Authenticity of Olive Oil and other Vegetable Oils
10-12 April 2016, Nuremberg, Germany
In addition to the quality assessment of olive oil and other vegetable oils, the need for authentication is of major concern for
consumers and the food industry. Not only expensive and valuable oils such as olive oil or argan oil, but also cheaper oils purchased
in high quantities may be subjected to different kinds of food fraud. The aim of oil authentication is to protect the consumer from
adulteration and the industry from unfair competition.
Today, olive oil is the only oil in commerce for which a legal framework exists with many official methods to characterize the oil quality.
For all other oils only national or international standard definitions of the quality such as the Codex Alimentarius are available.
Traditionally, the characterization of oils has been based on one or more constituents such as fatty acids, phytosterols, tocopherols, waxes,
the triacylglycerol composition or markers such as sesamolin in sesame oil, This information is not enough to answer all the questions by
comparing with known samples or legally established limits. In these times, not only the identity of oils is of interest due to its
labeling as “organic”, “virgin”, “GMO-free”, but also the specific geographic regions they are from are important purchasing arguments.
Therefore, questions regarding the geographical origin, genetic variety, quantification of blends of vegetable oils or detection of
refining treatments have to also be answered, ideally by the use of fast and rapid methods that are easy to handle.
More and more general methods come into the focus of interest which can provide information on more than one parameter at the same time.
Such methods are fingerprinting techniques like NIR, MIR and NMR spectroscopy, but also chromatographic methods like GC, GCxGC, LCxGC or LC
with mass selective detectors are in use, which analyze the metabolic profile of oils. In combination with chemometric techniques such as
Principle Component Analysis or Linear Discriminant Analysis these methods can be used to identify parameters of high discriminatory
power to answer the above mentioned questions.
It is widely accepted that there is a strong need for the harmonization and validation of methods to face the problems concerning the
authenticity confirmation of olive oils and other high price vegetable oils. A part of the Horizon 2020 program initiated by the European
Commission (SFS14-2014/2015) is open to development, validation and harmonization of analytical methods and quality parameters for olive
oil that specifically address technical authenticity issues:
These issues concern in particular
1) The blend of extra-virgin olive oil or virgin olive oil with soft deodorized olive oil,
2) The blend of extra-virgin olive oil or virgin olive oil with other vegetable oil. Beyond the case of olive oil, there is also a strong
need for better coordination of research in the area of food authenticity, integrity and traceability across the food supply chain between
Member States and Associated Countries.
The aim of the symposium is to give an overview on the different aspects of authenticity of olive oil and other vegetable oils, from the legal
regulations and approaches to traceability via the statistical techniques to the general and specific analytical aspects. This symposium will
present new and fast methods to proof the quality and authenticity of olive oil and other edible oils and the participants will have the chance
to discuss with outstanding experts the different aspects in the field of authenticity.
This symposium is aimed at all people working as legal key opinion leaders, in official and commercial laboratories or in official or
commercial food control or food industry. At the end the participants should be provided with the newest information on authenticity and the
latest findings in order to make the market of edible oils fit for the future.
We look forward to welcoming you in Nuremberg in April 2016.
