kaliumpropionaatti

Kaliumpropionaatti, also known as potassium propionate, is the potassium salt of propionic acid. Its chemical formula is C3H5KO2. It appears as a white crystalline solid and is soluble in water.

This compound is primarily used as a food preservative. It functions by inhibiting the growth of molds and some bacteria, thereby extending the shelf life of various food products. It is particularly effective in baked goods, where it helps prevent spoilage and maintains freshness. Kaliumpropionaatti is often found in breads, cakes, and other bakery items.

In the food industry, it is identified by the E number E283. Its use as a food additive is regulated in many countries, with specific limits on the maximum concentration allowed in different food categories. Regulatory bodies assess its safety based on scientific studies.

Beyond its use in food, kaliumpropionaatti may also find applications in other areas, though these are less common. For example, it can be used as a desiccant in some industrial processes. The manufacturing process typically involves the neutralization of propionic acid with a potassium source, such as potassium hydroxide.
