Description
Ultrasonic foamification uses high‑frequency acoustic waves to generate cavitation bubbles that collapse, entraining gas into a protein‑rich liquid to form a stable foam.
Technical
The collapse of cavitation bubbles produces intense shear and micro‑jets that disperse gas into the liquid, while the resulting turbulence promotes rapid adsorption of surface‑active proteins at the gas–liquid interface. The mechanical energy also induces partial unfolding of proteins, increasing their interfacial activity and creating a viscoelastic film that stabilizes the foam. The process is highly controllable, allowing precise tuning of bubble size, foam density, and stability through frequency, amplitude, and temperature adjustments.
