Description

Ultrasonic homogenizers are powerful tools to mix and homogenize solid-liquid and liquid-liquid suspensions. Ultrasonic homogenization is a mechanical process to reduce particles in a liquid so that they become uniformly small and evenly distributed. RPS-SONIC offers powerful ultrasonic homogenizers for application in lab and production scale.

Cell Disintegration

Under intense sonication enzymes or proteins can be released from cells or subcellular organelles as a result of cell disintegration. In this case, the compound to be dissolved into a solvent is enclosed in an insoluble structure. In order to extract it, the cell membrane must be destructed. Cell disruption is a sensitive process, because the cell wall’s capability to withstand high osmotic pressure inside. Good control of the cell disruption is required, to avoid an unhindered release of all intracellular products including cell debris and nucleic acids, or product denaturation. Ultrasonication serves as a well-controllable means for cell disintegration. For this, the mechanical effects of ultrasound provide faster and more complete penetration of solvent into cellular materials and improve mass transfer. Ultrasound achieves greater penetration of a solvent into a plant tissue and improves the mass transfer. Ultrasonic waves generating cavitation disrupt cell walls and facilitate the release of matrix components.

Protein and Enzyme Extraction

In particular the extraction of enzymes and proteins stored in cells and subcellular particles is a unique and effective application of high-intensity ultrasound (Kim 1989), as the extraction of organic compounds contained within the body of plants and seeds by a solvent can be significantly improved. Therefore ultrasound has a potential benefit in the extraction and isolation of novel potentially bioactive components, e.g. from non-utilized by-product streams formed in current processes. Ultrasound can also help to intensify the effects of enzyme treatment, and by this reduce the amount of enzyme needed or increase the yield of extractable relevant compounds.

Extraction of High-Quality Extracts from Botanicals

For high-quality botanical extracts from not only the raw material (plant material) is essential, but also the extraction technique applied is crucial. Plant extracts are temperature-sensitive, which means they are degraded by heat. It is therefore crucial to choose a non-thermal extraction method.
The selection of the extraction solvent is another important factor, which influences the extract quality. Solvents such as hexane, methanol, butane and other harsh chemicals can contaminate the extract. Even though solvents are removed after extraction, trace amounts of toxic solvents can be found in the final extract. Water, alcohol, ethanol, glycerine or vegetable oils are safe, non-toxic solvents and approved by the FDA for consumption.

When compared to conventional homogenization methods, ultrasonic homogenizers excel with the following qualities:
Ultrasonic homogenizers produce small particles / droplets and a narrow distribution curve.
Ultrasonic homogenizers can handle high solid concentrations. Ultrasonic homogenizers prepare stable suspensions, dispersions and emulsions.
Ultrasonic homogenizers are precisely controllable as the important process parameters (e.g. amplitude, power, time, temperature and pressure) can be influenced and adjusted.
Ultrasonic homogenizers are very effective, energy-efficient, user-friendly and safe to operate.
