Description
Foam creation stabilizes air bubbles using surface-active proteins and surfactants, while calcium‑alginate gelation locks bubbles for aerated spherification.
Technical
Proteins such as ovalbumin denature between 45–70 °C, forming a visco‑elastic film that traps air. Surfactants like lecithin lower interfacial tension below 30 mN m⁻¹, creating micro‑foams. Calcium‑alginate cross‑links in the presence of Ca²⁺ to form a gel that encapsulates gas bubbles.
