Description
High‑frequency ultrasound creates cavitation that shatters oil droplets into nano‑sized emulsions.
Technical
Acoustic waves (20–100 kHz) generate cavitation bubbles whose implosion produces intense shear forces that overcome interfacial tension, fragmenting droplets to <200 nm. The process is governed by the balance of acoustic power density, continuous‑phase viscosity, and temperature rise, which can promote free‑radical formation and lipid oxidation if uncontrolled.
