Food Authenticity

Sidebar Image

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 illicit 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 illicit profit


Agave Syrup Authenticity

The use of Agave plants, Agave tequilana and Agave salmiana, as a sugar source for the production of tequila and mescal alcoholic beverages has been carried out for years.  However, due to its low glycemic index (GI), and the bad publicity that surrounds high fructose corn syrups (HFCS), these products have recently found another outlet as sugar substitutes.  As with all sugar-rich products there is always a risk that they will be extended with sugars from a cheaper source.

Eurofins utilizes both  Oligosaccharide profile by Capillary Gas Chromatography and SNIF-NMR (Site-Specific Natural Isotope Fractionation-Nuclear Magnetic Resonance) approaches to detect adulteration, both of which are fast and effective methods for identifying atypical profiles.

Oligosaccharide profile is relatively quick and can detect the addition of syrups derived from starch in addition to invert sugar.

The isotopic method provides an additional “high tech” approach to assess the product and will detect the presence of syrups that have been treated in such a way to remove the disaccharide marker peaks.

Fish Authenticity

Traditionally, morphological and histological approaches are used to classify fish and label them for distribution in the marketplace. These approaches can be time-consuming or subjective and inconsistent, especially when performed after cleaning and filleting the catch. Eurofins GeneScan’s DNA-based technology, in contrast, provides accurate and reliable identification of fish species by testing virtually any tissue sample, such as a small piece of fillet.

- Accurate, up-to-date DNA Testing Methods
- Fast, Predictable Delivery of Results, with Rush Service Available Upon Request

Our state-of-the-art DNA laboratory is accredited to the international industry standards ISO/IEC 17025:2005 and we use the FDA recommended DNA “barcoding” technology to confirm your product’s identity and compliance with labeling requirements and determine, unmistakably, that a premium fish fillet like Red Snapper is not a lower valued substitute.

Our DNA testing service complements a comprehensive suite of other Eurofins expert seafood testing services, such as FDA import detention, antibiotic testing, decomposition, microbiology, and more.

Fruit Juice Authenticity

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. 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.

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 the 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.
