Soluble soy polysaccharides is a water-soluble dietary fiber, which is extracted from Non-GMO soybean. Soluble soy polysaccharides can be used in acidified milk drinks and drinking yoghurt. It can provide excellent protein stability and refreshing taste with low viscosity. In addition, soluble soy polysaccharides can also be widely used in carbonated beverages, cocktail, rice and noodles products, disintegrating agent and so on. Thus soluble soy polysaccharides receives increasing attention from global market.

Soluble soy polysaccharides is also called soy polysaccharides, soybean hemicellulose (E426), soluble soy fiber and SSPS in short. Soluble soy polysaccharides is extracted from soy flake by the process of defatted, extraction, purification, sterilization and drying. Below is production flow chart. 

Flow chart of soluble soy polysaccharides

Soluble soy polysaccharides is mainly composed by galactose, arabinose, galacturonic acid, rhamnose, fucose, xylose and glucose. These moleculars are connected by 1,4-glycosidic bonds and 1,6-glycosidic bonds. Its structure is similar to pectin. The molecular weight of soluble soy polysaccharides ranges from 5000-1000000 u.
