Authenticity tests of fruit and vegetable products during all processing stages

Authenticity tests of fruit and vegetable products during all processing stages

For the protection of consumers, customers and to safeguard the fair competition along the whole supply chain, it is necessary to examine potential, illegally performed manipulations.





This can include for example the following falsifications:

  • Illegal additives of water, sugar, acids and other ingredients
  • Blending with cheaper foreign fruit products
  • Wrongly declared origin (source / Bio)
  • Use of technologies, which do not correspond to the Code of Practice (CoP) and lead to non-marketable products
  • Wrongly declared aromas


For tests on illegal manipulations, all necessary routine processes (amongst others IFU method) including modern processes like NMR and stable-isotope measurement are available to us.
In conjunction with the AIJN values, specifically applicable for fruit juice assessment, fingerprint analytics and the comprehensive Chelab database, a reliable interpretation of the analysis results is possible.

Authenticity tests of leftover food items

Falsifications are detected in other foodstuffs (including olive oil, fish, bio-foods, milk, coffee, tea, spices, wine, aromas). Manipulations can be reliably verified with the analysis of the genome, the contained proteins or low-molecular metabolites (e.g. flavouring) and the isotope distribution of individual elements (H-C-O-N-S). It is also possible to determine the origin of a foodstuff with specific marker substances or with non-targeted analytics, e.g. NMR technology.
