Sodium alginate powder Raw Materials CAS 9005-38-3 Details
Uses and synthesis of Sodium alginate powder
- Sodium alginate Raw Materials Also known as sodium alginate, sodium fucoidan, sodium alginate, brown algae gum, kelp gum, sodium alginate, Sodium alginate, Sodium alginate powder is the sodium salt of alginate, a mixture of polyglycolic acid. It is a kind of gum extracted from brown seaweed such as kelp;
- Sodium alginate CAS 9005-38-3 (CHONa) mainly consists of sodium salt of alginate, is a polysaccharide biopolymers, with a wide range of sources, non-toxic, easy to degrade, easy to biocompatibility and other characteristics, so Sodium alginate CAS 9005-38-3 has great application value in various industries such as pharmaceuticals, food, packaging, textile industry, biomaterials and so on. Therefore, Sodium alginate CAS 9005-38-3 has great application value in pharmaceutical, food, packaging, textile industry, biological material and other industries.
- Sodium alginate powder is white or light yellow powder, odorless, tasteless, moisture-absorbent, relative density 1.59, bulk density 87.39kg/m3, moisture content 13%, ash 23%, blackening temperature 150℃, carbonization temperature 340℃(460℃), ashing temperature 480℃, heat of combustion 10.46J/g, insoluble in ethanol, ether or chloroform, ethanol, ether or chloroform, etc.
Sodium alginate powder is soluble in hot water and cold water, 1% aqueous solution pH value of 6 ~ 8, can form a viscous colloidal solution, and easy to mix with proteins, starch, pectin, gum arabic, carboxymethylcellulose, sucrose, propanetriol and sorbitol. Insoluble in dilute acid with pH less than 3. When the pH is 6~9, Sodium alginate Raw Materials viscosity is stable, and its viscosity decreases when heated above 80℃.
Applications / Functions of Sodium alginate powder
- Sodium alginate Raw Materials used as textile sizing agent and printing paste, at the same time as a thickener, stabilizer, emulsifier used in large quantities in the food industry.
- Sodium alginate powder used as emulsifying stabilizer and thickener, China's regulations can be used for all kinds of food, according to the production needs of the appropriate amount of use.
- Sodium alginate CAS 9005-38-3 is used to increase blood volume and maintain blood pressure, exclude histamine toxin produced by burns and trauma blood loss, circulatory system stabilization before and after surgery, massive hemorrhagic shock, burn shock, high fever and acute dysentery and other systemic dehydration, the therapeutic effect is good.
Sodium alginate CAS 9005-38-3 also has the effect of making cholesterol excreted from the body, inhibiting the absorption of Pb, Cd, Sr into the human body and protecting the gastrointestinal tract, rectification of intestines, weight loss and lowering of blood glucose.Sodium alginate powder is mainly used as a suspending agent, emulsifying agent, viscosifying agent, and the capsule material of microcapsule in the pharmaceutical industry.
Physicochemical Property of Sodium alginate powder
Colorless or light yellow filamentous granule or powder solid. Sodium alginate Raw Materials is insoluble in organic solvents such as ethanol, ether and chloroform.
Sodium alginate powder is hygroscopic. The aqueous solution of sodium alginate is stable at pH 4-10, precipitation occurs at pH <3; hydrolysis occurs at pH >10, and viscosity is lost; metal containers cannot store sodium alginate solution. The solution is susceptible to microorganisms during storage, changing its viscosity.
The concentration of the solution decreases when it is heated above 70°C; hot-pressure sterilization can reduce the viscosity of the solution; γ-ray sterilization also reduces the viscosity of the solution. Preservatives should be added to topical preparations for preservation. Bulk substances should be stored in airtight containers in a cool, dry place.
Production methodprocess of Sodium alginate powder
The kelp after iodine extraction is stirred and soaked in sodium carbonate solution for 2h at 60~80℃, the extracted liquid is roughly filtered through 0.54mm sieve cloth, and then the kelp residue is removed by emulsification floatation method, and then the clear liquid is finely filtered through 0.147mm sieve cloth.
The pH was adjusted to 2 with hydrochloric acid, the alginate gel was precipitated, and 5% calcium chloride was added to dehydrate the gel. After pressure filtration, the water content of the gel was below 75%, and 6%-8% sodium carbonate solution was added to make the gel alkaline, and it was dried after standing for 8h to obtain Sodium alginate Raw Materials .
