Ultrasound has a higher frequency (20 kHz~2 MHz) than a human's audible frequency (20 Hz~2 kHz). The advantages of using ultrasonic waves for extraction were well studied and developed by our researchers. Some active compounds are vulnerable to heat and easily destroyed at high temperatures. Ultrasonic waves can effectively extract these active Ingredients at a lower temperature. The waves penetrate deep into the raw materials to extract the active ingredients.

Advantages of Ultrasonic Extraction Process:

- Facilitate swelling and hydration of raw materials
- Increase the extraction yield
- Improvement in efficiency and speed
- Processed at a lower operating temperature
