Process for preparing decolorized blood proteins.

摘要

Whole blood, or the cruor obtained therefrom after separation of the plasma, is subjected to a haemolysis and then to a controlled enzymatic digestion, which has the effect of rendering the red haemoglobin pigment more accessible to oxidising agents in an aqueous medium. The pigment can then be decolorised by oxidation under mild conditions, the mixture resulting from this oxidation then being treated to separate from it solids containing assimilable iron, in the form of a dry powder. This powder is advantageously used in human nutrition.
