  • Patent number: 4857331
    Abstract: A sugarless ingestible gel confectionary delivery system which includes a pectin gel component, an algin gel component and a polymer network gel component in amounts sufficient to form a gel confectionery unit. The inventive gel confectionery unit has reduced intrinsic viscosity prior to gelation which permits the inclusion of an edible insoluble solid in an amount sufficient to strengthen the internal combination pectin-algin gel network and to bind internal moisture sufficiently to enhance mold removal capabilities. The delivery system also includes hydrogenated starch hydrolysates. The delivery system may also include a further active ingredient such as a drug, medicament, or nutritional supplement. The product and method of the present invention also includes a composition in which the gel delivery system can be molded directly in the receptacle which is used to dispense the confectionery unit to the consumer.

  • Patent number: 4851392
    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 platable, devoid of graininess, bitterness or fibrous texture. The pleasant taste of the composition encourages patient compliance with their fiber or drug therapy.

  • Patent number: 4828857
    Abstract: A method of preparing a delivery system wherein in the core material is a sweetener, flavoring or the like and is protected by a matrix coating which process comprises:(A) forming an agglomerate of the core material in a hydrophobic matrix coating comprising the steps of melting the hydrophobic coating and dispersing the core material uniformly therein; feeding the dispersion into a heat controlled high pressure spray nozzle; atomizing the dispersion under controlled pressure to maintain the particle size between about 200 to about 30 mesh; collecting the congealed, dry spherical-like particles; and(B) coating the agglomerated particles by conducting the particles through a stream of air passing through a zone of atomized droplets of a second hydrophobic material.
