Coriander Seed Essential Oil
Coriander seed essential oil is the volatile oil steam distilled from the ripe dried fruit of Coriandrum sativum. Its profile is dominated by linalool, which typically makes up sixty five to eighty percent of the oil and gives the sweet, floral, faintly woody character that distinguishes the seed from the herb, supported by alpha-pinene, gamma-terpinene, camphor, geranyl acetate and limonene.
The oil bears almost no resemblance to the leaf material of the same plant. Coriander leaf, known as cilantro, owes its polarising soapy character to aliphatic aldehydes that are absent from the ripe seed, so the seed oil is a mild, sweet, broadly liked flavour where the leaf is divisive.
It is a colourless to pale yellow mobile liquid, lighter than water, practically insoluble in water and miscible with ethanol and vegetable oils. Linalool is an alcohol rather than a terpene hydrocarbon, which makes the oil more stable to oxidation than citrus oils, though it still darkens and loses top notes on prolonged exposure to air and light, so it is stored cool in filled containers. Aqueous systems take it as an emulsion or a spray dried encapsulate.
We source bulk Coriander Seed Essential Oil from top China manufacturers for our partners. The manufacturer is in Henan. A smaller requirement can ship in a combined container with other ingredients.

Common Markets Grades
The oil is traded chiefly by linalool content and by origin, with Russian, Eastern European, Indian and North African material differing in linalool level and in the balance of the minor terpene fraction. Buyers specify a linalool range because it drives both flavour strength and value, and the oil is also bought as a natural source of linalool for isolation.
Crude distilled oil is sold alongside redistilled and rectified grades produced by vacuum distillation to remove colour and heavy residues, and terpeneless grades in which the hydrocarbon fraction is stripped to concentrate the oxygenated compounds and improve solubility in dilute alcohol. Organic certified oil is available, as is coriander seed oleoresin and the separate fixed oil pressed from the seed, which is a fatty oil rather than an essential oil and is not interchangeable with it.
Applications
- Gin and botanical spirits, where coriander seed is the second most important botanical after juniper and the oil is used to standardise the distillate
- Meat processing, in sausage, salami, frankfurter and cured meat seasoning
- Bakery, in rye and speciality breads and in spiced biscuits
- Curry and masala seasoning blends, supplying the sweet background note of the ground spice in concentrated form
- Beverages, in vermouth, bitters, herbal liqueurs and flavoured waters
- Pickles, sauces and condiments, in mixed pickling spice profiles
- Confectionery and chewing gum, as a sweet aromatic modifier
- Digestive and carminative preparations, in traditional herbal and pharmaceutical flavouring
- Fine fragrance and personal care, where linalool-rich oils are used in floral accords
- Feedstock for the isolation of natural linalool as a single flavour and fragrance compound

Regulatory Status
In the United States, 21 CFR 182.20 lists coriander oil among the essential oils, oleoresins and natural extractives generally recognised as safe for their intended use in food, and it carries FEMA GRAS status as a flavouring substance. Products using it are labelled as natural flavour, and use in cosmetics and personal care falls under the separate cosmetic labelling rules, where linalool is one of the fragrance allergens that must be declared above set thresholds.
In the European Union coriander seed oil is a natural flavouring preparation under Regulation (EC) No 1334/2008 on flavourings, which frames its use and the maximum levels of certain biologically active principles in flavourings from botanical sources. No E number applies. The Joint FAO/WHO Expert Committee on Food Additives has evaluated linalool and related aliphatic and alicyclic alcohol flavouring agents and publishes specifications for them, and coriander appears in Codex standards covering spices and culinary herbs.
Manufacturing Process
Coriander is harvested when the fruit is fully ripe and dry, since immature seed carries a harsher profile and lower linalool. The seed is threshed, cleaned of stalk and dust, and stored dry. Before distillation it is crushed or coarsely milled to open the fruit wall, because the oil is held in vittae inside the pericarp and intact seed distils slowly and incompletely.
Milled seed is charged into a stainless steel still and extracted by steam distillation over several hours, with the vapour condensed and the oil separated from the aqueous phase in a Florentine flask. The distillation water is normally cohobated to recover the dissolved linalool fraction. Crude oil is decanted, dried over a desiccant, and filtered. Rectification under vacuum follows where a colourless, low-residue grade is wanted, and fractional distillation is used for terpeneless material. The finished oil is profiled by gas chromatography, blended to a standard linalool specification and filled into lined drums under nitrogen.
