A decolorized blood product and method for making the product is provided. Broadly, the products are formed by mixing a low concentration of an oxidant with a starting composition comprising a blood component such as red blood cells without subjecting the composition to a pH reversal. Just prior to the mixing step, the starting composition is preferably heated to a temperature of from about 50-80 ~C so as to inactivate the peroxidase enzymes in the composition. The resulting products are light in color, have a mild flavor, and retain a high yield of the protein, and iron of the starting compositions. Furthermore, the products formed by this method do not contain undesirable by- products such as free heme or excess oxidant.

L'invention concerne un produit sanguin décoloré et son procédé de fabrication. Les produits sont généralement fabriqués par le mélange d'une faible concentration d'oxydant et d'une composition de départ comprenant un composant sanguin, tel que des globules rouges, sans que la composition subisse une inversion de pH. Juste avant l'étape de mélange, la composition de départ est de préférence portée à une température comprise entre environ 50 et 80 ·C, de sorte que les peroxydases contenues dans la composition soient inactivées. Les produits résultants présentent une couleur claire, sont doux au goût et conservent une grande quantité de protéines et de fer de la composition de départ. Par ailleurs, les produits formés par le procédé de l'invention ne contiennent pas de sous-produits indésirables, tels que l'hème libre ou un excédent d'oxydant.
