Potassium alginate, a polysaccharide extracted from kelp-like Phaeophyceae; formed by α-L-Mannuronic acid (M section) and β-D-Guluronic acid (G section) connected through 1, 4-glucosidic bond. It’s amorphous powder with white to light yellow color, odorless and tasteless, easily soluble in water forming a viscous solution.
Molecular formula：（C6H7O6 K）n
Thickening: Potassium alginate could be easily dissolved in water and form the solution with high viscosity. It is widely be used as a thickening agent in food ,daily chemical and other industries.
