    A traditional Chinese herbal decoction (湯劑/汤剂) Turkish coffee beginning to boil. Decoction compares to brewing coffee through percolation.. Decoction is a method of extraction by boiling herbal or plant material (which may include stems, roots, bark and rhizomes) to dissolve the chemicals of the material.

  3. Phytoextraction process - Wikipedia

    en.wikipedia.org/wiki/Phytoextraction_process

    The plant roots must absorb the heavy metal. The plant must chelate the metal to both protect itself and make the metal more mobile (this can also happen before the metal is absorbed). Chelation is a process by which a metal is surrounded and chemically bonded to an organic compound. The plant moves the chelated metal to a place to safely store it.

  4. Fragrance extraction - Wikipedia

    en.wikipedia.org/wiki/Fragrance_extraction

    Fragrance extraction refers to the separation process of aromatic compounds from raw materials, using methods such as distillation, solvent extraction, expression, sieving, or enfleurage. [1] The results of the extracts are either essential oils , absolutes , concretes , or butters , depending on the amount of waxes in the extracted product.

  5. Leaching (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Leaching_(chemistry)

    Specific extraction methods depend on the soluble characteristics relative to the sorbent material such as concentration, distribution, nature, and size. [1] Leaching can occur naturally seen from plant substances (inorganic and organic), [2] [3] solute leaching in soil, [4] and in the decomposition of organic materials. [5]

    Most natural essences are obtained by extracting the essential oil from the feedstock, such as blossoms, fruit, and roots, or from intact plants through multiple techniques and methods: Expression ( juicing , pressing ) involves physical extraction material from feedstock, used when the oil is plentiful and easily obtained from materials such ...

  7. Enfleurage - Wikipedia

    en.wikipedia.org/wiki/Enfleurage

    The enfleurage fragrance extraction method is one of the oldest. It is also highly inefficient and costly but was the sole method of extracting the fragrant compounds in delicate flowers such as jasmine and tuberose, which would be destroyed or denatured by the high temperatures required by methods of fragrance extraction such as steam distillation.

  8. Infusion - Wikipedia

    en.wikipedia.org/wiki/Infusion

    Infusion is the process of extracting chemical compounds or flavors from plant material in a solvent such as water, oil or alcohol, by allowing the material to remain suspended in the solvent over time (a process often called steeping). An infusion is also the name for the resultant liquid.

  9. Sonication - Wikipedia

    en.wikipedia.org/wiki/Sonication

    Sonication can be used for the production of nanoparticles, such as nanoemulsions, [5] nanocrystals, liposomes and wax emulsions, as well as for wastewater purification, degassing, extraction of seaweed polysaccharides [1] and plant oil, extraction of anthocyanins and antioxidants, [6] production of biofuels, crude oil desulphurization, cell disruption, polymer and epoxy processing, adhesive ...
