Description
Nitrogen freezing uses liquid nitrogen at –196 °C to flash‑freeze protein‑rich foods, preserving texture and flavor.
Technical
The rapid temperature drop induces immediate nucleation of ice crystals, limiting their growth and preventing cellular damage. This halts enzymatic activity and locks in flavor compounds, making it a key technique in high‑end culinary arts.
Science
Primary Reaction
Rapid nucleation and growth of ice crystals at cryogenic temperatures, halting enzymatic activity.
