Allergenicity of Foods Although any food protein can be potentially allergenic, relatively few cause most allergic reactions. In addition, an allergenic protein can only induce an allergic reaction in an allergic person who has been sensitized to it.
In this review the impact of processing (heat and non-heat treatment) on the allergenic potential of proteins, and on the antigenic (IgG-binding) and allergenic (IgE-binding) properties of proteins has been considered. A variety of allergenic foods (peanuts, tree nuts, cows’ milk, hens’ eggs, soy, wheat and mustard) have been reviewed.
