What is Alginate?


Alginate is a natural polysaccharide that comprises from 30 to 60% of brown algae(on dry weight basis). Alginate has dietary fibre properties.

Alginic acid usually accumulates in seaweeds as "jelly bodies" after combining with minerals from seawater. These gel bodies fill the seaweed cells. The litheness of seaweeds growing in the ocean is a result of the flexibility that these jelly bodies, i.e. alginates, provide structure to the seaweed.

Alginic acid was first isolated and named by a Scottish scientist, Dr. E.C.C. Stanford, in1883. Since then, Alginic acid and its derivatives have been utilized as a hydrocolloid in a variety of applications such as food additives, pharmaceuticals, cosmetics and textile manufacturing.
