“…Tunisia is the second country after the European Union in the olive oil exportation. The variety Chemlali contributes to 80 of the Tunisia national olive oil production and covers a wide geographical area where a wide range of edapho-climatic conditions are prevailing 5 . The quality and the particularity of the olive oil depend on several factors among those the cultivar is the main one.…”

“…Two cultivars, Chemlali and Chetoui, are the most important from the economic point of view. There are other cultivars that are grown in restricted geographical locations and which have a limited diffusion, such as Neb Jmel . Virgin olive oil (VOO) is unique among other vegetable oils due to its high levels of mono‐unsaturated fatty acids (mainly oleic acid) and the presence of minor components, such as phenolic compounds among others.…”

“…Indeed, over the last years, the chemical composition of olive oil has been widely used to identify its geographical origin, fact which is actually not surprising, since many authors have demonstrated that the olive oil composition is widely affected by the pedoclimatic conditions of the geographical area in which was produced . Certainly, characterizing major and minor components of olive oil for geographical classification purposes has been satisfactorily carried out on samples coming from diverse olive oil producing countries, mainly Spain , Italy , Greece , Tunisia , etc. In all the mentioned studies, different approaches combining profiling or fingerprinting of olive oil samples with the appropriate chemometric tools have been tested for the geographical classification of the studied oils, as well as the identification of markers that could facilitate this discrimination.…”

The triacylglycerols composition of monovarietal Picholine Marocaine olive oils, produced in seven of the most productive areas in northern Morocco, has been established for the first time, starting a register of typicality and geographical identity of Moroccan olive oils. Two hundred seventy-nine olive samples were collected over two consecutive crop seasons (2011/2012 (n ¼ 140) and 2012/2013 (n ¼ 139)), the analysis of the triacylglycerol profiles of the obtained oils was performed using high performance liquid chromatography, the influence of the region of provenance was investigated, and chemometric data analysis (including principal components analysis, linear discriminant analysis, partial least squares-discriminant analysis, and soft independent modeling of class analogies) was used to differentiate the studied samples according to their geographical origin. Twenty-one triacylglycerols were characterized and the variability observed among the studied samples could be related to the production area. The combination of triacylglycerols composition with chemometrics provided a powerful tool to verify the geographical origin of north Moroccan olive oils.Practical applications: Moroccan legislations established Geographic Indication labels for adding value to typical products. However, the general procedure to control the geographical authenticity of these protected products remains based on the traceability of their production and there is a lack of appropriate and reliable tools for their geographical unambiguous authentication and control. In this work, geographical authentication models for classifying olive oil samples (based on triacylglycerols composition) have been developed and evaluated, achieving adequate classification and prediction rates for oils coming from the main north Moroccan olive growing areas. The results obtained herein, could represent a significant contribution to the control of the geographical authenticity of Moroccan olive oils.
