Abstract
A compressible starch, useful as a binder for tablets prepared by direct compression or dry granulation or as a binder-diluent for capsules, is prepared by treating a cold-water-insoluble, granular starch (e.g., corn or waxy corn starch) with an acid, and/or alpha-amylase enzyme at a temperature below the starch's gelatinization temperature. The treated starch is characterized by altered, weakened granules with a less dense interior and disrupted surface. The compressible starch when admixed with a wet granulation binder (e.g., pregelatinized starch) is useful as a binder for tablets prepared by wet granulation as well as direct compression or dry granulation or as a binder-diluent for capsules.
