HNB Supply Sodium alginate Potassium Alginic acid alginate 99% Powder
CAS 9005-38-3
Sodium alginate is a by-product after extracting iodine and Mannitol from kelp or sargassum of brown algae. Its molecule is composed of β- D-neneneba mannose uronic acid( β- D-mannironic, M) and α- L-neneneba gulose uronic acid( α- L-guluronic (G) is a natural polysaccharide that is connected by the (1 → 4) key and has the stability, solubility, viscosity, and safety required for pharmaceutical excipients. Sodium alginate has been widely used in food industry and medicine field.
The technological process of sodium alginate is as follows: dry or wet seaweeds (algae) are crushed, washed to remove impurities, extracted with strong alkaline water, and clarified to obtain crude Alginic acid salt solution, which is precipitated with calcium chloride to obtain colored Alginic acid, which is treated with acid after decolorization and deodorization to remove soluble impurities to obtain Alginic acid precipitation, which reacts with sodium carbonate to obtain sodium alginate, and then dried, crushed, and screened to obtain sodium alginate powder
