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 requires strong aqueous base hydrolysis of the lipoproteins to sodium or potassium salts of alpha amino acids mixed with fatty acids. The salts are neutralized to amino acids mixed with fatty acids before the aqueous mixture is reacted with transition metal salts to form aqueous chelates. The aqueous mixture is dried and granulated to form a dry product comprising transition metal chelates homogeneously mixed with fatty acids. The new granular composition containing zinc, iron, manganese, copper, cobalt, or chromium provides a palatable and highly bioavailable source of transition metals for animal nutrition. Effective sources of lipoproteins are fractured cell walls of microbes generated in biological syntheses.
