Iron proteinates or chelates of iron with hydrolyzed protein which are usually insoluble are rendered soluble without destroying the chelate and are more readily assimilable by plant and animals.
Claims4
An iron proteinate having a water solubility sufficient to provide an aqueous solution containing at least five precent by weight iron at ambient temperatures at a pH of between about 7 and 8 comprising an iron ion in co-ordination complex with at least three protein hydrolysate ligands selected from the group consisting of polypeptides, peptides and naturally occurring amino acids wherein at least one of the ligands contains an amino group having an excess proton.
