Different food processing can alter the antigenicity of food proteins in different ways, either by causing conformational changes in the structure of the epitopes (Rahaman, Vasiljevic, & Ramchandran, 2015) and/or by changing their digestibility (Soler-Rivas & Wichers, 2001). Commonly wheat is subjected to various processes e.g. baking, extrusion, cooking etc. before consumption.
