Ultrasonic extraction results in a broad spectrum extract, containing nicotine, which is tobacco's primary alkaloid with 94- 98% of the total alkaloid content, as well as the alkaloids nornicotine, anabasine, anatabine, cotinine and myosmine.
Due to its high process efficiency, ultrasonic extraction allows to use a very broad range of raw materials to isolate antioxidants.
The authors of the study found that ultrasonic extraction in order to obtain the alcoholic extracts is one of the best techniques to replace the conventional techniques.
To produce high-quality capsaicin as aromatic flavour and medicinal ingredient, an efficient, yet mild extraction technique is required to prevent degradation. Ultrasonic extraction is….
For ultrasonic extraction, peripheral parameters such as raw material particle size, solvent type, solid-to-solvent ratio, and extraction time can be easily varied and optimized for best results.
As noted in Sec. 1.4, ultrasonic extraction may not be as rigorous a method as other extraction methods for soils/solids.
The ultrasonic extraction can be easily combined with pressure, heat, supercritical extraction conditions or Soxhlet extractor to improve results and/or adapt the extraction setup to specific requirements.
The principle of ultrasonic extraction is based on two effects, which are produced when high-power ultrasound waves are couples into a liquid or slurry.
The intense ultrasonic extraction process releases the remaining photo-compounds from the spent hops and helps to deplete the spent hops from all valuable substances so that no bioactive substances are wasted.
Hielscher's industrial-scale automated ultrasonic extraction systems are designed for high production capacities of superior quality extracts, whilst at the same time reducing labor, cost, and energy.
After the final ultrasonic extraction, pour the entire sample into the Buchner funnel, rinse the beaker with extraction solvent, and add the rinse to the funnel.
With thousands of installed ultrasonic extraction machines worldwide, Hielscher is not only your trustworthy partner for the hardware but also for consultation and project development.
After ultrasonic extraction, the targeted compounds are in the solvent and can be separated from the solvent(e.g. by evaporating the solvent) so that finally a pure extract is obtained.
Batch: Ultrasonic extraction processes can be operated as simple batch processes or as inline treatment, where the medium is continuously fed through an ultrasonic flow-through reactor.
The main advantage s of ultrasonic extraction are its exceptional high extraction rate, rapid extraction speed, the use of green solvents(e.g. water, ethanol, vegetable oils etc.), safety, and user-friendliness.
In a small scale beaker setup, maximum yield of piperine(5.8 mg/g) from ground Piper longum is obtained at optimized ultrasonic extraction conditions, which have been found to be the following.
Other studies demonstrate the successful ultrasonic extraction of anthocyanins from blueberries, blackberries, grapes, cherries, strawberries, and purple sweet potato amongst others.
Ultrasonic extraction can be run using various solvents such as water, citric acid, nitric acid solution(HNO3, pH 2.0), or ammonium oxalate/oxalic acid, which makes it also possible to integrate sonication into existing extraction lines(retro-fitting).
Astaxanthin is a highly potent antioxidant used in pharmaceuticals and nutritional supplements. In order to produce high-quality astaxanthin from natural sources such as algae, a high-performance extraction technique is required. Ultrasonic extraction is a mechanical treatment, which gives high….
