BILOGICAL PROCEDURE FOR OBTAINING A PREPARED FOOD BASED ON HEMIC IRON AND PREPARED FOOD OBTAINED WITH THIS PROCEDURE.

摘要

Biological procedure for obtaining a food preparation based on hemic iron suitable for the treatment of iron deficiency from the blood of animals, for example pig blood or ox blood, or its derivatives such as the crúor, characterized by succession of the following stages: - a first fraction of animal blood is subjected to a gentle enzymatic hydrolysis performed to obtain a first hydrolyzate containing hemic iron complexed to large peptides as well as non-complexed peptide populations to hemic iron, - enriched the first hydrolyzate thus obtained with hemic iron complexes - peptides by ultrafiltration, to eliminate non-complexed peptide populations to the hemic iron, and to obtain a hydrolyzed solution enriched in hemic iron complexes - peptides, - a second fraction of animal blood is subjected in parallel to an enhanced enzymatic hydrolysis, to obtain r a second hydrolyzate containing hemic iron complexed to small peptides, as well as peptide populations not complexed to hemic iron, - the second hydrolyzate thus obtained is centrifuged in order to eliminate a significant proportion of small peptides not bound to heme, and obtain a centrifuge bottom highly concentrated in heme, - the spin bottom is solubilized, especially by incorporating soda, to obtain an extrinsic solution of heme in which the heme is bound to small peptides, - the solution is mixed of hydrolyzate enriched in hemic iron complexes peptides and the extrinsic heme solution, to allow the fixation of extrinsic heme in the large peptides of the hydrolyzate solution and the release of the small peptides linked to the extrinsic heme, - the mixture thus obtained in order to eliminate extrinsic heme that has not been fixed to the large peptides, and - the solution thus obtained is enriched in hemic iron complexes? peptides by ultrafiltration, to eliminate small peptides released during the mixing step.
