flavor.
d2020 0.900–0.940; n20D 1.490–1.5150; α20D +1 ° to +9 °; solubility 1 vol inmax. 8 vol
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%).
