Is this really a high-quality olive oil? This is the question many consumers ask themselves when they stand in front of the shelves in the grocery store. Often, the next step is to reach for the highest quality grades - virgin and extra-virgin olive oils. These are supposed to be particularly aromatic and healthy due to the gentle mechanical cold pressing of the olives. In addition, they must fulfill numerous quality criteria according to an EU regulation ((EEC) No. 2568/91). If you then decide to buy a bottle with an indication of origin, you are supporting the countries of production with your purchase. But is the information on the labels correct?
Unfortunately, it has often been shown in the past that counterfeiting of the popular cooking oil is a huge problem and harms both customers and producers. In order to verify the quality and authenticity of olive oils, FoodQS offers a modern and comprehensive nuclear magnetic resonance spectroscopy (NMR)-based olive oil analysis at its site in Bayreuth.
The advantage of this technology is that it provides important and relevant authenticity and quality parameters in a very short time and on the basis of a single cost-effective measurement. These are then summarized in a clear test report.
For the general characterization of the olive oil, this test report includes the following parameters:
Our experts in the field of "food analysis by NMR" additionally check the olive oil for consistency with the reference data with regard to:
By comparing a sample with an extensive in-house reference oil database, the plausibility of the origin.
Currently, this is possible for oils from the three largest producing countries:
It is our concern to offer you a cost-effective and fast analytics, which provides all relevant results and which represents an added value for your quality efforts. Of course, we also offer a corresponding analysis for other vegetable oils.
If required, additional parameters such as residues (pesticides, PCBs, PAHs...), heavy metals or microbiological criteria can be examined in addition to the NMR analysis.
