CORIANDER OIL

Химические свойства

Coriander oil is obtained by steam distillation of ripe fruits of Coriandrum sativum L. (Apiaceae). It is an almost colorless to pale yellow liquid with a characteristic odor, reminiscent of linalool.
d²⁰₂₀ 0.862–0.878; n²⁰_D 1.4620–1.4700; α²⁰_D +7 ° to +13 °; acid number: max. 3.0; content of linalool by GC: 65–78% .
The main component of coriander oil is (3S)-(+)-linalool (“coriandrol”). Mono- and polyunsaturated fatty aldehydes, although minor components, contribute to the characteristic aroma of the oil because of their powerful odor. In contrast to the seed oil, coriander leaf oil contains these aldehydes as main constituents, for example, 2-decenal and 2-dodecenal.
Coriander is mainly cultivated in Eastern Europe (Russia, Ukraine, Hungary), India, and Egypt. In the Soviet era, Russian Coriander oil was produced in large amounts (600 t/yr) for the isolation of linalool as raw material for the domestic fragrance industry. Today, coriander seed and leaf oils are produced on a much smaller scale of some 10 t and are used for flavoring seasoning mixtures and in perfume compositions.
