The invention relates to new protein derivatives of blood, blood-protein containing raw materials and hemoglobin, and more particularly to processed globin products, and to processes for producing these products. These processed globin products have an iso-electric point at a pH value below 5,5, in particular at a pH value in the range from 3 to 5,5, preferably between 4 and 5; an iron content of less than 1000 ppm; a ratio of His : Lys between 0,6 and 1,5; a Tyrosine content of at least 0,5 % by weight; a Methionine content of at least 0,5 % by weight; a Lysine content of at least 5 % by weight. The method for the production of these processed globin products comprises treating the starting material at a pH above 12 and an oxidizing treatment at a pH below 12, while maintaining the temperature below 50 DEG C. |
