Abstract
A method for producing a protein composition containing a protein (A), a radical scavenger (RS), and at least one hydrogen-bond-formable compound (HC) selected from the group consisting of amino acids, peptides, and proteins other than the protein (A). The method including a sterilization step of radiosterilizing an unsterilized protein composition, wherein the unsterilized protein composition contains the protein (A), the radical scavenger (RS), and the hydrogen-bond-formable compound (HC), the protein (A) contains at least one functional group selected from the group consisting of sulfide, amide, hydroxyl, amino, and carboxyl groups, the hydrogen-bond-formable compound (HC) contains at least one functional group selected from the group consisting of sulfide, amide, hydroxyl, amino, and carboxyl groups, the at least one functional group in the protein (A) is capable of binding to the at least one functional group in the hydrogen-bond-formable compound (HC) via a hydrogen bond.
