ABSTRACT



Kinetics of amylolytic hydrolysis of autoclaved and extruded potato starch using alpha-amylase and pullulanase mixtures were described. Maltodextrins with dextrose equivalent of 3, 5, 8 and 12 were obtained and their sugar compositions with HPLC method were analyzed. The low molecular sugar (PD 1-2) and oligosaccharide (PD 3-8) contents as well as relationship between dextrose equivalent of maltodextrins and oligosaccharide contents were determined.

Key words: maltodextrin, oligosaccharide, amylase, pullulanase, hydrolysis..
