The egg protein ovalbumin (OVA) belongs to six most frequent food allergens. We investigated how thermal processing influences its ability to induce allergic symptoms and immune responses in mouse model of food allergy. Effect of increased temperature (70 degrees C and 95 degrees C) on OVA secondary structure was characterized by circular dichroism and by the kinetics of pepsin digestion with subsequent HPLC. BALB/c mice were sensitized intraperitoneally and challenged with repeated gavages of OVA or OVA heated to 70 degrees C (h-OVA). Levels of allergen-specific serum antibodies were determined by ELISA (IgA and IgGs) or by beta-hexosaminidase release test (IgE).
