Potassium Ferrocyanide (E536)
| Type of additive (Glossary) | Acidity Regulators Anti-caking Agents |
| E Number | E536 |
| Chemical Formula | K4[Fe(CN)6] |
| Also Known As | Potassium hexacyanidoferrate(II) |
Purpose and Function
Potassium ferrocyanide is primarily used as an acidity regulator in food applications:
- Acidity Regulator: It helps maintain pH levels in food products, contributing to flavor and preservation.
- Anticaking Agent: Commonly used in salt and powdered foods to prevent clumping.
- Food Processing Aid: It can be involved in various food processing applications, enhancing texture and stability.
- Improves Shelf Life: By stabilizing food products, potassium ferrocyanide helps enhance shelf life and prevent spoilage.
Potential Risks and Side Effects
Potassium ferrocyanide is generally regarded as safe for consumption in regulated amounts. However, some concerns include:
- Toxicity in Excess: While considered safe in small amounts, excessive consumption could potentially lead to toxicity.
- Allergic Reactions: Rarely, individuals may experience allergic reactions to potassium ferrocyanide, particularly those with sensitivities to cyanide compounds.
- Contaminants: Sourcing from reputable suppliers is essential to minimize the risk of contaminants in food formulations.
