PROBLEM TO BE SOLVED: To obtain a heme iron-containing product free from malodor and bad tastes by treating an intermediate of heme iron-containing product with a lipid-dissolving organic solvent. SOLUTION: The degreased heme iron-containing product is produced by using red blood cells of Mammalia, mainly cattle and pig, for example, allowing to homolyse them with a lot of water, centrifuging the heme iron-containing part after inhibiting enzymatic activity with protease, treating the resultant precipitates with a lipid-dissolving organic solvent, filtrating and finally drying the precipitates. As the lipid-dissolving organic solvent, at least one kind selected from methanol, ethagol, n-hexane, acetone, ethyl acetate and dichloromethane is used. By this process, the malodor and the bad taste of theme iron-containing product can be removed and heme iron-containing products, e.g. heme iron- containing foods, which are low in the cost and free from malodor and bad taste are obtained. As the result, the spread on the market becomes easy.
