Title: Minor polar compound and fatty acid analyses in monocultivar Croatian virgin olive oils

Abstract:
Virgin olive oil is a typical component of the Mediterranean diet, consumed unrefined and rich in important molecules, such as minor polar compounds (hydroxytyrosol, tyrosol, secoiridoids and flavonoids) and fatty acids. These molecules not only influence the sensorial properties of both olives and virgin olive oil but they are also important markers for characterization, biodiversity and quality determination of this product. The aim of this study was to evaluate the minor polar compound and fatty acid contents of 5 monocultivar virgin olive oils, typical of middle Dalmatia region, in order to have better knowledge about the quali-quantitative profiles of these compounds in samples obtained from both the same collecting season and same processing technique. Quali-quantitative analysis (performed by HPLC/DAD and GC) could be a useful tool to better correlate the typicity of the virgin olive oil with its minor polar compound and fatty acid pattern. The organoleptic assessment was also performed on the investigated olive oils in order to define their sensorial profiles. Further studies are in progress to isolate the specific compounds and to further investigate the quality index of this food product.
