  • Amorphous water-soluble calcium citrate salts and method of making and using same
    Patent number: 7713559
    Abstract: Amorphous water-soluble calcium citrate salts having a mole ratio of calcium to citrate of less than 2.5:2, and powdered beverage mixes and liquid compositions fortified with these amorphous water-soluble calcium citrate salts as a calcium source, are provided. Liquid compositions fortified with calcium citrate according to this invention have superior dispersability, solubility, appearance, and storage stability. These liquid compositions are prepared by new methods that provide and preserve a stable amorphous character in the dry powdered product salts. The present invention also is directed to a method of administering such calcium citrate-fortified liquid compositions to increase the dietary calcium intake in individuals.
    Type: Grant

  • Two-stage method for preparing polyol fatty acid polyesters
    Patent number: 5681948
    Abstract: A two-stage method for the preparation of polyol fatty acid polyesters is provided. The resulting polyol fatty acid polyesters are very lightly colored (i.e., colorless to slightly yellow) and have a high degree of substitution with fatty acid groups. The first stage of this two-stage method is a solvent-based esterification reaction; the second stage is an essentially solvent-free esterification reaction. In the first stage, a polyol in a solvent (e.g., sucrose in dimethylsulfoxide)) is reacted with fatty acid lower alkyl esters at relatively low temperatures using an alkaline salt catalyst. After the desired degree of esterification is obtained, the resulting partially-esterified polyol fatty acid polyesters and the solvent-containing phase are separated.
