Sodium alginate, a natural polysaccharide, possesses the stability, solubility, viscosity and safety required for excipients of pharmaceutical preparations.It is widely used in food industry as thickener, stabilizer and emulsifier.
1: Used as sizing agent and printing pulp for textiles, and as thickener, stabilizer and emulsifier in food industry
2: as emulsifying stabilizer and thickening agent, it can be used in all kinds of food according to the requirements of production.
3: stabilizer; Thickener; Emulsifier; Dispersant; Gelling agent. By industry, Suspending agent.
4.It is used to increase blood volume and maintain blood pressure, eliminate histamine toxoid produced by burn, maintain blood loss after trauma, stabilize circulatory system before and after operation, large amount of hemorrhagic shock, burneous shock, high fever and acute dysentery, etc., with good therapeutic effect. It also has the effect of excreting cholesterol, inhibiting the absorption of Pb, Cd and Sr by the human body, protecting the gastrointestinal tract, the whole intestine, reducing weight and lowering blood sugar. It is mainly used as suspension aid, emulsifier, thickener and capsule material of microcapsule.
5.Sodium alginate is a kind of high viscosity polymer. It differs from starch, cellulose, etc., in that it has carboxyl groups, which are the aldehyde groups of -D-mannituronic acids formed by glucuronic bonds.
The production process
Sodium alginate process is as follows: dry or wet seaweed (alga) by crushing, water removing impurity, alkali extraction, water clarification, coarse alginate solution by calcium chloride precipitation calcium alginate with color, with acid treatment after decolorizing, flavour, alginic acid precipitation, to remove soluble impurities and sodium carbonate, sodium alginate and drying, crushing, sieving, sodium alginate powder.
