Patent ID: 7063976

Claim:
A process for producing fructooligosaccharides comprising 1-kestose (GF2), nystose (GF3), and fructofuranosil nystose (GF4), comprising the steps of a) inoculating the spores of the fungus Aspergillus niger 489 having the deposit designation of PTA-5032 in a liquid or semi-solid culture medium; b) cultivating the inoculated fungus of step (a), in order to promote the growth of said fungus with the formation of mycelium and the production of beta-fructofuranosidase enzyme; wherein said fungus is incubated at a temperature of 30° C. for a period of 96 to 120 hours; c) separating the beta-fructofuranosidase enzyme from the mycelium and from the culture medium; and d) transfructosylating the beta-fructofuranosidase enzyme to produce said fructooligosaccharides.
