Sodium Alginate

Your reliable sodium alginate supplier!!!

What Is Sodium Alginate

Sodium Alginate (E401 stabilizer) is derived from various species of brown seaweed found off the coasts of the North Atlantic, South America and Asia. It's used for thickening, stabilising, gelling and film-forming purposes,  honored to be the exciting hydrocolloids widely explored by scientific groups.

As the sodium alginate supplier and exporter in China, Gino is dedicated to supplying superior alginate products from reliable sodium alginate manufacturer. Meanwhile, we can offer tailor-made solutions perfectly matched to your needs.

Sodium Alginate Formula

Sodium alginate is the sodium salt of alginic acid. Its chemical formula is (C6H7NaO6)n.

Sodium Alginate Structure

Sodium Alginate Structure_Chemical Structure Depiction

Sodium Alginate Gel

The gel forms by chemical reaction, the calcium displaces the sodium from the alginate, holds the long alginate molecules together and a gel is the result. No heat is required and the gels do not melt when heated. This is in contrast to the agar gels where the water must be heated to about 80°C to dissolve the agar and the gel forms when cooled below about 40°C.

Sodium Alginate Properties

It provides a unique combination of properties including cold solubility, cold-setting gels, non-melting gels (heat/temperature independent) and freeze-thaw stable gels.

Temperature (gels and melts): not affected by temperature. Gel is heat stable up to 150 °C (302 °F) but prolonged heat treatment at low or high PH may destabilize the gel.

Texture: Thermo irreversible rigid and brittle gel in the presence of calcium. The higher the concentration of alginate and calcium, the harder the gel produced.

Appearance: clear and transparent.

Flavor release: as most hard set gels, poor flavor release.

Mouthfeel: lingering and sticky.

Freeze / Thaw stable: yes, in most applications.

Syneresis (weeping): yes, increases with gel strength.

Shearing: breaks gel.

Is Sodium Alginate Safe

Is sodium alginate safe? Is sodium alginate safe to eat? Is sodium alginate edible?

Yes, it has been approved safe by the U.S. Food and Drug Administration (FDA) and European Food Safety Authority (EFSA), as well as the Joint FAO/WHO Expert Committee on Food Additives (JECFA). 

Sodium Alginate Benefits

Sodium alginate is a non-digestible carbohydrate and the FDA intends to propose it in the list of dietary fibers. It has the benefits of lowering blood sugar, blood pressure, cholesterol levels and other health effects.

Sodium Alginate Applications

What is Sodium Alginate Used for?

Alginic acid is used as a hydrocolloid in various applications such as food manufacturing, pharmaceuticals and in textiles and cosmetics, particularly as an emulsifier, and is also used in dentistry to make molds. More recently, alginate have been studied extensively due to its tissue compatibility and use in tissue engineering, including the regeneration of skin tissue, cartilage, bone, pancreas, liver, muscles and nerves (Lee and Mooney, 2012), in addition to being used in the encapsulation of cells for the controlled release of drugs.

Sodium Alginate in Food:

In food applications, alginates provide texturizing properties such as thickening, stabilizing, and gelling.
