Utrasonic topic: "What are Ultrasonic Extractors Used for?"
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.

Utrasonic topic: "extracts"
Extracts are substances, which have been released from a raw material via an extraction process. Ultrasonic extraction (also sono-extraction) is a highly efficient, rapid, safe, and user-friendly technique to extract bioactive compounds from botanicals such as herbs, seeds, fruits, vegetables, flowers, roots and bark. For the extraction process a solvent is required. One advantage of ultrasonic extraction is the broad selection of solvents to chose from: Ultrasonic extraction works with common solvents (e.g. ethanol, methanol, heptane, hexane etc.), but also very mild, green solvents such as water, vegetable oils, glycerine etc. are suitable for the ultrasonic extraction from many raw materials.
Extracts are available as tinctures, absolutes or in powder form. Extracts are often used in the food, pharma and nutraceutical industry, where extracts are used as flavour additives or as bioactive compounds with medicinal or nutritional effects.
Utrasonic topic: "terpenes"
Terpenes are a large and diverse class of organic compounds, produced by a variety of plants, particularly conifers, and by some insects. Terpenes exhibit unique flavours, aroma, and smells, but they have many other specific characteristics, which make them a valuable substance used in food, cosmetics, pharmaceuticals as well as in biotechnology or as natural agricultural pesticides. Most terpenes exhibit antimicrobial properties, which enable them to combat potentially harmful bacteria and viruses. Many terpenes, e.g. beta-caryophyllene, are also known as anti-inflammatory and pain relieving, which makes them an analgesic alternative.
Ultrasonic extraction is the preferred technique to release terpenes from the cell matrix of botanicals (e.g. cannabis, hops, neem, menthol etc.). Ultrasonic extraction is based on the principle of acoustic cavitation, which breaks the plant cell and increase the mass transfer between the cell interior and the surrounding solvent. The main advantages of ultrasonic extraction are a more complete extraction, and the rapid, mild, non-thermal process.
The Large Variety of Terpenes
Currently, there are more than 20,000 identified terpenes .
Very prominent and well known terpenes are caryophyllene, limonene, pinene, linalool, humulene, and myrcene.
Caryophyllene is a sesquiterpene that is widely present in many essential oils, especially the essential oil of Cannabis sativa, clove, rosemary, and hops. It is responsible for the spicy or peppery aroma and is mostly used for its digestive, analgesic and antibacterial effects.
Humulene is a terpene found in hops, cloves, and basil, which used for its anti-inflammatory and antibacterial effects.
Limonene is a cyclic monoterpene, and the major component in the oil of citrus fruit peels. It is widely used as fragrance ingredient, dietary supplement and solvent in cleaning agents.
Pinene, found e.g. in the resins of many other conifers, is used as compound for perfumery as well as in the chemical industry.
Linalool, found e.g. in mint, laurel, birch trees, is a widely used fragrance and scent ingredient.
Myrcene is a monoterpene, which can be found e.g. in cannabis and hops. Due to its pleasant odor, it is an important intermediate used in the perfumery industry.
Utrasonic topic: "synthesis"
Chemical synthesis is a chemical reaction with the aim of converting one or more reactants into one or multiple products.
Intense ultrasound waves can be applied to improve chemical reactions (i.e. synthesis and catalysis) – a field known as sonochemistry. The effect of ultrasound on chemical reactions are based on the generation of acoustic cavitation in liquids. Sonication introduces energy into the chemical mixture, produces locally extreme conditions due to cavitation and promotes mass transfer. Thereby, it can greatly enhance chemical reactions such as synthesis (sono-synthesis) and catalysis (sono-catalysis). Ultrasonic energy can induce and accelerate reactions, increase the conversion rate as well as establish alternative synthetic pathways. As a result of that, ultrasound can make synthesis reactions more efficient, faster and environmental-friendlier.
Ultrasonically-assisted synthesis reactions such as the sono-synthesis of hydroxyapatite, silver nanoparticles, Mn3O4nanoparticles and a large variety of core-shell particles have been extensively studied and successfully scaled to industrial sized production.
Utrasonic topic: "lysis"
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.

Utrasonic topic: "antioxidants"
Antioxidants are naturally occuring compounds that inhibit oxidation. During oxidation free radicals are produced, which may damage cells and thereby negatively influence health and vitality.
Antioxidants act as free-radical scavengers. This means they can prevent or slow damage to cells caused by free radicals, unstable molecules that the body produces as a reaction to environmental and other stressors.
Main source of antioxidants are plants. Herbs, fruits and vegetables are rich in antioxidants and are therfore used as raw material to extract antioxidants. Plant nutrients and phyto-chemicals like vitamin A, C and E, the minerals copper, zinc and selenium, flavonoids, phenols, polyphenols, and phytoestrogens are known potent antioxidants.
Ultrasonic extraction is used to isolate antioxidative phyto-chemicals from botanicals in order to manufacture antioxidants, which are used in health foods, pharmaceuticals, supplements and as cosmetic additives. Being a non-thermal method, ultrasonic extraction prevents the thermal degradation of temperature-sensitive antioxidants. Furthermore, sonication gives high antioxidant yields in a very rapid process. Read more about the extraction of antioxidants and other bioactive substances below!
Utrasonic topic: "polyphenols"
Polyphenols or polyhydroxyphenols are chemical compounds that occur in nature, but can be also synthesized chemically. As polyphenols act as antioxidants, they are known as health-beneficial bio-compound and the consumption of polyphenol-rich foods such as fruits, vegetables, cereals, tea and coffee is linked to a reduced risk of chronic diseases.
Fruits like berries, grapes, apples, pears, and cherries show a high polyphenol content containing up to 200–300mg polyphenols per 100 grams fresh weight. Subsequently, products manufactured from these fruits, also contain significant amounts of polyphenols.
The class of polyphenols includes tannins, catechins, epicatechins, flavanones, isoflavones, phloridzin, quercitin etc. In foods, polyphenols contribute to the bitterness, astringency, color, flavor, smell and oxidative stability. Therefore, polyphenol extracts, e.g. from grape skin, grape seeds, olive pulp, citrus peel, or maritime pine bark, are sold as ingredients for functional foods, dietary supplements, and cosmetics.
As secondary metabolites of plants, polyphenols are located within the cell matrix. In order to produce polyphenol-rich foods such as olive oil, wine, juices, purees or extracts, the polyphenols must be released from the plant cells. Ultrasonic extraction is a powerful method to break cell structures of botanicals and to release them into the surrounding liquid. As a non-thermal technique, ultrasonic extraction prevents the thermal decomposition of the heat-labil polyphenols. At the same time, sonication is a process-intensifying method, which increases the extraction yield and accelerates the process speed. Ultrasonic extraction is used to produce superior polyphenol extracts. Available from lab to industrial scale, ultrasonic processors can be easily implemented into your production line to improve your extraction process.

Utrasonic topic: "ultrasonicator"
Ultrasonicators are ultrasonic probe-type devices, which are used for manifold applications including homogenization, dispersing, wet-milling, emulsification, extraction, lysis, disintegration, and chemical reactions.
The working principle of an ultrasonicator is based on the phenomenon of acoustic cavitation. When intense ultrasound waves are coupled into a liquid, alternating high-pressure / low-pressure cycles travel through the liquid. During the low-pressure cycles, the ultrasonic waves create minuscule vacuum bubbles, which grow over several pressure cycles. When the vacuum bubbles reach a volume at which they cannot absorb further energy, they implode violently during a high-pressure cycle. Briefly, cavitation is the growth and collapse of vacuum bubbles or cavities. During the bubble implosion, an exceptionally energy-dense field is created. In an acoustic cavitation field, extreme conditions – including very high temperature and pressure differentials, turbulences, shear forces and liquid jets – can be measured. These intense cavitational forces are used to fulfil the manifold applications mentioned above.
Ultrasonicators create cavitation to apply it purposefully to liquids, slurries and gas in order to achieve particle size reduction, mixing of oil/water phases, cell disruption or to induce chemical reactions.
Sonication (also ultrasonication) describes the process of applying ultrasound energy to a liquid or slurry. Hielscher Ultrasonics designs, manufactures and distributes high-intensity, low-frequency ultrasonicators from lab & bench-top to fully industrial scale.
