What You Need to Know
Acoustic cavitation generates shear forces >10^6 Pa and transient hot spots that fragment oil droplets while also producing hydroxyl radicals (OH·) that can oxidize unsaturated lipids. Precise control of power density (1–10 W cm⁻²), frequency (20–40 kHz), time (1–5 min) and temperature (<40 °C) is required to balance droplet size reduction with minimal oxidative and thermal damage.
