Abstract
There is disclosed heme-iron-enriched amino acid preparation consisting of aggregates of heme-protein fragments with heme bonded to histidine groups present in the fragment and a method for preparing this amino acid preparation from heme-proteins, especially hemoglobin. The heme-protein in a manner known per se at first is hemolyzed and denaturated and subsequently split with the aid of proteolytic enzymes to the formation of one heme-iron-enriched and one fraction which does not contain heme-iron and separation of these fractions from each other. The amino acid preparation is suitable for iron enrichment of for instance foodstuffs and for use in pharmaceutical iron preparations.

Heme-iron-enriched amino acid product prepared from heme-proteins, wherein the iron content of the preparation consists solely of the porphyrin iron of the original heme-protein which is bonded as heme to amino acid chains which are shorter than the amino acid chains in the original heme-protein, but which are aggregated into units having larger dimensions than the separate, short, heme-iron-containing amino acid chains.
A process for the preparation of heme-iron-enriched amino acid preparations from heme-proteins, wherein the heme-protein is first hemolyzed and denaturated and subsequently split up with the aid of proteolytic enzymes and forming one heme-iron-enriched fraction and one fraction which does not contain heme-iron and recovering the heme-iron-enriched fraction by separation and stabilizing it by heat treatment and dewatering.
