Abstract
A multi-step process for producing maltopentaose involving the dissolution and dissociation of amylose in an organic solvent, the hydrolyzation of amylose into lower molecular weight components, the precipitation of those components, and the reaction of an aqueous solution of the precipitate with amylase obtained from Bacillus licheniformis to produce a solution containing a high concentration of maltopentaose. This solution is then fractionated to produce a maltopentaose rich solution which is dried to produce maltopentaose.
