Soluble soybean polysaccharide

Soluble soybean polysaccharide (SSPS) is a water-soluble polysaccharide extracted from soybean. SSPS consists mainly of the dietary fiber of the soybean cotyledon and has relatively low viscosity and high stability in an aqueous solution. SSPS has various functions such as dispersion, stabilization, emulsification, and adhesion. Therefore, it can be used not only as a dietary raw material for fiber-fortified foods, but also for pharmaceutical and industrial applications as well as for many other food applications. In this chapter, we describe the chemical structure, properties, and applications of SSPS as a functional food ingredient.
