METHOD FOR THE PREPARATION OF GLIADIN AND GLUTANIN RICH FRACTIONS OUT OF GLUTEN IN AN AQUEOUS MEDIUM AND IN THE PRESENCE OF AN ACID

摘要

Method for the preparation of gliadin- and glutenin-rich fractions from gluten in an aqueous medium and in the presence of an acid, characterised in that the 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 shearing actions, through which the dispersion, continuously or not, can be fractionated in gliadin-and glutenin-rich fractions, by which a single gliadin-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.
