1. Quick Detail :
Alginic acid is a natural polysaccharidc cxtractcd from seaweed. It
is made of the two types of aldehyde acids. Flaxen powder, isn' t
soluble in water.
2. Description :
Alginic acid, 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. The acid is instability state and can react with positive
metal ion to form alginate series production.
Molecular formula : (C6H7NaO6)n
Properties : White or light yellow powder, insoluble in water,
odorless and almost tasteless.
