Molecular biological investigations in food and animal feeds

In our molecular biology laboratory we use state-of-the-art methods to examine samples for the following parameters, among others:

Safe allergen management plays a central role in the production of food. Only the reliable detection of allergens in the trace range enables the correct declaration of food. Our laboratory quickly and reliably detects allergenic ingredients using highly specific ELISA and PCR methods.

The analysis of a sample for genetically modified organisms is performed by polymerase chain reaction (PCR). This allows the reliable detection and quantification of artificially introduced DNA sequences in organisms. The determination of GMO-free status, the evaluation of marketability and correct labelling is made possible.

The determination of the animal species (authenticity test) according to the declaration of meat products or ready meals represents a constantly current task in quality control. With the help of sensitive, molecular biological methods, animal species determinations and tests for admixtures of (undeclared) animal components can be carried out.

The identification of the plant species in a foodstuff or a starting product is used, among other things, to test product authenticity or to carry out internal production controls.

Molecular biological methods provide fast results and are suitable for trace analysis. We therefore use them in particular for the rapid analysis of pathogenic microorganisms. Within 24-30h after sample receipt you will receive the results for the detection of:

  • Salmonella
  • EHEC/STEC
  • Listeria monocytogenes


Within 48-72h after sample receipt, the results are available for detection from Yersinia enterocolitica.

The examination for further pathogens is possible on request.

Hormone-active substances represent an ever-increasing environmental problem. In many cases, their effect on humans has not yet been sufficiently investigated. Biotests can be used to detect all hormone-active compounds (endocrine disruptors) in a sample as a sum effect.

The examination of substances with a damaging effect on the genetic material (DNA) is carried out with a rapid and proven biotest. In addition to the genotoxic effect of the substances, the genotoxicity of the metabolites is also determined. This allows an evaluation of the sample with regard to its genotoxic potential.
