E515ii - Kaliumhydrogensulfat

Origin

Potassium hydrogen sulphate, also known as potassium bisulphate, is an inorganic salt formed by the partial neutralization of sulfuric acid with a potassium-containing base, such as potassium hydroxide or potassium chloride. It exists as a white, crystalline solid and is highly soluble in water. It is primarily manufactured through a chemical process involving the reaction of sulfuric acid with a potassium compound.

Usage

In the food industry, potassium hydrogen sulphate is used as an acidity regulator. It helps to maintain a specific pH level in food products, which is crucial for controlling microbial growth, enzymatic activity, and overall product stability. It can be found in various processed foods, including sauces, condiments, and certain baked goods. It is also used in winemaking to adjust the acidity of the must. Beyond food, it has applications in chemical analysis, as a flux in metallurgy, and in the production of other potassium compounds.

Side Effects

Potassium hydrogen sulphate is generally considered safe for consumption when used in accordance with Good Manufacturing Practices (GMP) and within established regulatory limits. As an acidity regulator, it is used in small quantities. However, excessive consumption of acidic substances can potentially lead to gastrointestinal discomfort in sensitive individuals. There is no established Acceptable Daily Intake (ADI) specifically for potassium hydrogen sulphate, but its use is regulated to ensure that it does not pose a health risk. Individuals with potassium imbalances or kidney problems should exercise caution, as with any potassium-containing compound.

Regulatory Status

Potassium hydrogen sulphate (E515ii) is permitted for use as a food additive in the European Union (EU) under Regulation (EC) No 1333/2008 on food additives. Its use is subject to specific conditions and maximum levels in certain food categories. The safety of potassium hydrogen sulphate has been evaluated by scientific bodies such as the European Food Safety Authority (EFSA). Regulations may vary in other countries, but it is generally approved for use as an acidity regulator where needed.
