80% ethanol; carbonyl value corresponding to a calculated content of 45–58% of cuminaldehyde.
Cumin oil is produced mainly in India and in smaller quantities in Egypt,
Morocco, and Iran. Annual production quantities may be ±10 t. It is used in
very small amounts in green aldehydic fragrance compositions and for flavoring
seasonings, pickles, meat sauces of oriental and Asian types.
In addition to somemonoterpene hydrocarbons, the main constituents that also
determine the sensory properties are cuminaldehyde (15–46%), p-1,3-menthadien-7-al (2.8–22%), and p-1,4-menthadien-7-al ( 1.5–16%).
Physikalische Eigenschaften
The oil is a yellow-amber liquid that tends to darken on aging. The oil is quite sensitive to daylight,
air, moisture and metals as well as alkali.
Occurrence
Found in the seeds of Cuminum cyminum L. (Fam. Umbelliferae).
synthetische
By steam distillation of the crushed dried fruit of Cuminum cyminum L.
Essential oil composition
The volatile oil is primarily composed of cuminaldehyde (up to 60%). Besides cuminaldehyde, it also
contains α- and β-pinene, p-cymene, β-phellandrene and cuminyl alcohol.
Sicherheitsprofil
Moderately toxic by
ingestion and skin contact. A skin irritant.
Mutation data reported. When heated todecomposition it emits acrid smoke and
irritating fumes.
