
