In recent years, food allergies are on the rise due to the change in food production and environment. Several products are manufactured in the same facility and cross-contamination is an issue to be monitored. While impurities with allergenic matter are negligible for many people, they can be a serious health risk for others and need to be reliably identified.
When it comes to the detection of allergens, ELISA-based methods the most common methods despite their bias in terms of cross-reactivity. Realtime-PCR allergen detection can score with superior specificity here, as detection happens on DNA level instead of protein level. DNA-based detection is also superior in terms of acquisition of sample material: allergenic proteins are mostly present in traces and may either be denatured during food processing or overlain by other cross-reactive proteins in the sample. DNA, however, remains unaltered and can be detected down to single copies of a target sequence. Therefore, testing food for allergens with realtime-PCR is an easy, sensitive and specific addition to conventional ELISA assays if not an adequate substitute.
