Abstract
This review provides current information on the analytical methods used to identify food adulteration in the six most adulterated food categories: animal origin and seafood, oils and fats, beverages, spices and sweet foods (e.g. honey), grain-based food, and others (organic food and dietary supplements). The analytical techniques, both conventional and emerging, used to identify adulteration in these six food categories involve sensory, physicochemical, DNA-based, chromatographic, and spectroscopic methods, and have been combined with chemometrics, making these techniques more convenient and effective for the analysis of a broad variety of food products. Despite recent advances, a need remains for suitably sensitive and widely applicable methodologies that will encompass all the various aspects of food adulteration.
