Provided is a method of preparing ferric carboxymaltose with weight average molecular weight between 100,000 and 400,000. The method includes reacting an oxidized maltodextrin solid with an iron (III) salt solution in acidic and basic conditions in sequence to afford ferric carboxymaltose, wherein the oxidized maltodextrin solid has a dextrose equivalent of less than 4. The ferric carboxymaltose prepared by the method can withstand high-temperature sterilization with high stability and facilitate storage.
