Abstract:
A process for producing a saccharide composition containing maltohexaose and/or maltoheptaose, comprising:(a) reacting starch with a maltohexaose- and maltoheptaose-forming amylase to form maltohexoase and/or maltoheptaose in the presence of calcium ion, said amylase having an activity of throughout the enzymatic reaction; forming primarily maltohexaose and maltoheptaose as main end products from starch in the absence of a starch debranching enzyme, and not hydrolyzing pullulan, maltohexaose and lower molecular oligosaccharides than maltohexaose wherein the reacting with starch is promoted by calcium ion and said enzyme is stabilized by calcium ion; and(b) collecting the resultant saccharide composition containing maltohexaose and/or maltoheptaose.
