Description
Ultrasound-assisted extraction uses acoustic cavitation to disrupt plant cell walls, enhancing mass transfer of target compounds.
Technical
Acoustic cavitation generates microbubbles that collapse violently, producing localized high temperatures and pressures, shear forces, and microstreaming that break cell walls and facilitate solvent penetration. The resulting microjets and shock waves increase the surface area and create transient pores, allowing bioactive molecules to diffuse rapidly into the extraction medium.
