Calcium Alginate , pharmaceutical calcium alginate
Molecular formula : [(C 6 H 7 O 6 ) 2 Ca] n
Properties : White to yellowish powder, odorless and tasteless, insoluble in water.
Uses: Often used in food industry,welding electrode,plastifier and wet
state binder. Calcium Alginate is a natural carbohydrate extracted from kelp.It can also be used on health food industry as a Calcium additive
Calcium Alginate is a new product that we developed. Its quality reached the domestic advanced standard in this field.
Preparation of Calcium alginate:
The goal of the extraction process is to obtain dry, powdered, sodium alginate. The calcium and magnesium salts do not dissolve in water; the sodium salt does. The rationale behind the extraction of alginate from the seaweed is to convert all the alginate salts to the sodium salt, dissolve this in water, and remove the seaweed residue by filtration. The alginate must then be recovered from the aqueous solution. The solution is very dilute and evaporation of the water is not economic. To the Sodium alginate from the initial extraction solution, a calcium salt is added. This causes calcium alginate to form with a fibrous texture; it does not dissolve in water and can be separated from it.
