Cryogenic sous‑vide uses liquid‑nitrogen or sub‑zero baths to flash‑freeze or tenderize proteins while preserving cellular structure and preventing enzymatic degradation.
Origin: French molecular gastronomy chefs (early 2000s) — France
See full technique reference →At temperatures below –80 °C, water molecules form tightly packed ice crystals that immobilize cellular contents, halting enzymatic reactions. The extreme cold also suppresses lipase activity, preserving fat integrity and preventing rancidity. Controlled thawing at –20 °C to –80 °C allows proteins to rehydrate without denaturation, maintaining juiciness and texture.
Primary Reaction
