Description
Siphon-based foamification creates airy foams by dissolving nitrous oxide into a chilled liquid and releasing it to nucleate bubbles, stabilized by proteins or hydrocolloids.
Technical
When a sealed canister is charged with N₂O at ~800 psi, the gas dissolves into the liquid according to Henry’s law. Upon valve opening, the sudden pressure drop causes the dissolved N₂O to nucleate into microbubbles, and surface-active proteins or hydrocolloids adsorb to the bubble interfaces, forming a viscoelastic film that resists drainage and coalescence. Temperature and fat content modulate gas solubility and interfacial film integrity, thereby controlling foam stability.
