Sodium alginate

Sodium alginate is a by-product of the extraction of iodine and mannitol from the kelp of the brown algae or Sargassum, the molecules of which are β-D-mannuronic (M) and α-L-gulo Glucuronic acid (α-L-guluronic, G) is formed by connecting (1→4) linkages and is a natural polysaccharide with the stability, solubility, viscosity, and safety required for excipients for pharmaceutical preparations. Alginate has been widely used in food industry and medicine.

Sodium alginate specification:

Viscosity （mPa.s）	500-700
Mesh	80 mesh
Moisture	15 % Max
PH	6.0-8.0
Water-insoluble in water	0.6% Max
Pb (mg/kg)	5.0 Max
As (mg/kg)	2.0% Max
appearance	White or light yellow powder

Sodium alginate as a hydrophilic colloid, is easily soluble in water to form a viscous solution. With its thickening stability, it can be used as a food and beverage thickener, stabilizer, printing paste, oil additives.
3. The waste liquid from the grass pulping process is used as raw material. Method 2

Synonyms :SA
CAS no:9005-38-3
Molecular formula:(C6H7NaO6)x

Molecular weight:M=398.31668

When alginate encounters calcium ions, ion exchange occurs rapidly and a gel is formed. The gel is thermally irreversible. The gel formed by the high-G alginate has a large hardness but is brittle; the gel produced by the high-M alginate is the opposite, but has good flexibility but low hardness. Adjusting the two ratios produces different strength gels. Using the gel properties, it can be used to make a variety of bionic foods, materials, masks, waste water treatment agents, cling film and so on.
