Freeze‑drying removes water from sauces by sublimating ice under vacuum, preserving flavor and structure.
Origin: NASA and US military (1960s) — United States
See full technique reference →During primary drying, ice sublimates at temperatures below the ice point while under low pressure, preventing protein denaturation. Secondary drying removes bound water by heating at mild temperatures under vacuum, ensuring low moisture content and stability.
Primary Reaction
Ice → Water vapor (sublimation)
