Wheat in baked goods may prevent the egg from being absorbed and recognized by the body.Įgg allergy is generally outgrown in childhood. One study noted that patients who were baked-egg tolerant and regularly consumed baked egg were able to tolerate all forms of egg faster than those who could not tolerate baked egg. However, ovomucoid is heat-stable, and patients who are allergic to ovomucoid tend to not tolerate baked egg. Ovalbumin in particular is broken down and not able to bind IgE after such heating. strained egg yolk is not safe for an egg allergic individual).Įgg allergy is unique in that 70 to 80 percent of egg-allergic patients may tolerate egg that has undergone extensive baking (greater than 350 degrees F for 30 minutes, called “baked egg”) and are thus able to consume baked egg in pastries, breads, and cakes. Egg yolk cannot be safely separated from residual egg white protein allergens (e.g. Egg yolk is an allergen but is not responsible for many reactions. There are three major proteins of concern in egg white: ovalbumin, the major allergen present in the highest proportion ovomucoid, another egg white protein responsible for the majority of allergic reactions and ovotransferrin. There are as many as 23 proteins in egg, but most of the allergens are in the egg white, not the egg yolk. Egg allergy (hen/chicken egg), along with milk, is one of the most common allergies in children.
