Eurofins is the world leader in Authenticity Testing by providing a comprehensive portfolio of methods dedicated to the detection of adulterants in fruit juice. Our technical expertise and market knowledge in various industries allow our clients to verify compliance with the latest regulations in each country and market, both for fruit juice concentrate and finished product.

Economic adulteration has long been a subject of concern. Additionally, problems with dilution, mislabeling, and partial or complete substitution of expensive ingredients are not infrequent practices and can inflict substantial damage on the companies involved.

What are the driving forces for adulteration?

  • The opportunity to make an elicit profit
    • Presence of cheaper adulterants
  • Premium foodstuff in short supply
    • Lack of raw material (fruit/honey/agave) to fulfill an existing contract
    • High commodity prices
  • Companies buying from unknown suppliers
  • Likely to be more issues if there is a long supply chain
  • Companies not testing their incoming raw materials
  • Supplier attitudes
  • The opportunity to make an elicit profit

Our state-of-the-art laboratories employ the latest analytical technologies that provide the robustness and sensitivity needed for detection of adulterants in juice products.

Targeted & non-targeted approach:

  • Organic acids profile
  • Sugar profile
  • Polyphenols and Anthocyanins fingerprint
  • Polymethoxylated Flavones for lemon juice adulteration with lime juice
  • Oligosaccharide profile by Capillary Gas Chromatography to detect addition of inulin syrup, invert sugar and HFCS addition
  • Isotopic analysis
  • Patulin
  • Mineral profile
  • Artificial color scan
  • Heavy metals
  • Pesticides residues

In addition to our excellent chemical analyses, Eurofins utilizes both SIRA (Stable Isotope Ratio Analysis) and a unique tool, SNIF-NMR (Site-Specific Natural Isotope Fractionation-Nuclear Magnetic Resonance), both of which are fast and effective methods for identifying atypical profiles.
