Utrasonic topic: "Sonication - Applications and Advantages"
Sonication (also termed ultrasonication) is the application of low frequency, high intensity ultrasound waves into a liquid or pastes medium. Acoustic cavitation generated by intense sonication creates energy-dense conditions such as high pressure and temperature differentials as well as high shear forces and turbulences. Those ultrasonically generated forces break particles and droplets, disrupt cells and initiate chemical reaction. Due to these effects, sonication is used for homogenisation, wet-milling & dispersing, emulsification, extraction and sonochemistry. Read more about the manifold advantages of sonication and learn how your process can benefit from the application of power ultrasound!

Biosynthetic Production of Human Milk Oligosaccharides
The biosynthesis of human milk oligosaccharides (HMOs) via fermentation or enzymatic reactions is a complex, consuming and often low-yielding process. Ultrasonication increases the mass transfer between substrate and cell factories ans stimulates cell growth and metabolism. Thereby, sonication intensifies…

Efficient Production of Hops Extracts by Sonication
Hops and hop extracts are essential ingredients for the production of beer. The alpha-acids a-caryophyllene (humulone) and beta-caryophyllene (humulene) are important flavour compounds, which give beer its bitterness and contribute to its aroma, foam structure, and microbiological stability. Ultrasonic extraction…
