Description:

Ammonium Carbonate (food grade) is a white, crystalline, highly soluble inorganic salt composed of ammonium and carbonate ions. It has a strong characteristic ammonia-like odor and decomposes slowly in air to form ammonia, carbon dioxide, and water. Commercially, it is often supplied as a mixture of ammonium bicarbonate and ammonium carbamate.

Chemical Name: Ammonium Carbonate
Chemical Formula: (NH₄)₂CO₃
Molecular Weight: 96.09 g/mol
CAS Number: 506-87-6

Appearance:

White, crystalline solid or powder with a strong ammonia-like odor.

Purity (Food Grade):

Typically ≥ 99% (on dry basis), with controlled impurity levels to meet Food Chemicals Codex (FCC) and E503 (EU Food Additive) standards.

Functional Uses:

• Leavening Agent: Used in baking applications such as cookies, crackers, and traditional baked goods (e.g., “hartshorn”).

• Buffering Agent: Helps regulate pH in food processing.

• Foaming Agent: Used in certain confectioneries.

• Stabilizer and Acidity Regulator: Enhances product consistency and shelf stability.

Solubility:

Soluble in water; insoluble in alcohol.

Decomposition:

Decomposes upon heating or prolonged exposure to air, releasing ammonia (NH₃) and carbon dioxide (CO₂) gases.

Storage:

Store in a cool, dry, well-ventilated area in tightly closed containers. Protect from moisture, heat, and prolonged exposure to air to minimize decomposition.

Safety and Handling:

• Non-toxic at approved food-grade levels.

• May cause irritation to eyes, skin, and respiratory tract in concentrated form.

• Use appropriate ventilation and personal protective equipment (PPE) when handling large quantities.

Food Additive Code:

E503 (Ammonium Carbonates)
