Key Features and Benefits

Sodium Propionate serves primarily as a food preservative, especially in bakery and confectionery items where it inhibits the growth of molds and some bacteria. Featuring high purity (98% min.), low moisture content, and excellent solubility in water, it is suitable for pharmaceutical and personal care applications as well. Its long shelf life, mild characteristic odor, and white crystalline form underscore its reliability for industrial and food-grade use.

Safe Handling and Storage Guidelines

Sodium Propionate should be stored in a cool, dry place, away from moisture and direct sunlight to maintain its quality and efficacy throughout its 24-month shelf life. Packaging is typically in 25 kg bags or drums to facilitate convenient transport and safe storage. Always ensure the product is kept in tightly sealed containers to prevent contamination or degradation.

Applications Across Industries

Widely used as a food preservative (E281), Sodium Propionate helps maintain freshness and extend the shelf life of baked goods, cheeses, and processed foods. Its efficacy against mold makes it valuable in pharmaceuticals and personal care products. Manufacturers and suppliers in India distribute this versatile compound to bakeries, pharmaceutical companies, and personal care brands nationwide.

FAQs of Sodium Propionate:

Q: How is Sodium Propionate produced?

A: Sodium Propionate is synthesized through the neutralization of propionic acid using sodium carbonate or sodium hydroxide. This process results in a high-purity, white crystalline powder widely used as a preservative.

Q: What are the main uses of Sodium Propionate?

A: The primary application of Sodium Propionate is as a food preservative (E281), especially in bakery goods where it effectively inhibits mold and bacterial growth. It is also used in the pharmaceutical and personal care industries.

Q: When should Sodium Propionate be used in food products?

A: Sodium Propionate is typically added during the production or packaging stages of bakery products, cheeses, and processed foods to extend their freshness and shelf life by retarding spoilage caused by molds.

Q: Where should Sodium Propionate be stored to maintain its quality?

A: For optimal stability, Sodium Propionate should be kept in a cool, dry area away from moisture and direct sunlight, preferably in sealed containers such as the standard 25 kg bags or drums.

Q: What are the benefits of using Sodium Propionate over other preservatives?

A: Sodium Propionate offers superior mold inhibition without significantly impacting taste or texture. Its efficacy at slightly alkaline pH and minimal health risks make it a preferred choice for food and pharmaceutical applications.

Q: Can Sodium Propionate be easily dissolved for formulation purposes?

A: Yes, Sodium Propionate is highly water-soluble, being completely soluble in water and slightly soluble in alcohol, which simplifies its incorporation into various products.

Q: Is Sodium Propionate safe for long-term storage?

A: When stored properly in sealed containers away from heat and moisture, Sodium Propionate maintains its stability and effectiveness with a shelf life of up to 24 months.
