Description
Super‑freezing rapidly cools food to sub‑–80 °C to produce tiny ice crystals and preserve texture and flavor.
Technical
The process relies on rapid nucleation of ice crystals, limiting their growth to sub‑0.5 mm. This minimizes mechanical damage to protein structures while maintaining the integrity of cellular membranes. The resulting protein conformations are stabilized by the sudden drop in temperature, reducing denaturation and preserving sensory qualities.
