Proteomic applications in food allergy: Food allergenomics

Purpose of review To familiarize the reader with the recent developments in the identification of food protein allergens by proteomics mass spectrometry-based methods, named allergenomics. Recent findings The proteomic analysis of food protein allergens has became a hot topic in the food safety field in recent years. Indeed, food allergies represent a current and relevant problem in clinical medicine. Several food allergenomics studies have recently been performed, aiming at better understanding the cause of sensitization to cow's milk in breastfed infants and at assessing both the safety of food (e.g. transgenic) and in particular the allergenic properties of processed fish and seafood. Summary Food protein allergen characterization and quantification, together with the immunoglobulin E epitope mapping, will contribute to the diagnosis/prognosis of food allergy and will lead to a better safety assessment of foods (e.g. novel transgenic foods).
