Sodium alginate is the sodium salt of alginic acid, a natural polysaccharide extracted from brown seaweed (Ascophyllum nodosum, Macrocystis, Laminaria species). It forms gels instantly in the presence of calcium ions, enabling molecular gastronomy techniques like spherification. It is widely used as a thickener, stabilizer, and gelling agent.
Thickens and stabilizes ice cream, salad dressings, and dairy; enables spherification in molecular gastronomy; also used in wound dressings and dental impressions.
Considered safe. No significant adverse effects at food use levels. Functions as a soluble dietary fiber with possible cholesterol-lowering and glucose-moderating effects documented in clinical studies. EFSA confirmed safety with no ADI needed for typical food additive uses.
