Soybean β‐conglycinin as the main allergen in a patient with food‐dependent exercise‐induced anaphylaxis by <i>tofu</i>: food processing alters pepsin resistance

Abstract

We identified beta-conglycinin as the causative allergen in a patient with FDEIA induced by tofu. The difference in resistance to pepsin digestion between tofu and soy milk suggests that the presence of undigested allergens in the digestive tract is a prerequisite for the development of FDEIA.
