Description
Cryogenic ice crystal engineering uses ultra‑rapid freezing to produce sub‑10‑µm ice crystals, preserving cell integrity and texture.
Technical
Rapid cooling at –196 °C or higher rates (>10 000 °C/min) limits ice crystal nucleation and growth, thereby preventing cellular rupture. The process also suppresses enzymatic activity and lipid oxidation, maintaining protein structure and flavor compounds. Controlled storage at –80 °C for months preserves the frozen state without recrystallization.
