Fundamentals of Sound Wave Assisted Extraction
Sound waves provide a powerful mechanical force for extracting essential oils from plant materials through acoustic cavitation. When you apply ultrasonic waves to a liquid medium containing plant matter, you’ll create alternating compression and rarefaction cycles. These cycles generate microscopic bubbles that violently collapse, producing intense local heating and high-pressure shock waves.

You’ll find that frequencies between 20-100 kHz are most effective for plant cell disruption. The extraction mechanisms rely on two primary effects: mechanical impact from cavitation forces and enhanced mass transfer through acoustic streaming. As the waves propagate through the medium, they’ll break down cell walls, allowing better solvent penetration and faster diffusion of essential oils. The process also reduces particle size, increases surface area contact, and accelerates the overall extraction rate compared to conventional methods.
