Abstract
Prolonged incubation with sucrose as an acceptor and cycloinulohexaose as a donor at a high concentration of cycloinulooligosaccharide fructanotransferase afforded a series of fructooligosaccharides. Their chain-length distribution extended over 10 degrees of polymerization when the donor concentration was increased to 120 mM. Increasing the acceptor concentration proved effective in improving the yield of inulin-type oligosaccharides because hydrolysis was suppressed.
