How is alginate made?
Alginate is made of Two uronic acids: d-mannuronic acid (M) and l-guluronic acid (G) extracted from brown algae and kelp [68,69]. The alginate form of alginate is extracted from seaweed under alkaline conditions, then precipitated and ion-exchanged (eg, with potassium).
How do you make alginate?
When soluble calcium salts such as calcium chloride are added to the filtered extract, forming solid calcium alginate. Calcium alginate can form fibers if the calcium solution and filtered extract are carefully mixed – improper mixing will result in a gel-like solid.
