Description
Cryogenic preservation with liquid nitrogen rapidly cools food to −196 °C, arresting enzymatic and microbial activity while minimizing ice‑crystal damage.
Technical
The process involves the instantaneous nucleation of ice crystals as water molecules freeze at extremely low temperatures, halting metabolic reactions and preserving cellular integrity. Rapid cooling reduces ice‑crystal size to sub‑10 µm, limiting mechanical damage and preserving texture and flavor.
