Potassium Sulfates (E515)
Type of additive (Glossary) | Sequestrants |
E Number | E515 |
Chemical Formula | K2SO4 |
Also Known As | Potassium sulphate Sulphate of potash (SOP) Arcanite Potash of sulfur |

Purpose and Function
Potassium sulfates are primarily used as sequestrants in food applications:
- Sequestrant: They help bind free calcium and other minerals in food products, enhancing texture and stability.
- Flavor Enhancer: Potassium sulfates can contribute to the overall flavor profile of food products by providing a mild saltiness.
- Improves Shelf Life: By stabilizing food products, it help enhance shelf life and prevent spoilage.
Potential Risks and Side Effects
Potassium sulfates 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 sulfates.
- Allergic Reactions: Rarely, individuals may experience allergic reactions to potassium sulfates, particularly those sensitive to sulfate compounds.
- Contaminants: Sourcing from reputable suppliers is essential to minimize the risk of contaminants in food formulations.
