This book explores the recent advances and integrations in molecular technology in food research platforms, which have revolutionized the way we discover and trace potential allergens in our food and drugs and how we utilize that for diagnosis and management. These different technologies for global allergenomic profiling in different kinds of food are discussed, including mass spectrometry, chromatography, and nuclear magnetic resonance. The book also addresses multiomics research with bioinformatics strategies in food allergy in terms of allergen characterization and quantitation, and covers applications in food allergy research from discovery to routine analysis.
