Analysis of single-cultivar extra virgin olive oils by means of an Electronic Nose and HS-SPME/GC/MS methods

Monovarietal extra-virgin olive oil classification: a fusion of human sensory attributes and an electronic tongue

“…Indeed, electronic noses (E-noses) and electronic tongues (E-tongues), individually or combined, have been proposed in the last decade for olive oil characterization using different multivariate statistical techniques. For instance, an E-nose has been successfully used for the discrimination of different Mediterranean single-cultivar EVOO [49]. More recently, our research team has shown that an E-tongue could be applied to successfully discriminate Portuguese (100 % of correct classification) or Spanish (97.5-100 % of correct classifications) monovarietal EVOO according to the olive cultivar, depending on the number of olive cultivars evaluated (3 or 11) [3,20].…”

Application of an electronic tongue for Tunisian olive oils’ classification according to olive cultivar or physicochemical parameters

“…Besides, due to their cost and the need of skilled technicians, these analytical tools are far away from the economic possibilities of small-and medium-scale olive oil producers. Recently researchers have focused their attention on the potential use of electrochemical devices for olive oil analysis, including quality level assessment and classification, geographical origin discrimination, olive cultivar identification as well as monitoring of olive oils physicochemical and sensorial parameters during storage [16][17][18][19][20][21][22][23][24][25][26][27][28]. Concerning Tunisian olive oils evaluation using electrochemical tools, to the authors' best knowledge, only one work could be found.…”

Chemical composition analysis of the essential oil of Mentha piperita L. from Kermanshah, Iran by hydrodistillation and HS/SPME methods

“…Recent advances in the development of analytical methods based on headspace/solid-phase micro-extraction (HS/SPME) of natural aroma compounds have been reviewed, with a special emphasis on increasing reproducibility (Barié et al 2006;Cimato et al 2006;Johnson et al 2004;Stashenko and Martínez 2007;Taherpour et al 2012;Taherpour et al 2015). A simple, rapid, efficient, and inexpensive method for the determination of essential oil in different samples is headspace-solid phase microextraction/gas chromatography-mass spectrometry (HS/ SPME-GC/MS).…”

“…A simple, rapid, efficient, and inexpensive method for the determination of essential oil in different samples is headspace-solid phase microextraction/gas chromatography-mass spectrometry (HS/ SPME-GC/MS). HS/SPME-GC/MS has been used as an alternative method to determine the essential oils in analytical samples and may be a potential tool for the quality assessment of medicinal herbs like Mentha piperita L (Barié et al 2006;Cimato et al 2006;Johnson et al 2004;Stashenko and Martínez 2007;Taherpour et al 2012;Taherpour et al 2015). Compared with other volatile essential oil extraction studies, the results obtained by HS/SPME-GC/MS have shown high performance in other determining methods of the volatile constituents of the essential oil of Mentha piperita L. (Rohloff 1999;Moradi and Najafian 2015).…”
