| Description | A tree, 9 to 15 m (30 to 50 ft.) tall, having a rounded and conicalhead, ovate glabrous leaves, and smooth, gray-brown bark. Theflowers are large, white, and fragrant. The fruits are large, lightlemonor orange with a thin rind and grayish-yellow or pink flesh.Historically and botanically, the origin of the grapefruit is uncertainand appears to have developed from the Shaddok variety nativeto the West Indies. The plant is cultivated in the United States(Florida, California, Texas), East Asia, West Indies, Brazil, andNigeria. The Citrus decumana variety yields the largest fruits (upto 10 kg). The parts used are the fruit and peel. Grapefruit has afresh, citrus-like odor and a taste reminiscent of sweet and bitterorange to some degree. Grapefruit essential oil is the volatile oil obtained by cold expressionof the fresh peels of the fruit. The oil is a yellow, sometimesreddish liquid (often showing a flocculent separation of waxymaterial) with a pleasant citrus-like odor and flavor. Its main constituents include limonene (90%), 2 to 3% volatilefraction containing oxygen compounds and sesquiterpenes, 7 to8 % waxy fraction, C8 and C10 aldehydes, geraniol, cadinene, smallamounts of citral and dimethyl anthranilate, and acids. A terpenelessoil can be prepared by vacuum distillation, yielding a moresoluble and more stable concentrated oil. However, a certainamount of terpenes must be left in the oil to retain the characteristicfreshness of citrus flavor. A lower grade of essential oil that does not have application inflavor work is also obtained by steam distillation of the crushedpeels or even from seeds. The derivatives are juice and extract. Naringin, a bitter, white,crystalline glucoside, is found in the blossoms and the flavedo ofthe fruits. Naringin yields rhamnose and naringenin (C15H12O5) onhydrolysis. A naringin extract, prepared from the expressed peels,is used in flavors. |
| Chemical Properties | Grapefruit oil is the volatile component obtained by expression of the fresh peels of the fruit It has a pleasant citrus-like odor and favor A low-grade oil is obtained by steam distillation of the crushed peels or even from seeds, but is not used in favor work In the United States, grapefruit oil is produced mainly in Florida and to a lesser extent in Texas and California. |
| Chemical Properties | Grapefruit oil is obtained by cold-pressing of the outer peels of the fruits ofCitrus x paradisi Macfad. (Rutaceae). It is a greenish-yellow liquid, with anodor resembling that of sweet orange oil, but more herbaceous and bitter. d2020 0.852–0.860; n20D 1.4740–1.4790; α20D +91 ° to +96 °; total carbonylcontent calculated as decanal of 0.28–2%; evaporation residue: max. 10.0%. Usually, grapefruit oil contains more than 90% (+)-limonene (92–96%).Constituents determining the typical sensory properties are present only inlow concentrations, for example, octanal (0.2–0.8%), decanal (0.1–0.6%),and 0.01–0.8% nootkatone, which is primarily responsible for the characteristicaroma of grapefruit oil. The sensory properties varywith the grapefruit cultivar (e.g., white/pink grapefruits) used for the oil production. The main producer of the oil is still the United States (Florida), althoughthe grapefruit cultivation declined drastically after the hurricanes in2004/2005. Additional oil producers are Cuba, Israel, Argentina, Mexico,Southern Africa, and so on. Worldwide production was estimated at～2000 t/yr in 2001/2003. Grapefruit oil is used mainly for flavoring fruit beverages. As with bergamotoil, the use of cold-pressed grapefruit oil is restricted in perfume compositionsdue to a content of furocoumarins. |
| Physical properties | Its color is yellow, sometimes reddish (often showing a focculent separation of waxy material) It is soluble in most fxed oils, often with opalescence or cloudiness It is slightly soluble in propylene glycol and insoluble in glycerin It may contain. |
| Occurrence | Found in the fresh peel of the fruit Citrus paradisi Macfayden (Fam. Rutaceae). |
| Uses | grapefruit oil is used as a fragrance and also as an active component with anti-irritant properties. grapefruit oil is indicated for work with the lymphatic system. |
| Definition | Extractives and their physically modified derivatives. Citrus paradisi, Citrus. |
| Preparation | By expression of the fresh peel of the fruit. |
| Essential oil composition | The main constituent of grapefruit oil expressed is limonene |
