Analytical generalities

For the detection of the presence or absence of allergenic substances causing residual or cross-contamination allergies or intolerances, there are many variants of analytical techniques.

The basic starting point for allergen management is the visually and physically clean standard, which, after regular evaluation and validation by one or more analytical methods, can be a good basis for safe operation.

If in a visually clean equipment, the presence of an allergen is not detected above a specific detection limit, and if the sampling is representative, the sample can be used as a basis for limited quantitative risk management.

Analytical methods and techniques can also be used to determine the composition of materials, for due diligence in the use of product claims and to quantify batches.

It is recommended that all users keep up to date with the latest regional and national developments and innovations in terms of methods, matrices and analytical validation, as there is a continuous development of allergen testing and analysis technolo
