Method for the preparation of gliadin- and glutenin-rich fractions from glut en in an aqueous medium and in the presence of an acid, characterised in that t he gluten are dispersed continuously or not in water up to a dry substance varying between 5 and 30%, by which * the Ph of the dispersion is monitored between 4,4 and 4,8, and * the gluten- water mixture is submitted to shearin g actions, through which the dispersion, continuously or not, can be fractionated in gliadin-and glutenin-rich fractions, by which a single gliad in- rich fraction with a gliadin/glutenin ratio of at least 2,5 is obtained, and a single glutenin-rich fraction with a gliadin/glutenin ratio of less than 0,8 is obtained. |
