Sodium Alginate is a premium natural polysaccharide derived from the extraction of brown algae and Sargassum. Composed of β-D-mannuronic (M) and α-L-guluronic (G) acid units connected by (1→4) linkages, it serves as a high-performance hydrophilic colloid. Its exceptional stability, solubility, and viscosity make it an indispensable excipient for pharmaceutical preparations and a versatile additive for the global food industry.
Known for its unique ability to form thermally irreversible gels when encountering calcium ions, Sodium Alginate allows for precise control over material hardness and flexibility by adjusting the M/G ratios. Whether utilized as a thickener in beverages, a stabilizer in food processing, or a key component in bionic materials and wastewater treatment, our food-grade and medical-grade offerings ensure superior quality and safety for diverse industrial applications.

Frequently Asked Questions
High-G alginate produces a harder but more brittle gel, while High-M alginate produces a more flexible gel with lower hardness. By adjusting these ratios, we can create a wide variety of textures for bionic foods and materials.
Yes, due to its natural stability, safety, and solubility, Sodium Alginate is widely used as an excipient in medical-grade pharmaceutical preparations.
As a hydrophilic colloid, it dissolves in water to form a viscous solution, providing essential thickening and stabilizing properties for beverages and processed foods.
Our Sodium Alginate is packaged in 25kg bags and is suitable for transportation via ocean or land, provided it is kept in a cool, dry environment.
No, when alginate encounters calcium ions, it forms a gel that is thermally irreversible, meaning it will not melt upon heating.
Beyond food and medicine, it is used in printing pastes, oil additives, wastewater treatment agents, cling films, and cosmetic masks.
