Sodium Alginate

Alginates are extracts derived from certain Brown Seaweeds (Kelp orĀ Macrocystis). Kelp is commonly found in the northern Atlantic and Pacific Oceans and off the coast of California down through Chile. Alginic Acid exists naturally in the seaweed. Through the extraction and refining process alginic acid is converted to commercially functional Sodium Alginates. Sodium Alginates are used to produce heat-stable gels and to generate viscosity in a variety of fabricated foods, heat-stable fruit fillings, and cheese sauces.

Sodium alginates are soluble in both hot and cold water and are available in a variety of viscosity ranges with various gelling properties. Sodium Alginate solutions are converted, in the presence of calcium ions (calcium chloride or other soluble calcium salt), to Calcium Alginate, the heat-stable gelled form.
