E261: Potassium acetate

Potassium acetate crystals E261 is the European food additive code for potassium acetate, a chemical compound commonly used in the food industry as a preservative and acidity regulator. It is the potassium salt of acetic acid and is known for its versatile properties and wide range of applications.

Chemical Properties

Potassium acetate has the chemical formula CH3COOK and a molar mass of approximately 98.14 g/mol. It is a white crystalline powder that is highly soluble in water. The compound is non-toxic and has a faint vinegar-like odor.

Uses

Potassium acetate is primarily used as a food additive due to its ability to prevent the growth of bacteria and fungi, thus extending the shelf life of various food products. It is commonly found in processed meats, bakery products, and dairy items. Additionally, it is used as an acidity regulator in certain beverages and as a flavor enhancer in some food preparations.

Benefits

The use of potassium acetate offers several benefits in the food industry. Firstly, it acts as a preservative, inhibiting the growth of microorganisms and preventing spoilage. This helps to maintain the quality and freshness of food products for a longer period. Secondly, it serves as an acidity regulator, helping to control the pH levels of food and beverages. Lastly, potassium acetate can enhance the flavor of certain foods, providing a tangy and slightly sour taste.

Safety and Regulations

Potassium acetate is generally recognized as safe (GRAS) by regulatory authorities, including the European Food Safety Authority (EFSA) and the U.S. Food and Drug Administration (FDA). It has been extensively studied and found to have no adverse effects on human health when consumed in normal amounts. However, individuals with specific health conditions, such as kidney problems, should consult with a healthcare professional before consuming foods containing potassium acetate.
