CA 2260135

The invention concerns a method for preparing a polydispersed saccharide composition poor in glucose (G), fructose (F) and saccharose (GF) containing at least 93.5% by weight per dry matter of fructo- oligosaccharides constituted by a chain of fructose units with a terminal glucose of formula GF n, n and m being between 2 and 20 and comprising a content of glucose, fructose and saccharose in total less than 5% by weight per dry matter. The method consists in subjecting a substance containing fructanes to partial hydrolysis, the said substance containing fructanes of an average degree of polymerisation not less than 7 and containing glucose, fructose and saccharose in total at most 3.5% by weight per dry matter.

La présente invention se rapporte à un procédé de préparation d'une composition polydispersée de saccharides pauvre en glucose (G), fructose (F) et saccharose (GF) comprenant au moins 93,5 % en poids par matière sèche de fructo-oligosaccharides constitués de chaînes d'unités de fructose de la formule Fm et de chaînes d'unités de fructose avec un glucose terminal de la formule GFn, n et m étant compris entre 2 et 20 et comprenant une teneur en glucose, fructose et saccharose au total inférieure à 5 % en poids par matière sèche, suivant lequel on soumet une matière contenant des fructanes à une hydrolyse partielle, ladite matière contenant des fructanes d'un degré de polymérisation moyen supérieur ou égal à 7 et contenant tout au plus 3,5 % en poids par matière sèche au total de glucose, fructose et saccharose.
