Thermal processing effects on peanut allergen Ara h 2 allergenicity in mice and its antigenic epitope structure.Ara h 2 was purified from peanuts that were thermally treated by various processes, including boiling, glycation, frying and roasting.  The allergenicity of Ara h 2 in Balb/c mice and the influence of thermal processing on the structural characteristics, and binding capacity of three core antigenic epitopes were studied.  These results indicate that thermal processing causes alteration of the protein structure and core epitopes of Ara h 2, and may affect its allergenicity.
