Beschreibung
Zusammenfassung:	The present invention relates to a process for preparing a chemically modified polysaccharide, preferably starch, by using a microdevice. It further relates to the use of a microdevice for the chemical reactions of polysaccharides in heterogeneous mixtures. Examples of chemical modifications are acetylation, oxidation, hydroxypropylation and the like. L'invention concerne un processus de préparation d'un polysaccharide modifié chimiquement, de préférence de l'amidon, mettant en oeuvre un micro-dispositif. L'invention concerne également l'utilisation d'un micro-dispositif pour obtenir des réactions chimiques de polysaccharides dans des mélanges hétérogènes. Des exemples de modifications chimiques sont l'acétylation, l'oxydation, l'hydroxypropylation et analogues.
