Abstract:
A method of preparing amino acid transition metal chelates, a palatable highly bioavailable source of transition metals for animal nutrition, from lipoproteins and transition metal salts, the method comprising:(a) admixing a sodium or potassium base with an aqueous lipoprotein, and hydrolyzing the lipoprotein at a temperature between 90 and 180.degree. C. at a pH higher than 9 until aqueous sodium or potassium salts of amino acids and fatty acids are formed;(b) neutralizing the aqueous sodium or potassium salts of amino acids and fatty acids to a pH between 3 and 7; and,(c) reacting water soluble salts of transition metals with the neutralized sodium or potassium salts of amino acids and fatty acids to provide between 1 and 3 molecules of amino acid per transition metal ion, thereby forming an aqueous mixture of amino acid transition metal chelates and fatty acids.
