Abstract
Gas liquid chromatography (GLC) was used for the detection of rapeseed oil added to olive oil, corn oil and cottonseed oil. The chroma­tograms of the unsaponifiable matter could be divided into two parts representing hydrocarbons and sterols. Squalene as hydrocarbon, brassi­casterol, campesterol and B-sitosterol as sterols , also the ratio of TH/Ts were used for the detection of adulteration of olive oil with rapeseed oil. in fatty acid analysis, oleic acid, linoleic acid and the ratio of OIL, also linoleic to total unsaturated ratios were used as a safe criterion for even­tual adulteration of corn oil and cottonseed oil with rapeseed oil.
