See full technique reference →Rapid nucleation at cryogenic temperatures (<–60 °C) forms microscopic ice crystals (<10 µm), maintaining cell integrity and preventing syneresis. The swift cooling (≈10⁴ K/s with liquid nitrogen) limits enzymatic browning and oxygen exposure, thereby preserving volatile aroma compounds and the purée’s visual quality.
