Abstract
The immobilized enzyme for removal of residual cyclodextrins is either a combination of an alpha-amylase and a CGTase which has been immobilized or a fungal alpha-amylase which has been immobilized. In addition to either the fungal alpha-amylase or the CGTase and alpha-amylase, a debranching enzyme can also be employed. When using a debranched enzyme, the debranched enzyme is also immobilized. By using the immobilized enzyme, the step of inactivating the enzyme is eliminated and the contamination due to the inactivated enzyme is also eliminated.
