Title
(EN) A PROCESS FOR THE PREPARATION OF LONG-CHAIN ALKYLGLYCOSIDES
(FR) PROCEDE D'OBTENTION D'ALKYLGLUCOSIDES A CHAINE LONGUE
Abstract
(EN)
The invention provides a process for the preparation of long-chain alkyl glycosides, comprising reacting at least one substrate selected from a group consisting a carbohydrates and carbohydrates sources and at least one fatty alkanol of at least eight carbon atoms in a medium consisting of at least one glycosidase enzyme having a temperature optimum greater than 60 °C and having thermal stability half-life of greater than 24 hours at 80 °C.
(FR)
La présente invention concerne un procédé d'obtention d'alkyl glucosides à longue chaîne, lequel procédé consiste à faire réagir au moins un substrat choisi dans un groupe constitué de glucides et de sources de glucides avec au moins un alcanol gras d'au moins 8 atomes de carbone dans un milieu constitué d'au moins une glycosidase dont l'optimum de température est supérieur à 60 °C, et dont la demie vie de stabilité thermique est supérieure à 24 heures à 80 °C.
