Food allergy is becoming a major concern for public health and food industries. To avoid unexpected contact with food allergens, food labeling systems are applied to indicate presence of specific allergens in many countries.
 

Analysis of food allergens (LC-MS/MS)

---

An example of simultaneous analysis of allergens using LC-MS/MS is shown, which contains 150 MRMs for 31 peptides of 13 allergenic proteins identified from 8 foods regulated in the US (milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat and soybeans). They were successfully detected with high sensitivity and selectivity.
