Ultrasonic extraction uses the multi-stage effects such as the strong cavitation stress effect, mechanical vibration, disturbance effect, high acceleration, emulsification, diffusion, crushing and stirring effects generated by the pressure of ultrasonic radiation, increasing the frequency and speed of material molecules and increasing solvent penetration Penetrating power, thereby accelerating the target ingredients into the solvent and facilitating the extraction

Ultrasound is an elastic mechanical vibration wave, which is fundamentally different from electromagnetic waves. Because electromagnetic waves propagate in a vacuum, ultrasonic waves must propagate in the medium. When passing through the medium, the entire process of expansion and compression is formed.
In liquids, a negative pressure is created during the expansion process. If the ultrasonic energy is strong enough, the expansion process can create bubbles in the liquid or tear the liquid into small cavities. These cavities are closed instantaneously, and an instantaneous pressure of up to 3000 MPa is generated when the cavity is closed, which is called cavitation.
Cavitation refines substances and makes emulsions, accelerates target ingredients into solvents, and improves extraction rates. In addition to cavitation, many secondary effects of ultrasound are also beneficial for the transfer and extraction of target components
The above-mentioned effect of ultrasonic waves is very effective in extracting various target components from different types of samples.
The high temperature and pressure generated on the contact surface between the organic solvent and the solid substrate by applying ultrasonic waves, plus the oxidizing energy of the free radicals generated by ultrasonic decomposition, etc., thereby providing high extraction energy.
