Abstract
Abstract The present invention relates to processes for producing syrups or syrup solids containing fructose-terminated oligosaccharides, characterized by subjecting a mixture containing liquefied starch and either fructose or sucrose to the action of immobilized cyclodextrin glucanotransferase E.C. 2.4.1.19.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
64 words
A process for producing syrup or syrup solids containing fructose-terminated oligocaccharides, comprising subjecting a mixture solution of a liquefied starch, which acts as a donor of glucosidic residues, and one or more members selected from the group consisting of fructose, sucrose, isomerized sugar and invert sugar, which act as an acceptor for glucosidic residues, to the action of an immobilized cyclodextrin glucanotransferase (E.C. 2.4.1.19).
Claim 2
Dependent Claim
64 words
A process for producing syrup or syrup solids containing fructose-terminated oligocaccharides, comprising subjecting a mixture solution of a liquefied starch, which acts as a donor of glucosidic residues, and one or more members selected from the group consisting of fructose, sucrose, isomerized sugar and invert sugar, which act as an acceptor for glucosidic residues, to the action of an immobilized cyclodextrin glucanotransferase (E.C. 2.4.1.19).
Claim 3
Dependent Claim
28 words
A process as set forth in claim 1, wherein said cyclodextrin glucanotransferase is produced by Bacillus macerans, Bacillus megaterium, Bacillus circulans, Bacillus polymyxa, Bacillus stearothermophilus, or Klebsiella pneumoniae.
Claim 4
Dependent Claim
75 words
A process as set forth in claims 1 or 2, wherein a mixture solution, concentration in the range of 10 to 50 w/w% and containing a liquefied starch, D.E. 3 to 40, and one or more members selected from the group consisting of fructose, sucrose, isomerized sugar and invert sugar in a ratio of donor vs. acceptor in the range of 0.2 to 5 d.s.b., is subjected to the action of said immobilized cyclodextrin glucanotransferase.
