for many years, assessment of olive oil quality and itsauthenticity confimation has been of great importanceto guarantee olive oil safety in compliance with legislations. these include the investigation of olive oil purityand quality by analyzing several parameters such as fattyacid composition, sterols, phenolic compounds, triacylglycerol and etc, through performing conventional andadvanced hy...

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 ...

The market for imported, premium priced foods has increased dramatically over recent years, as consumers become ever more aware of products originating from around the world. There are many food products that are of superior quality (taste, texture, fragrance etc.) because of the locale in which they are cultivated. Environmental conditions, such as local climate and soil characteristics, combi...

background:confirmation of olive oil authenticity and particularly virgin olive oil has a great importance. several advanced chemical and genetic analyses have been used to monitor especial components; however each has its limitations especially when detecting hazelnut-adulterated olive oil. objectives:the objective of this research is to assess the presence of trace amount of hazelnut oil in o...

a reliable dna extraction method for use on extra virgin olive oil based on a commercial kit was defined, and the possibility of using this dna for fingerprinting the original cultivar was demonstrated. the genetic traceability of single-cultivar virgin olive oil from two cultivars (carolea and frantoio) was achieved by identifying the varieties from which they were produced. this involved the ...

Background: One of the major aspects of traceability in food authenticity assessment is to explore practical methods to find the origin of food. Objective: The aim of the present study was to find a DNA based method for authentication and traceability of food, which are of great importance in health management. Methods: Four different DNA extraction methods were applied to obtain high pure DNA...

Olive (Olea europaea), whose importance is mainly due to nutritional and health features, is one of the most economically significant oil-producing trees in the Mediterranean region. Unfortunately, the increasing market demand towards virgin olive oil could often result in its adulteration with less expensive oils, which is a serious problem for the public and quality control evaluators of virg...

Authentication and traceability of extra virgin olive oil is a challenging research task due to the complexity of fraudulent practices. In this context, the monovarietal olive oils of Protected Designation of Origin (PDO) and Protected Geographical Indication (PGI) require new tests and cutting edge analytical technologies to detect mislabeling and misleading origin. Toward this direction, DNA-...
