摘要： An object of the present invention is to provide a method for advantageously producing a protein molded article which can solve a problem caused by esterification of a hydroxyl group contained in a protein while maintaining a sufficient strength. A method for producing a protein molded article according to the present invention includes a step of bringing a raw material molded article containing a protein in which a hydroxyl group is esterified into contact with an acidic or basic medium in a state of applying a tensile force, thus hydrolyzing an ester group.
