Abstract: There is provided an acidic vegetable protein beverage containing a legumes-derived water-soluble polysaccharide, a divalent cation, and a vegetable protein. There is also provided a protein dispersion stabilizer for an acidic vegetable protein beverage, containing a legumes-derived water-soluble polysaccharide and a divalent cation. There is further provided a production method of an acidic vegetable protein beverage, including adding a legumes-derived water-soluble polysaccharide and a divalent cation.

Abstract: An object of the present invention is to provide a method for producing an untangling-improving agent for inhibiting quality deterioration such as a difficulty in untangling after storage and efficiently producing tasty noodles, and to provide noodles prepared by using the untangling-improving agent. The untangling properties of noodles can be improved, and at the same time, the elasticity and chewiness of noodles can be maintained by adding, to noodles, an untangling-improving agent for noodles obtained by incorporating monoglycerol fatty acid ester and protein, wherein the monoglycerol fatty acid ester and protein are in the emulsified state.

Abstract: [Problem] To provide: a water-insoluble plant fibrous material derived from soybeans that has both the functions of imparting viscosity to liquid batter and of stabilizing viscosity; a method for imparting viscosity to liquid batter using said raw material; and a method for stabilizing viscosity. [Solution] The provision of an agent for imparting viscosity to liquid batter was achieved by using a water-insoluble plant fibrous raw material obtained by: heating a slurry, prepared by adding water to bean curd lees, to more than 100° C. and up to 150° C.; then substantially removing the water-soluble component thereof.

Abstract: Disclosed is a novel water-soluble soybean polysaccharide which is produced by imparting a function of stabilizing a protein in a pH range around the isoelectric point of the protein to a water-soluble soybean polysaccharide. Also disclosed is a novel dispersion stabilizer which enables to stabilize the dispersion of a protein in a pH range around the isoelectric point of the protein. Further, disclosed is a acidic protein food/beverage comprising the dispersion stabilizer. A crosslinked product of a water-soluble soybean polysaccharide extracted from a soybean seed raw material can improve the dispersion stability of a milk protein in a pH range around the isoelectric point of the protein. By using the water-soluble soybean polysaccharide, an acidic protein food/beverage having a low viscosity can be produced.
