Description

General description

Sodium alginate is the sodium salt of alginic acid, a natural polysaccharide found in brown algae. It is generally used as a stabilizer and thickener in the food industry. Sodium alginate may undergo cross-linking in the presence of divalent cations such as Ca2+ to form biodegradable stable gels, which finds applications as a material for cell encapsulation and immobilization.

Packaging

1 kg in poly bottle

5 kg in poly drum

Other Notes

A straight-chain, hydrophilic, colloidal, polyuronic acid composed of glucuronic and mannuronic acid residues.
