Description
Foamification with nitrogen oxide creates airy microbubbles in liquids by dissolving N₂O under pressure and releasing it rapidly.
Technical
When N₂O dissolves in a liquid at sub‑zero temperatures and 2–3 bar pressure, it forms a supersaturated solution. Upon pressure release, the gas expands, nucleating microbubbles that are stabilized by surfactants such as lecithin or xanthan gum. The resulting foam has a fine bubble size distribution (10–30 µm) that delivers a smooth, mousse‑like mouthfeel.
