摘要：

Pulsed-NMR, X-ray-diffraction and rheological measurements were used to study the structure of systems containing amylose, amylopectin, and their mixtures. It is shown that aggregates whose lifetime was compatible with or exceeded the relaxation time of water molecules were formed during the gelatinization of starch and dissolution of maltodextrin. Evidence is presented to show that the aggregates are formed by amylose macromolecules.
