Chemical Properties

Different sources of media describe the Chemical Properties of 68916-04-1 differently. You can refer to the following data:
1. Bitter orange peel oil can be obtained by the following methods: (1) expression of fresh fruit rinds (peel) using suitable machinery that ruptures the oil-bearing cells, followed by separation and purification by centrifugation or (2) steam distillation of peels. The quality of the product obtained by expression is quite different and considered of much higher quality than oil obtained by steam distillation. The oil has a fragrant, bitter flavor.
2. Neroli bigarade is a product obtained by processing flowers of the bitter orange tree. The blossoming flowers are the only part used. Neroli bigarade has a very powerful floral odor with a bitter flavor. For additional information, see Orange, Bitter.
3. Bitter orange oil is obtained by pressing fresh peel fromthe fruits of C. aurantium L. (Rutaceae). It is produced mainly in Mediterranean countries and is a pale yellow to yellowish-brown liquid with a slightly mandarin-like odor and a somewhat bitter aroma. d2020 0.840–0.860; n20D 1.472–1.476; α20D +88 ° to +98 °; evaporation residue: 3.5–6%; solubility: 1 vol in ≤8 vol. 90% ethanol. Composition by GC: limonene 93–95%; linalyl acetate 0.5–1%; decanal tr. ?0.3% (data of Mediterranean type; data for American and Equatorial type may differ slightly). Although limonene is also the main component, at 92.95–95%, the content of other constituents differs from that of sweet orange oil; that is, its aldehyde content is lower and its ester (e.g., linalyl and geranyl acetate) content is higher. In addition to the fruits, other parts of bitter orange tree, C. aurantium L., also serve for the production of fragrant raw materials: Neroli oil and orange flower absolute are obtained from the flowers, and the twigs and leaves yield the so-called petitgrain bigarade oil. Worldwide production of bitter orange oil ismuch lower than that of other pressed peel oils. The preferred quality is produced in Spain (Seville bitter orange oil). Bitter orange oil is predominantly used for flavoring alcoholic beverages (liqueurs).

Physical properties

Different sources of media describe the Physical properties of 68916-04-1 differently. You can refer to the following data:
1. Oil obtained by expression has a deep-yellow color.
2. The absolute obtained from concrete is a yellow-red liquid with an extremely suave odor typical of the flower

Occurrence

Found in the fresh peel of the fruit Citrus aurantium Linne (Fam. Rutaceae).

Preparation

By the expression of the fresh peel of the fruit, Citrus aurantium Linne, by various methods, without the use of heat.

Essential oil composition

Different sources of media describe the Essential oil composition of 68916-04-1 differently. You can refer to the following data:
1. Dried flowers and leaves of bitter orange had a similar flavonoid pattern, but the flavonoid levels of flowers were higher than those of leaves. The mean levels of the principal flavonoid compounds were, respectively, total flavonoids 12.35 and 1.06%, neohesperidin 5.44 and 0.08%, naringin 1.93 and 0.06%, eriocitrin 0.38 and 0.25%.
2. The main constituents include d-limonene, various acids, aldehydes and diesters.
