Abstract: The present disclosure relates to inhibited porous granular starches having desirably high porosity. One aspect thereof is a method for making an inhibited porous granular starch product, that includes hydrolyzing a granular starch feed to a degree of hydrolysis of 20-75% using one or more enzymes including one or more of a glucoamylase and an alpha-amylase; wherein the inhibited porous granular starch product has a porosity of 10%˜50% as measured by change in water uptake as compared to the granular starch feed and a sedimentation volume in the range of 20 mL/g to SO mL/g. Another aspect of the disclosure is inhibited porous granular starch product having a water uptake of at least 1.0 g water/g starch and a sedimentation volume in the range of 20-80 mL/g. inhibited porous granular starches can be advantaged over conventional starches in that they can have increased viscosity at lower mass loadings.

Abstract: The present disclosure relates to pregelatinized starches having a high degree of process tolerance, and methods for making and using them. In one aspect, the disclosure provides a pregelatinized starch having no more than 15 wt % solubles and a sedimentation volume in the range of 15 mL/g to 45 mL/g, the pregelatinized starch comprising starch granules, wherein at least 50% of the starch granules swell but do not substantially fragment when processed in 95° C. water, the pregelatinized starch being in a substantially planar form. In another aspect, the disclosure provides a pregelatinized, drum-dried starch having no more than 15 wt % solubles and a sedimentation volume in the range of 15 mL/g to 45 mL/g, the pregelatinized starch comprising starch granules, wherein at least 50% of the starch granules swell but do not substantially fragment when processed in 95° C. water.
