Possible Production (Sodium Alginate): The possible production of sodium alginate is the amount of the sodium salt of alginic acid extracted from the naturally grown brown algae collected from the selected region of the seashore.
The alginate is usually found in the seaweed cell walls, as calcium, magnesium, sodium and potassium salts, derived from the interaction between alginic acid and alkaline or alkaline earth elements found in seawater (ANTUNES et al.
