Abstract
Natural maple saps and maple syrups are contacted with an immobilized isomaltulose-forming microorganism to convert at least 20% of the sucrose contained in the sap or syrup to isomaltulose. The microorganism may be immobilized on calcium alginate and prepared as a column through which sap or syrup flows. The resultant isomaltulose-containing solutions are concentrated to produce reduced or low glycemic index sugar syrups, semi-solid and solid sugar products.
