Frequently Asked Questions
What is the primary use of Sodium Alginate?
The primary industrial and food-grade use of Sodium Alginate is as a highly efficient thickener, gelling agent, stabilizer, and film-forming agent. It is widely used in textile printing paste, food production (like ice creams, yogurt, and molecular gastronomy spherification), and as a key active ingredient in pharmaceutical formulations.
What is the molecular weight and chemical formula of Sodium Alginate?
Sodium Alginate is a natural hydrophilic polysaccharide polymer. The chemical formula for its repeating structural monomer unit is (C6H7NaO6)n. The molecular weight of a single repeating monomer unit is approximately 198.11 g/mol, while the overall macromolecular chain weight ranges dynamically based on extraction source and processing.
How is Sodium Alginate powder used with Sodium Bicarbonate and Calcium Carbonate?
In medicine, sodium alginate powder is blended with sodium bicarbonate and calcium carbonate to form a highly effective anti-reflux oral suspension. When this combination reacts with stomach hydrochloric acid, it triggers rapid sodium alginate raft formation. This creates a strong, neutral physical gel barrier that floats on top of the gastric contents, making it an excellent recipe for reflux, GERD, and heartburn management.
What are the core applications of Sodium Alginate syrup and its uses?
Sodium alginate syrup uses are predominantly therapeutic. It acts as a specialized antacid coating that physically blocks acid from traveling back up into the esophagus. Because of its safety profile and mechanical action, it is frequently searched by healthcare providers under terms like sodium alginate uses in to educate patients on managing acid reflux.
How is Sodium Alginate prepared for bead formation or spherification?
For sodium alginate beads preparation, a uniform aqueous solution of sodium alginate is dropped carefully into a bath of calcium chloride. The immediate cross-linking reaction between the sodium ions on the alginate chain and the calcium divalent ions leads to quick gelation, generating sturdy hydrogel beads or juice balls used heavily in culinary arts, cell immobilization, and synthetic seed research.
What is the market price of Sodium Alginate powder per kg in India?
The wholesale sodium alginate price in India generally varies between ₹180 to ₹350 per kg depending on the technical parameters, viscosity grade, and whether it is textile grade, food grade, or pharmaceutical grade. For complete bulk commercial sheets and 25kg commercial packing rates, please reach out to DPRJ Universal.
