Sodium Diacetate (E262(ii))

Sodium diacetate (NaH(C₂H₃O₂)₂) is a white, crystalline, free-flowing powder with a mild acetic acid odor. It consists of sodium acetate and acetic acid in a 1:1 molar ratio. This compound is widely used as a pH regulator, preservative, and flavoring agent in food, agriculture, and industrial applications.

• Chemical Formula: NaH(C₂H₃O₂)₂

• Molecular Weight: 142.09 g/mol

• CAS Number: 126-96-5

• E Number: E262(ii)

Key Functional Properties

✔ Buffered pH Control – Maintains stable pH in food and industrial applications.
✔ Antimicrobial Activity – Inhibits bacterial and mold growth.
✔ Preservative Effect – Extends food shelf life.
✔ Flavor Enhancer – Provides a mild vinegar-like taste in seasonings.
✔ Corrosion Inhibition – Used in industrial applications for metal protection.

Sodium diacetate is produced by reacting sodium carbonate or sodium hydroxide with acetic acid under controlled conditions.

Reaction Equation:

Na₂CO₃ + 4CH₃COOH → 2NaH(C₂H₃O₂)₂ + CO₂ + H₂O

Production Process:

1️⃣ Reaction Formation: Sodium carbonate (Na₂CO₃) reacts with acetic acid (CH₃COOH) to form sodium diacetate.
2️⃣ Crystallization: The solution is evaporated to obtain solid sodium diacetate.
3️⃣ Drying & Packaging: The final product is dried and packed in moisture-resistant bags.

Raw Materials Required:

• Sodium Carbonate (Na₂CO₃) or Sodium Hydroxide (NaOH)

• Glacial Acetic Acid (CH₃COOH, >99%)

? Food Industry (E262(ii))

• Used in baked goods (bread, tortillas, cakes) to prevent mold growth.

• Common in meat preservation (cured meats, sausages, processed poultry).

• Enhances the flavor and stability of snacks, sauces, and spice blends.

• Controls pH levels in dairy products and beverages.

? Agriculture & Animal Feed

• Mold inhibitor in animal feed, preventing spoilage.

• Preserves silage and grain storage, reducing microbial damage.

? Industrial Applications

• Corrosion inhibitor in metal treatment and coatings.

• De-icing agent in aviation and road maintenance.

• pH stabilizer in detergents and chemical formulations.

? Pharmaceutical Industry

• Used in oral medications for pH control.

• Helps in buffered tablet formulations.

? As a Preservative:

• Lowers food pH, inhibiting microbial growth.

• Acetic acid disrupts bacterial cell membranes, preventing proliferation.

? As a pH Buffer:

• Maintains optimal pH (4.5-5.0) to prevent food spoilage due to excessive alkalinity or acidity.

? As a Corrosion Inhibitor:

• Forms a protective layer on metal surfaces, reducing oxidation and corrosion.
