Raman spectroscopy demonstrated that the anthocyanins induce in gliadins conformational changes of different extents. The treatment with any of the considered anthocyanins altered the distribution of the disulphide conformations; in addition, malvin and pelargonin provoked a significant decrease of the β-turns content. Since both these structural elements have been related to gluten allergenicity, anthocyanins appeared interesting molecules, potentially able to decrease allergen immunoreactivity.
