| Type of additive (Glossary) | Acidity Regulators Leavening Agents |
| E Number | E500 |
| Subtypes | Sodium Carbonate (E500i) Sodium Bicarbonate (E500ii) Sodium Sesquicarbonate (E500iii) |
Purpose and Function
Sodium carbonates are commonly used in food applications for their acidity-regulating properties:
- Acidity Regulator: They help maintain pH levels in food products, contributing to flavor and preservation.
- Leavening Agent: Sodium bicarbonate is widely used as a leavening agent in baked goods, producing carbon dioxide when reacting with acids.
- Buffering Agent: Sodium sesquicarbonate acts as a buffering agent, stabilizing pH in various food formulations.
- Improves Texture: Sodium carbonates can improve the texture of certain food products by enhancing moisture retention.
Potential Risks and Side Effects
Sodium carbonates are generally regarded as safe for consumption. However, some considerations include:
- Gastrointestinal Issues: Excessive intake may lead to gastrointestinal discomfort, including bloating or gas, particularly for those sensitive to high sodium levels.
- Allergic Reactions: Rarely, individuals may experience allergic reactions to sodium carbonates, particularly those with sensitivities to sodium or carbonate compounds.
- Contaminants: Sourcing from reputable suppliers is essential to minimize the risk of contaminants in food formulations.
