PURPOSE:To efficiently produce a desired emulsion enhanced in emulsifying ability without decomposing protein by mixing an oil with a protein in a strong alkaline condition to prepare a raw material dispersed solution and returning the solution to a neutral region. CONSTITUTION:The raw material dispersed solution 4 of an intermediate product having the strong alkalinity of >=PH10 is prepared by using an oil 1 and a protein 2. The raw material dispersed solution 4 is an emulsion made by uniformly dispersing a fine oil drop of a dispersed phase in water as a continuous phase. Next, the raw material dispersed solution 4 is made to a neutral region and is stabilized to obtain the desired emulsion 6. In this case, it is preferable to prepare the raw material dispersed solution at a low temp. and to made to the neutral region as quickly as possible because denaturalization reaction of the raw material dispersed solution is slow at low temp. near 0 deg.C. |
