Abstract
AbstractIn a 3‐year study, the chemical compositions of extra virgin olive oils (EVOO) of Bosana variety deriving from three different growing areas in Northern Sardinia were characterized, together with the pedo‐climatic conditions of the three different growing areas, to gauge any differences at the chemical level. The main chemical differences in the oils from the three‐studied areas were recorded in the fatty acid profiles [palmitic, oleic, and linoleic acid; sum of saturated (SFA), monounsaturated (MUFA), and polyunsaturated (PUFA) fatty acids]: these dissimilarities were ascribable to the environmental characteristics of the Alghero area, while others analytical parameters such as tocopherols, pigments, phenolic, and volatile compounds were not affected by production area. Fatty acids profile revealed a clear relation with temperature at a mesoclimate level, allowing a clusterization of the production areas. Our study provided evidences that pedo‐climatic factors affect the quality of EVOO; in particular, in the case of Bosana cultivar the acidic fraction resulted one of the main traits differentiating the olive growing areas.
