Fennel Oil Usage And Synthesis
- Chemical PropertiesFennel oil is obtained by steam distillation of the aerial parts of Foeniculum
vulgare Mill. ssp. vulgare var. vulgare (bitter fennel). It is a colorless to pale
yellow liquid with a camphoraceous, sweet–spicy odor and a slightly bittersweet
camphoraceous taste, d2020 0.944–0.973; n20D 1.514–1.538; α20D +11 ° to +29 °.
The main constituents are monoterpene hydrocarbons such as ??-phellandrene
(0–8.5%) and limonene (1–6%), fenchone (10–25%), estragole (1–6%), and
(E)-anethole (50–78%). With increasing maturity of the fruits, the content
of monoterpenes decreases. The ripe fruits yield an oil with 50–70% anethole and
5–25% fenchone. In contrast, the oil of the ripe fruits of sweet fennel (F. vulgare
Mill. ssp. vulgare var. dulce) contains less than 5% fenchone and more than 75% anethole.
Fennel oil is produced mainly in Hungary, Tasmania, North Africa, and India in a quantity of few 10 t/yr. In total. It is used in flavoring oral care products and alcoholic beverages (anise liqueurs).
- Chemical PropertiesThe oil is obtained by steam distillation of the seeds Fennel sweet oil has a characteristic anise odor.
- Chemical PropertiesThe oil is obtained by steam distillation of the dried, comminuted seeds in varying yields, usually from 2 5 to 6 5%, depending on the plant origin It has an aromatic, spicy odor and an initially slightly bitter, camphoraceous, then sweet, favor.
- Physical propertiesIt is a colorless to pale-yellow liquid.
- Physical propertiesIt is a yellowish-green liquid.
- OccurrenceFound in the plant Foeniculum vulgare Thellung (Fam. Umbelliferae) (Guenther, 1950).
- UsesFlavoring agent in foods and pharmaceuticals. Fennel Oil can be used in eye washes and in facial steams to soothe and clean skin.
- PreparationBy steam distillation of the seeds of Foeniculum vulgare (Fenarolfs Handbook of Flavor Ingredients, 1971).
- Essential oil compositionThe main constituents of the oil include anethole, d-phellandrene and d-limonene.
- Essential oil compositionThe oil contains up to 90% trans-anethole and up to 20% fenchone and small amounts of limonene, α-pinene, camphor and additional volatile compounds.
- Safety ProfileModerately toxic by ingestion. Mutation data reported. A severe skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
