Description
Liquid‑nitrogen flash‑freezing instantly solidifies fruit purées at ‑196 °C, creating ultra‑fine ice crystals that lock in flavor and inhibit enzymatic degradation.
Technical
The rapid temperature drop causes homogeneous nucleation of water, producing ice crystals <10 µm that encapsulate volatile aroma compounds. This vitrification arrests enzymatic activity, preserving the purée’s sensory profile for extended storage. The resulting matrix is ideal for subsequent spherification, as the frozen structure resists diffusion of calcium ions.
