Sodium Alginate, E401, CAS no.9005-38-3, food thickener, manufacturing process from brown seaweeds. Sodium alginates are soluble in both hot and cold water and are available in a variety of viscosity ranges with various gelling properties. Sodium Alginate solutions are converted, in the presence of calcium ions (calcium chloride or other soluble calcium salt), to Calcium Alginate, the heat-stable gelled form.
As an experienced Sodium Alginate manufacturer and supplier, we has been supplying and exporting Sodium Alginate: Super low viscosity (10-100cps), Low viscosity (100-200cps), Middle viscosity (200-500 cps), High viscosity (500-1000 cps), Super high viscosity (above 1000 cps) for almost 10 years, please be assured to buy from us. Any inquiries about price and the market trend please feel free to contact us, we will reply you within 1 working day.

Sodium alginate is a natural polymer derived from brown seaweed, known for its remarkable thickening, gelling, and stabilizing properties. Widely employed in the food industry, sodium alginate is utilized to create gels and provide texture in various culinary applications, such as in the formation of gel-like spheres through molecular gastronomy techniques. It also finds use in the pharmaceutical and textile industries, where it serves as a thickener in liquid medicines and a sizing agent in textile printing, respectively. Sodium alginate's biocompatibility and ability to form gels in the presence of calcium ions make it a versatile and valuable substance in numerous fields.

Sodium Alignate powder is a kind of natural polysaccharide which exists in kelp, macroalgae and other brown algae. It is a natural product formed by alginic acid in algae and minerals in seawater, alginic acid is a kind of mixed polysaccharide, which is composed of mannose uronic acid (m) and guloronic acid (g) . Widely used alginate products are sodium alginate, potassium alginate, calcium alginate, ammonium alginate and so on.
