Patent ID: 7084131

Claim:
A method for preparing a polydispersed saccharide composition which comprises providing a material containing inulin with an average degree of polymerization equal to or greater than 7, and containing at most 3.5% by weight relative to the dry matter in total of glucose, fructose and saccharose, which is completely solubilized in water, and subjecting said material to partial hydrolysis with an enzymatic preparation having endo-inulinase activity, at a temperature of 58 to 62° C. and at a pH of 5.2 to 5.6, thereby yielding directly, without using a chromatography separation, a polydispersed saccharide composition comprising at least 93.5% by weight, relative to the dry matter, of fructo-oligosaccharides consisting of chains of fructose units of formula F m and of chains of fructose units with a terminal glucose of formula GF n, n and m being between 2 and 10, comprising more than 43% by weight relative to the dry matter of fructo-oligosaccharides of formula F m and comprising a glucose, fructose and saccharose content in total of less than 5% by weight relative to the dry matter, an aqueous solution of which at a concentration of 75% by weight relative to the dry matter remains clear during storage at room temperature.
