Beschreibung
Zusammenfassung:	One subject of the present invention is a process for modifying a composition comprising at least one plasticized flour according to which, in an extruder, at least said plasticized flour is reacted with at least one organic anhydride, the amount of organic anhydride incorporated representing between 30 and 670 parts by dry weight per 100 parts by dry weight of flour. La présente invention a pour objet un procédé de modification d'une composition comprenant au moins une farine plastifiée selon lequel, dans une extrudeuse, on fait réagir au moins ladite farine plastifiée avec au moins un anhydride organique, la quantité d'anhydride organique incorporé représentant entre 30 et 670 parts en poids sec pour 100 parts en poids sec de farine.
