Abstract

An object of the present invention is to provide a dispersion stabilizer for suppressing precipitation and aggregation of a protein under acidic conditions, particularly in a pH range from pH 3.6 to pH 4.4, which is more acidic than near an isoelectric point of the protein and also for providing an acidic protein beverage having low viscosity with a refreshing taste. An acidic polysaccharide having a mass average molecular weight of from 2000000 to 8000000 and containing, as constituent saccharides, 60 wt.% or more of galactose, 20 wt.% or less of uronic acid, and 4 wt.% or more of glucuronic acid, is extracted from lupin beans at a temperature higher than 100°C with pH from 4 to 9 and can stabilize the dispersion of protein particles in wide pH ranges from pH 4.0 to pH 4.4, and from pH 3.6 to pH 4.4 in a case of particularly excellent acidic polysaccharide.
