Abstract: This invention relates to a method of separating globin comprising separating hemoglobin from blood of an edible animal, forming an aqueous solution containing 0.5 to 5% of hemoglobin, adding an acid to the aqueous solution to adjust the pH value to 2.0 to 2.2 and the ionic strength to 0.005 to 0.015, bringing the aqueous solution into contact with carboxymethyl cellulose equilibrated with an acidic liquid having a pH value of 2.0 to 2.2 and an ionic strength of 0.005 to 0.015 and then dissolving out globin from the carboxymethyl cellulose with an acidic liquid. The so-obtained dry product of globin is substantially free of haem and it has been found that this dry product is suitable as a protein material for use in processing of foods.
