摘要：
Low levels of high-molecular-mass dextrins in starch hydrolysates can be detected by high-performance anion-exchange chromatography with pulsed amperometric detection in spite of their low responses by dialysis of the starch hydrolysate and fractionation of the resulting adialysate with ethanol (final concentration 30-80% at 6degreesC). In doing so, dextrin fractions with a relatively narrow molecular mass distribution were obtained. (C) 2003 Elsevier Science B.V. All rights reserved.
