Abstract This article reviews sample pretreatment techniques for heteroaromatic amines in cooked foods, introducing several analytical strategies for their extraction and preconcentration,such as liquid liquid extraction, column liquid chromatography,solid-phase extraction,on-line coupling of liquid liquid extrac-tion and solid-phase extraction.Then concentrates on the separation procedures,sorbents and solvents used in the sample treatment. Last discusses the requirements of the analytical techniques and the strategies most frequently followed to achieve accurate results.
