- Cavitation effect: When ultrasound propagates in a liquid, it undergoes cyclic changes of compression and sparsity, leading to the formation of small bubbles inside the liquid and rapid collapse. This process is called cavitation. The strong shock waves and shear forces generated during the cavitation process can damage the plant cell wall, thereby releasing bioactive substances within the cell.
- Mechanical effect: When ultrasound propagates in a medium, it generates high-frequency vibrations, damaging plant cell walls and membranes, and promoting the release of target components from cells into the extraction solvent. Meanwhile, ultrasound can also cause rapid vibration and collision of medium molecules, thereby improving the solubility and diffusion rate of solvents towards target components.
- Thermal effect: Although ultrasonic extraction is usually carried out at lower temperatures, a certain amount of heat is still generated when ultrasonic waves propagate in the medium. This heat helps accelerate the dissolution and diffusion process of the target component, thereby improving extraction efficiency.
Considering the above three effects, ultrasonic extraction technology can effectively extract bioactive substances in a short period of time while maintaining their natural structure and biological activity. In addition, ultrasonic bioactive extraction has the advantages of simple operation, mild extraction conditions, and low solvent usage, and is widely used in fields such as pharmaceuticals, food, and cosmetics.

Other application scenarios for ultrasonic bioactivity extraction
1, Extraction of active ingredients from traditional Chinese medicine
Ultrasonic extraction machines have significant advantages in extracting effective ingredients from traditional Chinese medicine. Through extraction experiments on different Chinese medicinal materials, it was found that ultrasonic extraction machines can effectively extract effective components from Chinese medicinal materials with a high extraction rate. Meanwhile, ultrasonic extraction can also damage the cell wall of medicinal herbs, accelerate the release and diffusion of effective ingredients, and improve extraction efficiency.
2, Food industry
Ultrasonic extraction machines are also widely used in the food industry. For example, ultrasonic extraction technology can be applied to the extraction of plant active ingredients and animal proteins. The active ingredients of plants mainly include flavonoids, saponins, polyphenols, etc., which have antioxidant, anti-inflammatory, and anti-tumor effects. Animal protein mainly includes collagen, whey protein, etc. These proteins can be efficiently extracted through ultrasonic extraction technology.
3, Natural Flavor Extraction
Ultrasonic extraction machines can also be applied to the extraction of natural spices. The effective components of spice plants usually have high volatility, and traditional extraction methods can easily lead to loss of volatile components. Ultrasonic extraction technology can extract at low temperatures, avoiding the loss of volatile components and effectively extracting aroma components from plant cells.
