Alginates / Alginic Acid
Algin is a polysaccharide found in brown seaweeds, Phaeophyceae. Of those brown seaweeds, it is the kelp Macrocystis pyrifera that is primarily used in manufacture of Algin. This specie is found mainly in North and South America, Australia, New Zealand, and Africa, and grows in calm waters and in large, dense beds. Other seaweeds used in manufacture of Algin are Ascophyllum nodosum and Laminaria and Ecklonia.
The Algin in the kelp cell wall is a mixed salt (magnesium, calcium, sodium, potassium) of alginic acid. Pure alginates dissolve in distilled water and form smooth solutions. Alginates are compatible with other plant hydrocolloids as well as carbohydrates and proteins.
The uses of Alginates depend on their effective stabilizing, thickening, emulsifying, film forming, water-holding, and gelling properties. There are several grades of sodium, potassium, calcium, ammonium, propylene glycol alginates, and alginic acid available.
