[Problem] To provide a method for easily and easily producing a solubilized keratin having a high utility value in which coloring and odor generated during hydrolysis of keratin are suppressed. A method for producing solubilized keratin, in which feathers are brought into a water-containing state with a water content of 20 to 80%, and then in an alkaline solution of 0.1 to 0.8 mol / L, 80 to 120 ° C., 0 Production of solubilized keratin having an average molecular weight of 8000 to 13000 (gel filtration method), characterized by hydrolyzing for 1 to 16 hours, then neutralizing the treatment solution, and extracting a keratin degradation product from the supernatant Method.
