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.
