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.
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.
Steam distillation is a means of purifying fatty acids, e.g. from tall oils. [9] Steam distillation is sometimes used in the chemical laboratory. Illustrative is a classic preparation of bromobiphenyl where steam distillation is used to first remove the excess benzene and subsequently to purifiy the brominated product. [10]
Essential oils are usually extracted by distillation. Maceration is also used as a means of extracting essential oils. [5] In this process, used, for example, to extract the onion, garlic, wintergreen and bitter almond essential oil, the plant material is macerated in warm water to release the volatile compounds in the plant.
Steam distillation, which produces an essential oil called rose otto or attar of roses. Solvent extraction, which results in an absolute called rose absolute. Supercritical carbon dioxide extraction, yielding a concrete that may be marketed as a concrete, absolute or CO 2 extract.
Maceration, as used to soften and degrade material without heat, normally using oils, such as for peppermint extract and wine making. Distillation or separation process, creating a higher concentration of the extract by heating material to a specific boiling point, then collecting this and condensing the extract, leaving the unwanted material ...
Attar, also known as ittar, is an essential oil derived from botanical or other natural sources. Most commonly these oils are extracted via hydrodistillation or steam distillation. The Persian physician Ibn Sina was the first to derive the attar of flowers from distillation. [1]
SFE can be used as a sample preparation step for analytical purposes, or on a larger scale to either strip unwanted material from a product (e.g. decaffeination) or collect a desired product (e.g. essential oils). These essential oils can include limonene and other straight solvents. Carbon dioxide (CO 2) is the most used supercritical fluid ...
