摘要： This specification discloses process for obtaining maltodextrin having DE between 17 and 19.9 and the maltodextrins obtained from the process. The disclosed maltodextrins can be provided as a powder or in shelf stable liquid form. The disclose maltodextrins have a polysaccharide profile similar to those observed for prior art maltodextrins, but make maltodextrin solutions having a high solids content, but reduced viscosity compared to prior art maltodextrins, on equivalent solids-in-solution basis. The process combines adds an alpha-amylase and a pullulanase enzyme to a polysaccharide mixture during a saccharification step. The disclosed maltodextrins make solutions at 50° C. and greater than 65% on a solids dry solids basis having a viscosity between 5,000 and 12,000 cP and having a water activity of less than 0.80.
