The invention discloses a blood
protein polypeptide rich in
heme iron and a preparation method thereof, and belongs to the technical field of blood
protein polypeptides, the blood
protein polypeptide contains
heme iron, and is obtained by firstly adding an
anticoagulant into animal fresh blood, then centrifuging, discarding
plasma, collecting red blood cells, breaking walls, heating, performing enzymolysis, performing
ultrafiltration, concentrating and
drying. The blood protein polypeptide is rich in
heme iron, can be directly absorbed by
intestinal mucosa cells compared with a traditional iron supplementing agent, and does not easily generate any
digestive tract stimulation symptom; during preparation, a high-pressure
homogenizer is adopted, so that the efficiency is improved, and the
protein content is increased; and further heating for 30 minutes at 50 DEG C under a dark condition to remove denatured impure proteins, so that the content of
hemoglobin is up to 90% or above. While the
peptide is generated, the
heme iron is not completely separated from the protection of the
peptide and is continuously kept in a
divalent water-soluble state. The
gastrointestinal tract discomfort phenomena such as
nausea and
vomiting after the conventional
iron agent product is taken are avoided, and the trouble of
anemia people is solved.
