The invention relates to a method for producing a clear beverage comprising the steps of: (i) providing an oil-in-water (O/W) emulsion comprising an n-alkenyl succinate starch and an essential oil, wherein the n-alkenyl succinate starch is in excess of said essential oil; (ii) producing a turbid beverage by diluting said O/W emulsion to reach a desired beverage concentration; and (iii) storing said turbid beverage at a temperature of above 30 C. for a time sufficient to obtain a clear beverage.

An object of the present invention is to provide a technique of suppressing precipitation of an anthocyanin pigment in a range other than the highly acidic range.

The present invention provides an anthocyanin pigment preparation, comprising: an anthocyanin pigment; and an emulsifier, wherein the pH when the anthocyanin pigment preparation is diluted with water or dissolved in water so that a color value becomes 10 is more than 3.
