Cumin seed scfe co2 oil contain monoterpene aldehyds cuminaldehyde, p-mentha-1,3-diene-7-al and p-mentha-1,4-diene-7-al and the terpene hydrocarbons gamma terpinene, beta pinene and cymene. The oil is extracted from the seed which dried before extraction. With supercritical fluid extraction with natural carbon dioxide there are no solvent residues, no inorganic salts, no heavy metals and no reproducible microorganisms. It is widely used in products like cheese, sausages, soups, stew, in fillings and in liqueurs. It is used in medicines as carminative for stomach trouble and colics. It has anti-inflammatory and antimicrobial properties and because of it is used in natural remedies and in cosmetics.

It is widely grown in Mediterranean regions, Middle East countries, Eastern Europe and West Asia. It has been used traditionally used for centuries to treat asthma, cough, headache, rheumatism, fever, eczema and influenza especially in countries like India, Middle East and North Africa. Supercritical fluid extraction has many benefits. Compared to the conventional methods it is environmentally compatible fluids, has low temperature, the extraction time is shorter and it is easy for the separation of solute from supercritical fluid solvent by simple expansion. SCFE extraction will not leave any trace of organic solvent and the most frequently employed solvent is carbon dioxide (CO2). It has less toxicity, and it is safe and cheap and has low critical temperature and pressure.
Cumin seed oil is used largely for medicinal purposes and food flavoring. It is an antiseptic, anti toxic, anti-oxidant, antispasmodic, digestive, larvicidal, emmenagouge, diuretic, nervine and a stimulant. It is used as a warming oil to ease off the muscular pain and osteoarthritis. It is useful for the digestive system and helps with colic, dyspepsia, flatulence, bloating and indigestion.
