“…The levels of these minor bioactive constituents are variable in EVOO. These variations have been attributed to different factors, including agronomic and technological practices, cultivar, ripening stage, climate conditions and geographic origin (Servili et al, 2009;Laincer et al, 2016). Nevertheless, factors influencing the CoQ 10 content of olive oils have been scarcely investigated (Žmitek et al, 2014).…”

A B S T R A C TThere is currently an emerging production of olive oil in Brazil but it is still poorly characterized. In this study, we performed a comparative analysis of minor bioactive constituents (CoQ 10, tocopherols and phenolic compounds) in extra virgin olive oil from different regions of Brazil and Spain, of Arbequina cultivar. Significant variations (P < 0.05) in the concentration of the compounds analyzed were observed among oils from the different growing areas, not only between Spanish and Brazilian samples but also within zones of the same country. All the oils analyzed showed a high content of CoQ 10 , which ranged from 48 to 85 mg/L. The α − tocopherol was the major isomer quantified and three main groups of phenolic compounds were identified: flavonoids (apigenin, luteolin), phenolic acids (naringenin, p-coumaric acid, vanillic acid) and phenolic alcohols (hydroxytyrosol). Climatic and geographic factors of the production zones greatly influenced the minor fraction composition; positive relationships between altitude and the level of CoQ 10 , tocopherols and phenolic compounds of the oils were observed, whereas a negative correlation with rainfalls was found. Chemometric analyses demonstrated that oils were differentiated by the chemical composition and origin area and that polyphenols (particularly hydroxytyrosol) held the major weight in the oil classification.

“…These results are consistent with those found by Douzane et al () for the α‐tocopherol content of two Chemlal samples (≈189.86 and 180.02 mg kg −1 ). Laincer et al () have determined the α‐tocopherol content of oils from 19 Algerian VOO varieties. Contents found for one sample from four varieties ( Aberkane [220.2 mg kg −1 ], Aimel [252.2 mg kg −1 ], Bouchouk Gergour [233.9 mg kg −1 ], and Bouichret [207.5 mg kg −1 ]) are into the variation range of results reported in Table .…”

“…Only few data on the chemical composition of the Algerian olive oils are available and they are often incomplete or false. Some studies provide quality indices, fatty acid compositions, phenolic compounds, and tocopherols for the varieties Aghenfas , Azeradj , Bouichret , Chemlal , Grosse Hamma , Limli , Sigoise , Tahesrit , and for four oleaster populations (Bakhouche, Lozano‐Sánchez, Bengana, Fernández‐Gutiérrez, & Segura‐Carretero, ; Bouarroudj, Tamendjari, & Larbat, ; Douzane et al, ; Laincer et al, ; Louadj & Giuffre, ; Moussaoui, Labbaci, Hemar, Youyou, & Amir, ). Pigments (chlorophylls and carotenoids) were determined in three varieties: Chemlal , Sigoise , and Tabelout (Zegane, Keciri, & Louaileche, ).…”

Differences in triacylglycerol, fatty acid, squalene, and tocopherol compositions were demonstrated between 8 varieties of virgin olive oils (Aberkane, Aguenaou, Aharoun, Aimel, Bouchouk Guergour, Bouichret, Chemlal, and Sigoise) from Petite Kabylie area, north eastern Algeria. Fatty acid and triacylglycerol morphotypes characterized each variety. A principal component analysis, based on triacylglycerol, fatty acid, and squalene compositions, differentiates between varieties. Minor fatty acids and squalene, usually not taken into account individually in authentication studies, are strongly involved in this differentiation, whereas the discriminant power of tocopherols is weak. Soft Independent Modeling of Class Analogy classification using chemical compositions as variables showed a high potential to authenticate the varietal origin of Algerian virgin olive oils.

“…In recent years many studies have been performed to characterize and classify according to the geographical origin olive oils using different “unconventional” techniques, such as Isotope Ratio Mass Spectrometry (IRMS) [ 7 , 8 , 9 ] and Nuclear Magnetic Resonance (NMR) [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ] or their combination [ 19 ].…”

An analytical approach including Panel Test, Isotope Ratio Mass Spectrometry (IRMS) and Nuclear Magnetic Resonance (NMR) spectroscopy was proposed to characterize Italian “Colline Pontine” PDO olive oils (40 samples) of two consecutive crop years. Our approach has evidenced the high quality of these olive oils. Only 6 of 40 olive oils samples were defined as “defective” by the official Panel Test due to the detection of negative sensory attributes. The low variability of isotopic data monitored by IRMS confirmed that the olive oil samples all came from a limited geographical area. NMR spectra did not evidence any chemical composition anomaly in the investigated samples. In order to assess the influence of harvesting year over the olive oil chemical composition, the NMR analysis was extended to other 22 olive oil samples of a third harvesting year. NMR data were submitted to two different statistical methods, namely, analysis of variance (ANOVA) and principal component analysis (PCA) allowing olive oils of three consecutive harvesting years to be grouped.
