  • Publication number: 20230295679
    Abstract: 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.
