Description
A pressurized siphon creates a stable protein‑stabilized foam by dissolving CO₂/N₂O into a chilled liquid.
Technical
Under 0–5 °C, CO₂ or nitrous oxide dissolves into the aqueous phase, lowering surface tension and allowing micrometer‑sized bubbles to nucleate. Simultaneously, pressure‑induced protein unfolding and Maillard‑like cross‑linking form a viscoelastic film that stabilizes the bubbles. Temperature, pressure, and protein concentration govern foam longevity and texture.
