RIKILT inspects the authenticity of foodstuffs, animal feed and fertilisers and verifies the identity of these products. We investigate:

• Compositional authenticity, for example the origin of fish species, N-replacements in milk, functional components in special honey, mineral fertilisers in manure
• Processing characteristics such as freezing history
• Geographical origins, whether a product is from an EU or non-EU country or region.
• Production methods e.g. organic eggs, sustainable palm oil, halal, durable
  
• Typical characteristics of artisanal products, such as farmers cheese from Leiden (the origin of this cheese is guaranteed by pressing the municipal insignia into the cheese)
  

Applied techniques include:

• Mass spectrometry, such as:
  •         GC(-MS)
  •         LC(-MS)
  •         PTR-MS
  •         ICP-MS
  •         IR-MS
•     NMR
•     Infrared technology
•     DNA based methodology
•     Visual evaluations

Specific markers and the increasing use of fingerprint technology combined with advanced statistical methods result in up-to-date analyses.
