FUNCTIONAL CHARACTERISTICS
Alginate is a kind of natural polysaccharide consisted in brown seaweed, as a natural product generated from alginic acid indwell in seaweed and minerals indwell in sea. Alginic acid is a mix-polysaccharide composed of D-mannuronic acid(M) L-guluronic acid(G). The main alginate series include sodium alginate, potassium alginate, calcium alginate, ammonium alginate etc.
Chemical structure
Solution properties
As the hydrophilic gel, sodium alginate is the prevailing salt of align, which is apt to form thick solutions. with the properties of thickness and stability, sodium alginate can be used as thickener and stabilizer in foodstuff and printing paste, oil-extraction agent etc.
Uses
