Introduction to Ultrasonic Extraction

Ultrasonic extraction, also known as sonication, is a process that utilizes high-frequency sound waves to agitate particles in a sample, facilitating the release of bioactive compounds. This technique is widely used in various industries, including pharmaceuticals, food processing, and in the recovery of natural products.

Principles of Ultrasonic Extraction

The core principle behind ultrasonic extraction is the application of ultrasonic waves, typically in the range of 20 kHz to 40 kHz. These waves create cavitation bubbles in the liquid medium, which upon collapse, generate microscopic shock waves and high shear forces. These forces disrupt cell walls and membranes, releasing desired intracellular compounds into the surrounding medium.

Key Parameters in Ultrasonic Extraction

Frequency

Frequency is a critical parameter, impacting the formation and collapse of cavitation bubbles. Commonly used frequencies range between 20 kHz and 40 kHz. Lower frequencies generate larger cavitation bubbles, increasing mechanical effects but reducing the number of bubbles. Higher frequencies produce more bubbles with less aggressive physical impact.

Amplitude

Amplitude refers to the displacement of the ultrasonic probe, directly affecting the intensity of the ultrasonic waves. Higher amplitudes lead to more violent cavitation, enhancing the extraction efficiency. Typical amplitudes range from 10 micrometers to 100 micrometers, adjustable according to the material's toughness.

Temperature

The temperature of the processing medium can influence the efficiency of the extraction. While higher temperatures generally increase solubility and diffusion rates of compounds, they can also potentially degrade sensitive bioactive compounds. Optimal extraction often occurs between 20°C and 60°C, depending on the stability of the target compounds.
