Description
A rapid temperature drop that limits crystal growth, yielding fine, uniform crystals in fats, sugars, and ice‑cream mixes.
Technical
The shock forces a high nucleation rate while suppressing crystal growth, stabilising the thermodynamically favoured Type I β‑V crystals of cocoa butter and fine sucrose lattices. In ice‑cream mixes the rapid freeze creates sub‑50 µm ice crystals, preventing ice‑crystal coalescence. The controlled temperature window (e.g., 31 °C → 27 °C for chocolate) locks in the desired polymorph and prevents formation of larger, less stable crystals.
