Description
Rapid cooling of a gelatin solution creates a rigid, smooth gel by trapping tiny ice crystals.
Technical
Gelatin dissolves at 60–70 °C, where its triple‑helix chains unwind into random coils. A sudden drop to –80 °C induces rapid refolding and aggregation, forming a three‑dimensional protein network that immobilizes water as micro‑ice, limiting crystal growth below 10 µm. The resulting matrix provides a smooth mouthfeel while maintaining structural rigidity.
