Food allergies and intolerances are not uncommon; therefore, correct labelling of allergenic ingredients is becoming more and more important. The law stipulates the allergenic ingredients that need to be labelled. The WESSLING food safety experts provide the complete range of tests for allergens.

We are happy to answer all your questions and support you with the following analyses:



Egg protein

Fish ingredients

Peanut protein

Soya protein

Lactose free



Almond protein

Hazelnut protein

Walnut protein



Brazil nut


Macadamia nut


Mustard seed protein

Sesame protein





Genetically modified organisms (GMO)

A large number of agricultural raw materials are now also sourced from genetically modified organisms. However, acceptance by consumers in Germany and the EU for these products remains low. WESSLING offers modern analytical methods and extensive expertise in the detection of genetic modifications. In addition to specific detection and quantification methods, screening methods are available to detect a large number of genetically modified organisms. As a VLOG-approved laboratory, we meet all the requirements for VLOG (Verband Lebensmittel ohne Gentechnik e.V., the German association for genetically unmodified food) to test your feed and food in accordance with current standards.

Animal species identification and sexual determination

Standardised laboratory procedures are available for the differentiation of animal species. The most commonly used techniques for animal species identification are based on ELISA and PCR methods.

An alternative technique used is MALDI-TOF/MS. For some years now, this technique has been utilised mainly for the identification and typing of microorganisms, but it can also be used to differentiate animal species. Using MALDI-TOF, animal species can be identified by their molecular fingerprints, so-called protein fingerprints. The routine use of this method is based primarily on a comprehensive database. If no commercial databases are available, the user can create corresponding reference spectra. Various institutions have created databases for the determination of animal species in milk and cheese and the identification of fish species and food insects, some of which are publicly accessible. These databases give reason to hope that food adulterations will be detected faster and more efficiently in the future.

Sexual determination in meat can also be conducted via PCR (polymerase chain reaction).

All the above-mentioned procedures can be conducted in the WESSLING laboratories. The experts at WESSLING are pleased to advise companies in the food industry on the selection of the optimum solutions for their problems and on all other analytical questions concerning the safety of their food.
