Ultrasonic extraction or sono-extraction is a process intensifying technology, which works by the coupling of high power ultrasonics into a slurry of plant or cell tissue. Hielscher Ultrasonics supplies reliable ultrasonicators for cell disruption and extraction from small lab samples up to high volumes in industrial processing. The appeal of the ultrasonically assisted extraction lies in the non-thermal treatment of the material, its easy application and the scaleability from test to production scale. Hielscher’s ultrasonic devices generate high intense ultrasound that can be exactely controlled to your process requirements.
Process intensification makes the reactions and the production of materials more efficient. Ultrasonic processing is well known to speed-up processes and to improve the output (e.g. superior quality, higher yields).

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.

Ultrasonication intensifies conventional solvent extraction and makes the process significantly more efficient. Ultrasonic extraction works with various types of solvents such as water, ethanol, methanol, isopropanol, vegetable oils, glycerin to name just a few. Ultrasonically generated cavitation improves mass transfer and disrupts cells so that the intracellular material and the targeted bioactive substances are released into the solvent. As a non-thermal extraction method, sonication prevents the thermal degradation of thermo-labil ingredients. Thereby, ultrasonic extraction increases the yield, improves extract quality and speeds-up the process.

The application of powerful ultrasound waves to liquid food products is used to homogenise and disperse them evenly, to extract aromatic and bioactive compounds (e.g. flavours, vitamins, natural colorants) and to improve microbial stability. As a non-thermal treatment, ultrasonication avoids the thermal decomposition of temperature-sensitive substances and is thereby a mild processing method. Hielscher Ultrasonics offers a wide product range of high-performance ultrasonic food processing systems, which can be operated in batch mode or continuous inline setup using an ultrasonic flow-through reactor.

Ultrasonic extractors are the superior tool when it comes to the intensification of ultrasonic extraction processes. As a non-thermal method, sonication prevents the degradation of temperature-sensitive substances (e.g. vitamins, flavours, antioxidants, CBD etc.). The application of high-power ultrasound waves causes the perforation and disruption of cells and tissues and promotes mass transfer. This means the intracellular material (i.e. the targeted substances) is released from the inner cell and transferred into the solvent. Ultrasonic extraction intensifies the extraction process resulting in higher yields, superior extract quality and rapid processing. At the same time, ultrasonic extraction is an environmental-friendly, green method.

Ultrasonication is the application of intense ultrasound waves into liquids and slurries. The 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 forces agitate particles, break droplets and disrupt cells causing homogenisation, dispersion, emulsification and extraction effects.

Sonochemistry is the application of ultrasound to chemical reactions and processes. SOnication is used to intensify chemical reactions such as synthesis and catalysis. When intense ultrasound waves are couples into liquids, the phenomenon of acoustic cavitation occurs. Ultrasonic cavitation improves mass transfer between reactants, speeds up the reaction and/or allows to change the chemicals pathway.

Ultrasonic devices couple intense ultrasound waves into liquids and slurries in order to homogenize, disperse, emulsify, extractor to initiate chemical reactions. The vibration of low-frequency, high intensity ultrasound is transmitted via a sonotrode (also known as ultrasonic probe, horn, or tip) into the medium so that acoustic cavitation occurs. In the energy-dense cavitation field high pressure and temperature differentials, high shear forces and turbulences are the responsible forces, which promote homogenisation, particle fragmentation, the breakage of droplets, cell disruption and mass transfer.

Ultrasonic dispersers are a common tool used to distribute particles of one phase (dispersed phase) in a continuous phase of a different material assisted by ultrasonic waves. Due to the intense dispersion forces of high-performance ultrasound, sonication is the superior method for the preparation of nanoparticle suspensions (e.g. CNTs in an aqueous medium). The energy input and intensity of sonication can be precisely controlled. Due to the exact control of the ultrasonic process parameters, sonication results are reproducible and can be linearly scaled to larger volumes. Ultrasonic dispersion achieves narrow particle distribution curves and the high quality dispersions.

Lysis is the term which describes the disruption of cell walls or membranes. Ultrasonic disruptors are a reliable tool to break cells in order to release intracellular compounds such as DNA, proteins, organelles, and phytochemicals. For ultrasonic lysis (aka cell disruption), high-intensity / low-frequency ultrasound waves are applied to disrupt the cell membranes. Since ultrasonication promotes mass transfer, the intracellular material is released into the surrounding solvent. The fluid containing the contents of lysed cells is called a lysate.
Cell lysis is the first step in cell fractionation, organelle isolation and protein extraction and purification.
