Abstract
Pregelatinized granular starches and flours are thermally inhibited by dehydrating a starch to anhydrous or substantially anhydrous and then heat treating the dehydrated starch at a temperature and for a time sufficient to inhibit the starch. The starch may be pregelatinized prior to or after the thermal inhibition using methods known in the art which retain the granular integrity. Preferably, the pH of the starch or flour is raised to 7.0 or above prior to the thermal inhibition steps. The dehydration step may be carried out by directly heating the starch, by extracting the starch with a solvent, or by freeze drying the starch. Preferably protein and/or lipids are removed prior to or after the thermal inhibition.
