Abstract

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.
