ABSTRACT:
A two-stage method of preparing essentially pure amino acid chelates, wherein the first stage comprises contacting a metal ion from a metal oxide or hydroxide with an amino acid thereby producing a metal hydroxyl amino acetate. The second stage comprises contacting the metal hydroxyl amino acetate from the first stage, with at least one amino-containing compound provided in excess thereby producing a reaction solution containing an amino acid chelate reaction product comprising a metal ion bound to a plurality of amino acid ligands wherein the plurality of amino acid ligands is equal to the coordination number of the metal ion, and then separating the amino acid chelate from the reaction solution. The second stage may include a plurality of steps for sequentially reacting the reaction product with a plurality of amino-containing compounds. The amino acid chelates thus produced can be incorporated into compositions comprising beverages, foodstuffs, nutraceuticals and pharmaceutical adjuvants.
