Addition of a specific sugar compound to an iron-containing protein composition solution can provide an excellent freezing and thawing stability and restrained precipitate productivity in a thawed solution of its frozen product and increase the efficiency in the use of the iron-containing protein useful for enrichment of iron in a food or drink, production of iron preparations.

Iron-containing protein composition

Iron-casein complex hydrolyzate and process for the production thereof

A carbonate- and/or bicarbonate-iron-whey-proteolysate complex includes 1 to 1,000 atoms of iron and one or more molecules of carbonate and/or bicarbonate per one molecule of whey-protein as measured before whey proteolysis, and exhibits no specific iron taste. The carbonate- and/or bicarbonate-iron-whey proteolysate complex is used in drugs, foods, drinks, and animal feed for the purposes of an iron supplement for treatment and prevention of anemia.
