Q：What is soluble soy polysaccharides? How about its molecular formula, molecular weight and CAS NO.?
A：Soluble soy polysaccharides is extracted from non-GMO soy or soy flake by the process of defatted, extraction, purification, sterilization and drying. It 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. Soluble soy polysaccharides is a kind of soluble polysaccharides and can also be called soluble soy fiber.
Molecular formula:N/A
Molecular weight:The molecular weight of soluble soy polysaccharides ranges from 5000 to 1000000 u,
