PROBLEM TO BE SOLVED: To improve the dispersion stability of casein particles in an acidic milk drink by adding a carboxymethylcellulose sodium salt (CMC) having stable quality. SOLUTION: A stabilizer, composed of a CMC having a viscosity of 10-500(mPa.s) in a 1wt.% aqueous solution, an average substitution degree of 0.6-1.2 and the number of unsubstituted glucose units of 10-65 based on 1000 glucose anhydride units, is added to an acidic milk drink to highly stabilize the dispersion of casein particles. The mobility distribution (▵U) of the CMS determined by electrophoresis is <=5.5×10<-5> (cm<2> /V.s). |
