Dutch cheese

Food fraud and Composition

Is Tuscan olive oil really from Tuscany? And are these organic eggs really organic? These are examples of the type of authenticity and nutrient related questions which RIKILT deals with on a regular basis.

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:

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

Fertilizers

In the Netherlands we have a surplus of fertilizers. The allowed quantity and quality of fertilizers in the ground is described in a special law. Failure to follow this law could harm the environment.

Task RIKILT:

  • Study composition and authenticity
  • Quality check commercial labs that analyse on phosphorus and nitrogen
  • Calculators helps people fertilizer to respond to this law regarding contaminants.
