  • Calcium enrichment composition and method for producing the same
    Patent number: 6599544
    Abstract: An improved calcium-enriched composition and method of supplementing food products with the composition are provided. Broadly, the compositions include respective sources of phosphate ions, citrate ions, and calcium ions, metal hydroxides, and water, with the molar ratio of citrate ions to phosphate ions in the composition being from about 1.0:1.35 to about 1.0:2.35. The compositions have high solids contents relative to prior art compositions, and at least about 70% of the theoretically available calcium ions remain dispersed in the compositions at ambient temperatures. The compositions are in the form of a colloidal suspension having very little or no sedimentation. Finally, the compositions can be mixed with food products (e.g., cow's milk, soy milk) to substantially increase the calcium available in the product without negatively affecting the taste, color, or smell of the product.
    Type: Grant

    Date of Patent: July 29, 2003
    Assignee: American Micronutrients, Inc.
