Abstract: The invention is directed to a method for producing acidic milk beverages, characterized by homogenizing fermented milk, then adding water-soluble hemicellulose thereto for mixing, followed by an additional step of homogenization. The method provides stable acidic milk beverages which undergo less sedimentation or separation of whey during product storage, and which have favorable flavor.

Abstract: A cultured milk beverage contains at least 3.times.10.sup.8 cells/ml of at least one type of lactic acid bacterium selected from the group consisting of Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus helveticus and Lactobacillus jugurti and a mixture of a galactooligosaccharide, which is represented by the following formula:Gal-(Gal).sub.n -Glcwherein Gal means a galactose residual group, Glc denotes a glucose residual group, and n stands for an integer of 1-4, and a galactosyldisaccharide represented by the following formula:Gal-Rwherein R means a galactose residual group or a glucose residual group, and Gal has the same meaning as defined above, said galactosyldisaccharide being other than lactose. The cultured milk beverage can be produced providing the lactic acid bacterium and culturing the same to a population of at least 3.times.10.sup.
