Abstract: A method for increasing the rate of solubility of fumaric acid by grinding the fumaric acid to a set particle size, combining it with a wetting mixture of water, a polyol and an alkali. The product resulting therefrom may be further treated with a metal oxide.

Abstract: The present invention provides improved beverage mix tablets and an improved process for preparing them. According to the improved process, a dipeptide sweetener, acidulent, colorant and hydrophilic material are blended to form a dry mix with which an aqueous moistener comprising glycerine and monocalcium phosphate is admixed to form a cohesive powder. The moistened cohesive powder is then mixed with a disintegrant to form a tabletable mixture which can be suitably compressed to form a coherent tablet which has a tablet density, after drying, of about 0.5 to 1.0 grams per cubic centimeter. The resulting tablet is tough, void-free, nonfriable and rapidly soluble in water.

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.
