Technical Document

Sodium Alginate Sodium alginate is a natural anionic polysaccharide made from brown seaweed (Laminaria, Ascophyllum) via alkaline digestion and precipitation, providing cold-soluble gelation with calcium ions forming "egg-box" junctions, superior heat stability (>180°C), and shear-thinning rheology as primary thickener/stabilizer at low dosage (0.1-1%). In the food industry, it delivers precise texture control, brine resistance, and clean mouthfeel ideal for restructured foods, beverages, sauces, and molecular gastronomy.
