PROBLEM TO BE SOLVED: To provide an insulin secretion promoter, a blood glucose level elevation inhibitor and a production method thereof, capable of lowering production cost and enabling use of unused royal jelly protein.SOLUTION: An insulin secretion promoter and a blood glucose level elevation inhibitor are produced by protease treatment of royal jelly protein with acidic protease, neutral protease or a combination of two or more of them. As royal jelly protein, for example, royal jelly, water-soluble royal jelly protein obtained by extracting water soluble protein from royal jelly, and alcohol denatured royal jelly protein obtained by extracting royal jelly with alcohol can be used. |
