title: Analysis of food allergen structures and development of foods for allergic patients.
abstract: Food allergy is one of the important health problems, and countermeasures are socially required. We have been undertaking studies on wheat allergens and their epitopes, and have developed a method for producing hypoallergenic wheat flour by enzymatic modification. The hypoallergenic products are now provided to patients. More noteworthy, by taking hypoallergenic cupcakes over a long period, more than half of patients are hyposensitized and become able to eat normal wheat products. This suggests that the hypoallergenic wheat flour can act as anti-allergenic via allergen-specific immunotolerance. This series of studies was followed by expansive research on food allergy: analysis of epitopes of bovine serum albumin (the major beef allergen), isolation and identification of inhibitory peptides for allergen absorption at the intestine, evaluation of hesperetin as an inhibitor of degranulation of mast cells, and the development of PCR detection methods for verifying allergen labeling and for identifying hidden allergic ingredients in processed foods.
