Food Grade Sodium Nitrite – Preservative and Color Fixative for Processed Meats

Food Grade Sodium Nitrite (NaNO₂) is a white to slightly yellowish crystalline powder widely used in the food industry, particularly in processed meat products. It serves as a curing agent, preservative, and color fixative. Its primary functions include inhibiting the growth of harmful bacteria such as Clostridium botulinum, stabilizing the pink-red color of cured meats, and contributing to flavor development.

Chemical Information

• CAS No.: 7632-00-0

• E Number: E250

• Molecular Formula: NaNO₂

• Appearance: White or slightly yellowish powder

• Solubility: Highly soluble in water

Main Applications

1. Meat Curing:
Sodium nitrite is an essential curing agent for processed meat products such as:

• Ham

• Bacon

• Sausages

• Hot dogs

• Corned beef
  It helps develop the characteristic pink color, cured flavor, and prevents microbial spoilage.

2. Antimicrobial Agent:
Effectively inhibits the growth of Clostridium botulinum, the bacteria responsible for botulism, making it crucial for food safety in vacuum-packed and canned meats.

3. Shelf Life Extension:
Reduces the risk of spoilage and rancidity, prolonging the shelf life of cured and processed meats under refrigerated conditions.
