Biological process for the production of a food product comprising heme-iron and food product obtained with said process

摘要

Production of a food product from animal blood comprises subjecting a first portion of the blood to controlled enzymatic hydrolysis and concentrating the hydrolyzate by ultrafiltration; subjecting a second portion of the blood to exhaustive enzymatic hydrolysis, centrifuging the hydrolyzate and solubilizing the pellet; mixing the two products and centrifuging the mixture; and concentrating the mixture by ultrafiltration. Production of a food product from animal blood comprises subjecting a first portion of the blood to controlled enzymatic hydrolysis and concentrating the hydrolyzate by ultrafiltration to give a product (P1) rich in iron-complexed high molecular weight peptides; subjecting a second portion of the blood to exhaustive enzymatic hydrolysis, centrifuging the hydrolyzate and solubilizing the pellet, especially by adding sodium hydroxide, to give a product (P2) rich in heme-complexed low molecular weight peptides; mixing P1 and P2 so that heme is bound by the high molecular weight peptides and low molecular weight peptides are released; centrifuging the mixture to remove unbound heme; and concentrating the mixture by ultrafiltration to remove unbound low molecular weight peptides. An independent claim is also included for a food product produced as above, either in the form of a liquid or powder in which the iron/peptide weight ratio is more than 2% and more than 80% of the iron is complexed by peptides, or in the form of capsules filled with a powder as above.
