title: Differentiation of the geographical origin of durum wheat semolina samples on the basis of isotopic composition.
abstract: The identification of the geographical origin of foods is attracting great interest from consumers and producers since it may be used as a criterion for guaranteeing quality and authenticity. Stable isotope techniques can provide useful information on the origin of food products. The natural abundance isotopic ratios of carbon, oxygen and nitrogen were determined and a comparison made between the isotopic content of samples originating from Italy and those of samples originating from other countries (Canada, Turkey, Australia). A correlation was found between the isotopic composition and geographical origin of the samples. The relationship between isotopic content and the latitude has been confirmed.
