PROBLEM TO BE SOLVED: To provide a method for conveniently manufacturing a stable oil-in-water emulsion from a water-insoluble flavoring agent and silicone. SOLUTION: A method for preparing an oil-in-water emulsion includes the steps of adding (b) a water-insoluble flavoring agent to (a) silicone in amounts of (b)/(a)=0.1 to 1.5 (mass ratio) and uniformly mixing the resulting product, adding (c) a nonionic property surfactant to the obtained mixed solution in amounts of (c)/(a)=0.1 to 2.0 (mass ratio) and uniformly mixing the resulting product, adding (d) water to the obtained mixed solution in amounts of (d)/(a)=1 to 5 (mass ratio) and mixing the resulting product, and adding (e) water and/or a separately prepared oil-in-water emulsion to the obtained mixed solution and mixing the resulting product to cause phase inversion to form an oil-in-water emulsion.
