What is Black Pepper Oil?

Chemical properties

(Black) Pepper oil and (black) pepper oleoresin are obtained from the black pepper Piper nigrum L. (Piperaceae). Pepper oil is produced by steam distillation of whole or crushed fruits. The oil is an almost colorless to bluish-green liquid with a characteristic odor, reminiscent of pepper, but without the pungency of the spice.

The oil contains mainly mono- and sesquiterpene hydrocarbons such as sabinene, α- and β-pinene, limonene, 3-carene and caryophyllene being the main constituents. The particular composition varies with the origin.
Pepper oleoresin is produced by solvent extraction and, unlike the oil, contains the principal pungent compound, piperine [94-62-2], along with some essential oil.

Chemical properties

Obtained by steam distillation of dried, unripe fruit. The yield ranges between 1 and 2.6%. Pepper essential oil has a characteristic odor of pepper and a relatively mild taste.

Physical properties

It is an almost colorless to slightly greenish liquid. It is soluble in most fixed oils, mineral oil and propylene glycol. It is sparingly soluble in glycerin.

The Uses of Black Pepper Oil

The cosmetic application of black pepper oil is unclear, though it may be used on skin inflammations and superficial wounds. This oil is obtained from a small-grain black pepper shrub found primarily in the hilly parts of Jamaica.

The Uses of Black Pepper Oil

Pungently aromatic condiment in foods.
