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 & herbs
  • 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.
