Description
Whipping chilled aquafaba at moderate speed creates a stable, airy foam that mimics egg‑white meringue.
Technical
Heating aquafaba to 30–45 °C partially denatures chickpea globulins and albumins, exposing hydrophobic residues that enable interfacial adsorption at air–water interfaces. Rapid shear (≈250 rpm) unfolds these proteins, allowing them to form a viscoelastic network that traps air bubbles; added sucrose increases continuous‑phase viscosity, further stabilizing the foam, while low‑level salt screens electrostatic repulsion, fine‑tuning bubble coalescence.
