The reliable analysis of food allergens is the prerequisite for ensuring compliance with legally required labelling regulations. This can be carried out by means of either protein or DNA detection. Protein detection has the advantage of directly detecting the allergenic component and can currently be carried out using immunological (ELISA/simple rapid tests) or mass spectrometry-based (MS) techniques. DNA detection is indirect, but allows the presence of food allergens to be validated through the use of another marker. The advantages and disadvantages of each method need to be considered on a case-by-case basis.
