Allergens pose a health risk, with up to 5% of the world’s population affected. Food allergen detection and quantification of proteins and protein residues is essential for safety and food labelling purposes. Allergen testing is commonly carried out using ELISA and PCR techniques. Some food preparation processes results in allergens such as eggs and milk undetectable using these methods. These limitations have led to the development of LC-MS/MS as a cutting edge analytical tool in allergen analysis. LC-MS/MS can perform simultaneous multiple allergens detection, with fewer false negatives, greater sensitivity, specificity, accuracy and reliability than common techniques.
