Ultrasonic topic: "Ultrasonically Intensified Solvent Extraction"
Ultrasonication intensifies conventional solvent extraction and makes the process significantly more efficient. Ultrasonic extraction works with various types of solvents such as water, ethanol, methanol, isopropanol, vegetable oils, glycerin to name just a few. Ultrasonically generated cavitation improves mass transfer and disrupts cells so that the intracellular material and the targeted bioactive substances are released into the solvent. As a non-thermal extraction method, sonication prevents the thermal degradation of thermo-labil ingredients. Thereby, ultrasonic extraction increases the yield, improves extract quality and speeds-up the process.
