Authenticity testing is used to detect the addition of ingredients of lower value than those declared.

As long as trade has existed, economic adulteration of food and beverages has been a subject of concern. Dilution, mislabelling, partial or complete substitution of expensive ingredients are not infrequent practices and can inflict substantial damage on the companies involved if publicised.

Today there are analytical methods available that can be implemented in an effective quality control system to provide some assurance against these fraudulent practices.

Eurofins Analytical Offer

Authenticity analyses are 'made-to-measure' for each product and include basic methods and specific tests, selected to check for likely adulteration practises.

Eurofins' specificity is the use of isotopic techniques, and in particular a method of reference in authentication: SNIF-NMR®. This is one of the most powerful techniques for detecting the adulteration of natural products.

Eurofins also carries out molecular biology techniques and a large number of classic physical, chemical and biological methods: liquid or gas chromatography, spectroscopy (atomic absorption, ultraviolet,...), etc. The laboratory has a very wide range of analytical tools to control product authenticity.

Keeping up to date in authenticity testing requires a constant effort of research and development. With the different types of fraud becoming more and more sophisticated and increasingly difficult to detect by basic analyses since they have often been designed to pass the tests in use, it is essential to resort to advanced analytical techniques to detect the non-compliant products.

A considerable investment in research and development enables Eurofins to apply the most suitable methods to each specific case when controlling the authenticity of a product.

We also offer the possibility of setting up a targeted analytical approach and specific data bank to help protect producers from fraudulent imitations of their products or false declarations of geographic origin, notably in the case of PDO (Protected Denomination of Origin) certification.
