Résumé

The factors that determine the digestion rate of starches were revealed using different forms of starches and a mixture of α-amylase and amyloglucosidase. Gelatinized starch samples with a degree of gelatinization (DG) from 12.2 to 100% for potato starch and from 7.1 to 100% for lotus seed starch were obtained. With an increasing DG, the short- and long-range molecular orders of both starches were disrupted progressively. The first-order digestion rate constant (
