SSPS Characteristics and Functions
1. Readily Solubility and Excellent Stability for ProteinSoluble soy polysaccharides can be dissolved in both cold and hot water. When formulating 10% solution, there is no gelation. As a stabilizer, it can be used in low pH value acidic milk drinks and drinking yoghurt to hold protein matters and improve stability of product. 2. High Stability and Endurance to Heat, Acid and SaltSoluble soy polysaccharides is rarely affected by heat, acid, salt and can remain great stability. In the range of pH 2-12, soluble soy polysaccharides can present great stability and its viscosity shows good reversibility in this pH range. Even in a strong acid environment (pH 2), soluble soy polysaccharides does not form gelation. This is different from pectin and sodium alginate. When adding different concentration of metal cations, such as NaCl, KCl, CaCl2, to 10% soluble soy polysaccharides water solution, the viscosity of soluble soy polysaccharides does not change substantially. In another words, solub...
