A composition and method of preparing amino acid chelates and complexes free of interfering ions by blending an amino acid ligand, a calcium oxide and/or hydroxide, and a hydrated metal sulfate salt, placing the blend in a closed environment, heating the blend, and allowing the blend to react is disclosed and described. By heating at low to moderate temperatures in an enclosed environment, the waters of hydration of the metal salt are retained in the enclosed environment and serve to provide the moisture necessary to enable a bonding reaction to take place between the electron rich functional groups of the ligand and the metal ion of the hydrated metal sulfate salt. Additionally, calcium sulfate is formed which can be maintained in the final product.

Composition and method for preparing amino acid chelates and complexes free of interfering complex ions

Compositions and methods of preparing amino acid chelates and complexes are disclosed and described. Specifically, by (a) combining a hydrated metal sulfate salt with an amino acid ligand to form a particulate blend, (b) placing the particulate blend in an enclosed environment; and (c) applying heat to the particulate blend in the enclosed environment causing the waters of hydration of the metal sulfate salt to be released into the enclosed environment causing a reaction resulting in the formation of an amino acid chelate or complex by effecting the reaction between functional electron rich groups of the amino acid ligand and a metal ion of the metal sulfate salt. The waters of hydration serve to provide the water necessary to enable a bonding reaction to take place between the electron rich functional groups of the amino acid ligand and the metal ion of the hydrated metal sulfate salt.

Composition and method for preparing amino acid chelates and complexes

The present invention relates to compositions and methods of preparing amino acid chelates that are essentially free of interfering ions. The composition is prepared by reacting in an aqueous solution, a calcium oxide and/or hydroxide, an amino acid, and a soluble metal sulfate salt at a ratio sufficient to allow substantially all of the ions present in solution to react forming a positively charged metal amino acid chelate having a hydroxide counter-ion, and calcium sulfate, and wherein the metal amino acid chelate has a ligand to metal molar ratio from 1:1 to 2:1.

Composition and method for preparing amino acid chelate hydroxides free of interfering ions

Compositions and methods of preparing amino acid chelates and complexes are disclosed and described. Specifically, by (a) blending hydrated metal sulfate salts, amino acid ligands, and reaction modifiers; (b) confining the particulate blend in an enclosed environment; and (c) applying heat to the particulate blend in the enclosed environment causing the waters of hydration of the metal sulfate salt to be released into the enclosed environment causing a reaction resulting in the formation of a granular amino acid chelate or complex by effecting the reaction between functional electron rich groups of the amino acid ligand and a metal ion of the metal sulfate salt. The waters of hydration serve to provide the water necessary to enable a bonding reaction to take place between the electron rich functional groups of the amino acid ligand and the metal ion of the hydrated metal sulfate salt.

Composition and method for preparing granular amino acid chelates and complexes

The present invention relates to compositions and methods of preparing amino acid chelates that are electrically neutral and free of interfering ions. The composition is prepared by reacting in an aqueous solution a calcium oxide and/or hydroxide, an amino acid, and a soluble metal sulfate salt at a ratio sufficient to allow substantially all of the ions present in solution to react forming a metal amino acid chelate and an essentially inert calcium sulfate, and wherein the metal amino acid chelate has a ligand to metal molar ratio from 2:1 to 3:1.

Composition and method for preparing electrically neutral amino acid chelates free of interfering ions

Calcium amino acid chelate complexes for fortification of dairy products and oleaginous foods, dairy products and oleaginous foods fortified with calcium amino acid chelate complexes, and methods of preparing calcium amino acid chelate complexes are disclosed and described. The calcium amino acid chelate complexes of the present invention are stable, palatable, and bioavailable. Preparation steps include reacting a calcium compound, an amino acid ligand, a pH adjuster, and, optionally, a stabilizing/suspending agent in an aqueous environment.

Compositions and methods for calcium fortification of dairy products and oleaginous foods

A palatable metal amino acid chelate for administration to humans and other warm-blooded animals is disclosed wherein there are sufficient ligands to provide ionic and coordinate covalent bonds equal to the coordination number of the central metal ion while, at the same time, maintaining charge balance in the chelate molecule. There must be at least one ligand of the polydentate type which must be an .alpha.-amino acid with the further proviso that any unidentate or polydentate ligand(s) must be charge balanced organic ligands. Charge balancing may be accomplished by means of an organic acid and dicarboxylic, hydroxycarboxylic, hydroxydicarboxylic or hydroxytricarboxylic acids in particular, which maintains the chelate molecule as an optimum pH for purposes of stability and palatability.
