Molecular biology for food authenticity

Molecular biology methods enable species identification and the detection of undeclared ingredients. Eurofins Food & Feed Testing laboratories support you with DNA-based testing methods to verify authenticity, prevent fraud and support compliance with labelling and regulatory standards.

Molecular biology applications for authenticity testing

Our molecular biology laboratories apply advanced DNA-based testing techniques to verify the species and varietal identity of food and drink products. Using methods such as DNA fingerprinting and species-specific PCR, we compare the genetic profile of a sample against our extensive, curated reference database. 

We can apply this method to many foods and beverages, including, but not limited to:

  • Meat species testing - Detect undeclared or substituted meats, ensuring accurate ingredient labelling and compliance with local and/or EU food law
  • Fish species testing - Verify that fish species match the product label, helping to prevent fraudulent substitution of lower-value species
  • Botanical variety testing - Confirm fruit, vegetable, and plant varieties, substantiating origin and varietal claims in high-value products and supporting seed industries and breeders with a wide and flexible range of genotyping platforms and services
  • Grain and cereal verification - Authenticate wheat, rice, maize, and other cereal types for both quality and origin control
  • Processed food testing - Detect animal or plant DNA in many cooked, processed, or mixed-ingredient products, depending on processing level and sample type

Advantages of DNA-based authenticity testing

  • High sensitivity and specificity - Detects trace amounts of DNA, even in processed foods
  • Broad applicability - Suitable for raw ingredients, processed goods, and complex mixtures
  • Rapid and reliable - Fast turnaround with validated, and where applicable, ISO-compliant methods
  • Robust results - Provides high-quality, accredited data to support compliance monitoring, brand protection, and due diligence programmes
  • Regulatory acceptance - Performed in accredited laboratories using validated methods, providing results that support compliance checks and regulatory investigations
  • Fraud prevention - Supports robust supply chain monitoring and helps mitigate economic adulteration
