Method for purifying cyclic inulooligosaccharide.

摘要

An exo-type enzyme having an ability to cut beta -(2->1) fructoside bond or a microorganism which produces the enzyme is allowed to act on a saccharide solution containing cyclic inulooligosaccharide in which fructose molecules are bonded through beta -(2->1) bond in a cyclic configuration, and other saccharides such as monosaccharide, disaccharide, linear oligosaccharide and inulin, and then the cyclic inulooligosaccharide is collected from an obtained saccharide solution. Thus cyclic inulooligosaccharide can be purified inexpensively at a high yield without using any solvent.
