Alginic acid is a natural polysaccharide extracted from seaweed, formed by α - L - Mannuronic acid (M section) and β - D - Guluronic acid(G section) connected through 1,4-glucosidic bond.The acid is instability state and can react with positive metal ion to form alginate series production.
Molecular formula: (C6H8O6) n
Property:
White or light yellow powder, insoluble in water.odorless and almost tasteless.
Application:
1. Medicine: The main raw materials of the Gaviscon tablets,tablets disintegration agent and hypotensor element.
2. Food: It can combine with a variety of ions into alginate products and used in the production of health food.
Package:
25kg(net weight) per bag,with compound package bag(a polyethylene bag as liner and a compound plastic woven bag as the outer layer).
