In general, food safety and traceability through out the whole food produetion chain are in focus and research in this field will have high priority in Norway and in the European Union in ihe future (eg the EU document White Paper on Food safety". Nationa l and international regulations existing today include, to a large extent, only metbods intended to be used for produet identification, which are only valuable for general quality control. It is a need for metbods that can be used to determine authenticit y of produets in the immediate future. In this co-operation projeet with the university of Nantes (France), industry in Norway and SINTEF/NTNU we want to optimize the use ofNMR techniques for detection of origin and adulteration of foodstull. The projeet will be a continuation of NER projeet "Studies of fish and fish produet origin through the use of NIVIR (nuclear magnetic resonance) and mass spectrometry". We have shownthat NMR speetra are unique "fingerprints". However, we have to optimize the use of the NMR technique as a tool in origintesting and detection of adulteration through the application of various multivariate analysis methods for processing NMR data. Furthermore, 1H, 2H and 13 C NMR studies will be carried out on de pot fat from fish (wil d and farmed), edible oil/marine oil as an ingredient for food and feed. These reference samples will be the basis for a data base that will be built up during the projeet that will be available for the industry. A PhD study will be ineluded in tbe projee t. The student have to stay for a period at the University of Nantes, France performing NMR experiments.
