E283 - Kaliumpropionat

Origin

Potassium propionate is the potassium salt of propionic acid. Propionic acid occurs naturally in some foods and is also produced during the fermentation of certain foods. Potassium propionate is synthetically produced for use as a food preservative.

Usage

Potassium propionate is primarily used as a preservative in baked goods to inhibit the growth of mold and other microorganisms, thereby extending shelf life. It is effective at preventing the growth of a wide range of molds and some bacteria. It is often used in bread, cakes, pastries, and other baked products. The typical usage levels vary depending on the application, but are generally within the range of 0.1% to 0.3% by weight of the finished product. It can also be found in some cheeses and processed meats.

Side Effects

Potassium propionate is generally considered safe for consumption at the levels typically used in food. Propionates are metabolized in the body similarly to other short-chain fatty acids. Some individuals may experience mild gastrointestinal discomfort, such as bloating or nausea, especially with high intakes. However, such reactions are rare. No Acceptable Daily Intake (ADI) has been specified by regulatory bodies, indicating its low toxicity. Studies have shown that propionates are rapidly metabolized and do not accumulate in the body.

Regulatory Status

Potassium propionate (E283) is approved for use as a food additive in many countries, including the European Union and the United States. In the EU, its use is regulated under Regulation (EC) No 1333/2008 on food additives. In the United States, it is Generally Recognized As Safe (GRAS) by the Food and Drug Administration (FDA) under 21 CFR 184.1631.
