Beschreibung
Zusammenfassung:	The present invention relates to a process for preparing an alkyl polyglucoside by enzymatic catalysis, using sucrose or an analogue thereof as substrate and making it possible to obtain a large diversity of alkyl polyglucosides in terms of size and structure of the glucoside part thereof, making possible the obtaining of an alkyl polyglucoside with a number of glucosyl units that can be adjusted from 2 to 200 glucosyl units. The process also makes it possible to adjust the linear or branched structure of the carbohydrate part of the alkyl polyglucoside obtained, and also the nature of the glycosidic bonds linking the glucose residues within the carbohydrate part. La présente invention vise un procédé de préparation d'un polyglucoside d'alkyle par catalyse enzymatique, utilisant du saccharose ou l'un de ses analogues comme substrat et permettant d'obtenir une grande diversité de polyglucosides d'alkyle en termes de taille et de structure de leur partie glucosidique, rendant possible l'obtention un polyglucoside d'alkyle avec un nombre d'unités glucosyle modulable de 2 à 200 unités glucosyle. Le procédé permet également de moduler la structure linéaire ou ramifiée de la partie glucidique du polyglucoside d'alkyle obtenu, ainsi que la nature des liaisons osidiques reliant les résidus glucosyle au sein de la partie glucidique.
