Abstract
This invention relates to the problem of water-soluble tablets, wherein dry, edible ingredients having a substantially granular or crystalline structure are blended to form a dry mix which is contacted with an aqueous moistener comprising corn syrup and admixed to form a dough or cohesive powder. The moistened dough or cohesive powder is then mixed with a hydrolyzed starch material to form a flowable composition which can be suitably compressed to form a coherent tablet, using tableting pressures below 200 psig that has a tablet density of about 0.7 to 1.0 grams per cubic centimeter. Optionally, said tablet may be subsequently dried to a stable moisture content to improve storage shelf-life. The resulting tablet is tough, void-free, non-crumbly and rapidly soluble in water.
Claims20
An improved process for preparing a non-friable, rapidly water-soluble tablet, said tablet comprises an edible acidulent and is prepared by compressing a moistened mixture of dry components, wherein the process comprises the steps of:
- (a) preparing a uniform dry mix comprising an acidulant;
- (b) admixing an aqueous moistener comprising corn syrup with the dry mix wherein the amount of moistener is between 2% to 15% of the dry weight of the mix;
- (c) adding a sufficient amount of a hydrolyzed starch material to function as a melting point elevator and also to convert the mixture of step (b) into a free-flowing granular composition;
- (d) compressing the flowable composition of step (c) to the extent necessary to obtain a coherent tablet which has a teblet density of from 0.7 to 1.0 grams per cubic centimeter, as measured on a tablet having a moisture content of less than about 1.5% by weight;
- and
- (e) drying the tablet to a stable moisture content of less than 1.5%.
