Abstract
The present invention relates to an ingestible aggregate comprising a pre-swelled substantially anhydrous hydrocolloid and a substrate. More particularly this invention relates to an aggregate having as a substrate a dietary fiber and/or drug wherein the composition can be administered in a therapeutically effective amount. Hydrocolloids useful include natural and modified gums, celluloses, modified celluloses, pectins, mucillages, modified starches, noncellulose polysaccharides, algal polysaccharides and mixtures thereof. The aggregate should be in the size range of about 4 to about 70 U.S. mesh. The unpleasant taste and mouthfeel of the fiber and/or drug is effectively masked and substantial hydration is delayed until the composition reaches the stomach. The compositions are substantially more palatable, devoid of graininess, bitterness or fibrous texture. The pleasant taste of the composition encourages patient compliance with their fiber or drug therapy.
