Abstract
The subject of the invention is a process for modifying amylaceous (starchy) materials comprising a stage of chemical fluidification and a stage of stabilization, simultaneous or not simultaneous, these two stages being performed in the dry phase and by the use of a plycarboxylic organic acid. The acid can be chosen particularly from among citric acid, adipic acid, azelaic acid and their mixtures. The process is advantageously performed at a temperature between 90° C. and 170° C., at a pH below 4 and during a total period between 3 minutes and 8 hours. The starchy material subjected to fluidification and stabilization can be cationic.
