Oleoresins are semi-solid extracts composed of resin and essential or fatty oil, obtained by evaporation of the solvents used for their production. [1] The oleoresin of conifers is known as crude turpentine or gum turpentine , which consists of oil of turpentine and rosin .
The resinoids described above should be distinguished from prepared oleoresins (e.g., pepper, ginger, vanilla oleoresins), which are concentrates prepared from spices by solvent extraction. The solvent that is used depends on the spice; currently, these products are often obtained by extraction with supercritical carbon dioxide. Pepper and ...
In modern vegetable oil production, oils are usually extracted chemically, using a solvent such as hexane. Chemical extraction is cheaper and more efficient than mechanical extraction, at a large scale, leaving only 0.5–0.7% of the oil in the plant solids, as compared to 6–14% for mechanical extraction.

Zingerone is similar in chemical structure to other flavor chemicals such as vanillin and eugenol. It is used as a flavor additive in spice oils and in perfumery to introduce spicy aromas. Fresh ginger does not contain zingerone, but it is produced by cooking or drying of the ginger root, which causes a reverse aldol reaction on gingerol.
Paprika oleoresin (also known as paprika extract and oleoresin paprika) is an oil-soluble extract from the fruits of Capsicum annuum or Capsicum frutescens, and is primarily used as a colouring and/or flavouring in food products. It is composed of vegetable oil and capsanthin and capsorubin, the main colouring compounds (among other carotenoids ...
Linalool has multiple commercial applications, the majority of which are based on its pleasant scent (floral, with a touch of spiciness). [3] [4] A colorless oil, linalool is classified as an acyclic monoterpenoid. [1] In plants, it is a metabolite, a volatile oil component, an antimicrobial agent, and an aroma compound. [1]
Gingerol ([6]-gingerol) is a phenolic phytochemical compound found in fresh ginger that activates heat receptors on the tongue. [1] [2] It is normally found as a pungent yellow oil in the ginger rhizome, but can also form a low-melting crystalline solid.
Fragrance bottles. An aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor.For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose.
