A powder mix containing soluble pectin which easily dissolves in cold water at about 5° C. is provided. A powder mix including pectin in which the calcium content in pectin has been adjusted to 500 ppm or less is provided. The cold water-solubility of pectin is further enhanced by adjusting the pectin such that 80% by mass or more has a particle size of 150 μm or less, or by dissolving the pectin together with one kind or two or more kinds of sodium salts, potassium salts, and magnesium salts.
