Document Type and Number:

WIPO Patent Application WO/2004/099260

Kind Code:

A1

Abstract:

A process for producing β-cyclodextrin from a substrate other than starch efficiently, which comprises reacting a maltoligosaccharide containing 2-10 glucose units with cyclodextrin glucanotransferase at a temperature below 40 °C in a solution containing an organic solvent which, when added excessively to a β-cyclodextrin solution, precipitates at least 50 % of the β-cyclodextrin.
