[Eventual presence of 3-4 benzopyrene in the non-saponificable part of sunflower oil].

Within the limit of the research on the chemical composition of the nonsaponds of the edible oils, under execution in our Institute have been affected some cromatografic gas and spectoskopic analysis (U.V.) on a sample of sunflower seeds oil. Concentrating our research essentially on the determination of the presence of 3-4 benzopyrene in the above oil, we have treated about 8,3 gr. of nonsapond with appropriate chemical methodologies, in order to obtain specific samples for the polycyclic aromatic hydrocarbon analysis. The results of the cromatografic gas and spectoskopic of two fractions, obtained through the process of the preparation of the nonsapond sample, compared with those of a standard solution of 3-4 benzopyrene, exclude the presence of the hydrocarbon in the sunflower oil.
