Zusammenfassung:	High solids maltodextrin syrups, some of which are useful as the base for remoistenable adhesives, are prepared by a high solids alpha amylase enzyme conversion process. They are characterized by their high solids content (at least 55 wt. %) and light color. A granular chemically derivatized, optionally converted, starch having a degree of substitution of greater than about 0.01 and less than about 0.5 is used as the starting material. The maltodextrins have a reducing sugar content of about 5-19 dextrose equivalent and a distinct polymodal molecular weight distribution. When a granular highly esterified starch (D.S. of 0.5-1.8) is used as the starting material in the high solids process, the resulting enzyme-converted, esterified maltodextrins are characterized by their improved water dispersibility.
