The above can be selected and used appropriately.

The oil-in-water emulsion of the present invention has a pH of 6.4 to 6.8, preferably 6.4 to 6.7, and more preferably 6.4 to 6.6. If the pH is too low, it tends to feel sour, and if it is too high, the milky taste is poor. Various salts can be used within this pH range. As the salts, it is preferable to use hexametaphosphate, diphosphate, sodium citrate, polyphosphate, sodium bicarbonate or the like alone or in combination. In addition, saccharides, stabilizers, fragrances, coloring agents, preservatives and the like can be used as desired.

The method for producing the oil-in-water emulsion of the present invention can be roughly divided into two cases where the lactic acid fermentation emulsion is mixed in advance with the oil-in-water emulsion and when the lactic acid fermentation emulsion and the oil-in-water emulsion A are mixed.

It is preferable to sterilize from the viewpoint of storage stability of the oil-in-water emulsion. Specifically, various raw materials are pre-emulsified at 60 to 70 ° C. for 20 minutes (the emulsifier is a homomixer) and then homogenized under the conditions of 0 to 25 MPa as necessary (the emulsifier is a homogenizer). Next, after ultra-high temperature instant sterilization (UHT), it is homogenized again under the condition of 0 to 30 MPa, and after cooling, it is aged for about 24 hours.

When mixing the lactic acid fermentation emulsion and the oil-in-water emulsion A, the oil-in-water emulsion A is other than the lactic acid fermentation emulsion in the method for producing an oil-in-water emulsion described in paragraph [0025]. Can be obtained in the same manner and in the same manner.
Although the lactic acid fermentation emulsion and the oil-in-water emulsion A are mixed, the oil-in-water emulsion A may be homogenized and in the middle of cooling or after cooling.
