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.
✔ 풍미 강화제 – Provides a mild vinegar-like taste in seasonings.
✔ 부식 억제 – 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

생산 과정:

1️⃣ Reaction Formation: Sodium carbonate (Na₂CO₃) reacts with acetic acid (CH₃COOH) to form sodium diacetate.
2️⃣ 결정화: The solution is evaporated to obtain solid sodium diacetate.
3️⃣ 건조 및 포장: 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%)
