Varietal authentication of virgin olive oil: Proving the efficiency of sesquiterpene fingerprinting for Mediterranean Arbequina oils

چکیده
Virgin olive oil (VOO) is a highly appreciated product fundamental in the Mediterranean diet. Since its sensory attributes are greatly influenced by cultivar, varietal authentication of VOOs needed to protect consumers from misleading information. The present study aims evaluate suitability sesquiterpene hydrocarbon (SH) fingerprint as VOO cultivar marker beyond geographical, agronomical and processing conditions. was mainly focused on Arbequina oils. SH profile more than 400 6 counties 38 different cultivars coupages analysed Headspace Solid Phase Microextraction-Gas Chromatography-Mass Spectrometry (HS-SPME-GC-MS). Partial Least Square-Discriminant Analysis (PLS-DA) classification models were built with aligned chromatograms. A binary PLS-DA model distinguish ‘Arbequina’ oils those other (non-‘Arbequina’ class) it externally validated. results external validation showed 95.1% overall correct confirming screening method for VOO. Also, discrimination capacity fingerprinting authenticate preliminary explored promising obtained. • Sesquiterpene enables authenticating multi-origin Genetic environmental factors have distinct effects fingerprint. Minor relevant differentiate samples cultivars. Fingerprinting approach an optimal fraction.

Varietal Tracing of Virgin Olive Oils Based on Plastid DNA Variation Profiling
Olive oil traceability remains a challenge nowadays. DNA analysis is the preferred approach to an effective varietal identification, without any environmental influence. Specifically, olive organelle genomics is the most promising approach for setting up a suitable set of markers as they would not interfere with the pollinator variety DNA traces. Unfortunately, plastid DNA (cpDNA) variation of ...
متن کاملVirgin olive oil and nutrition
Numerous medical studies (a study in seven countries, Monika study, Dart studies, etc. ) have shown that olive oil is one of the most important ingredient of "Mediterranean diet" associated with a reduction in cardiovascular disease and certain types of cancerous diseases. Nutritional and health value of virgin olive oil is attributed to the large proportion of monounsaturated fatty acids (main...

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Antioxidants in Greek Virgin Olive Oils
Greece is ranked third after Spain and Italy in virgin olive oil production. The number of Greek olive cultivars-excluding clonal selections-is greater than 40; however, more than 90% of the acreage is cultivated with 20 cultivars, adapted to a wide range of environmental conditions. Greek virgin olive oils, produced mainly with traditional, non-intensive cultivation practices, are mostly of ex...
