The Effect of the Climatic and Topographic Conditions of Different Locations on the Geographical Fingerprints of EVOOS by using LC IMS Qtof Mass Spectrometry

Abstract

: The polyphenolic compounds and sterols present in six samples of olive fruits which obtained different climatic and topographic conditions in same region were analysed by LC IMS Qtof mass spectometry. All samples were collected same day during the normal picking period for olive oil production, in Karaburun region of Izmir provience and were obtained from the Erkence variety in six different olive location areas. In the Karaburun region samples, it was analyzed the obtained data using Progenesis QI software to analyze multivariate and to determine the geographical differences with help of statics on sterol and polyphenol profiles of olive oils. Results showed that Karaburun region is clustered significant quantitative differences of virgin olive oils (EVOOs) from different geographical locations. These results permit to use a successful distinction of EVOOs this research. It is recommended that olive oils to be labeled as geographical indication should be labeled on the basis of small local regions.
