Edible oils and fats are complex mixtures of compounds. This article describes the role of normal-phase liquid chromatography as a generic sample pretreatment tool prior to detailed gas chromatography (GC) analysis.

Edible oils and fats are complex mixtures of compounds. To understand the properties of an oil or fat, information on groups of molecules, as well as individual molecules, is needed.

Multiple fractions can be tested in parallel with this fast method.

Many edible oils contain natural antioxidants that protect the oil from lipid oxidation, Knowledge on the identity of these oxidation inhibitors is crucial to find natural ways to protect healthy, unsaturated fats and oils from turning rancid. This article describes a new assay that allows rapid quantification of the lipid oxidation inhibting potenital of pure compounds or liquid chromatography (LC) fractions.
