allergen detection methods

Allergen detection methods identify traces of common allergens like peanuts, dairy, or gluten in food. Techniques such as enzyme-linked immunosorbent assay (ELISA) use antibodies that specifically bind to allergen proteins, producing a measurable signal if allergens are present. Molecular methods like PCR detect allergen DNA, confirming their presence even if proteins are broken down. These tests help ensure food safety by verifying that products meet allergen labeling standards and reduce the risk of allergic reactions for sensitive individuals.
