PROBLEM TO BE SOLVED: To provide a sericin peptide solution which can be easily and inexpensively produced and which is highly safe, and a method for producing the same. SOLUTION: Ion water is generated by electrolyzing water or an aqueous electrolyte solution in an ion water generation device. The sericin in the cocoon thread is hydrolyzed using the ionized water to obtain a sericin peptide aqueous solution in which the sericin peptide is dissolved in the ionized water. The ionic water used for the hydrolysis may be acidic ionic water or alkaline ionic water. The cocoon is raw silk, It may be a fluff, a cut cocoon, or the like. |
