Potassium sorbate is a preservative found in many foods. Among other things, it is often found in margarine, baked goods and meat substitute products. Here you can find out what dangers are known about potassium sorbate.

Potassium sorbate (E202) is found in many sauces, baked goods, jams and meat substitutes. As a preservative, it is said to extend the shelf life of food. It prevents mold from forming and spoiling the food.

Potassium sorbate is also used in cosmetics and in wine production. However, the substance is controversial: critics fear that potassium sorbate could be unhealthy for humans and that it poses a risk.

Potassium sorbate (E202): That’s behind the substance

Potassium sorbate is a tasteless and odorless preservative that also occurs in nature. It is found in rowan berries, for example. However, as a food additive, the substance is produced chemically. The European Food Safety Authority (Efsa) recommends that a daily dose of three milligrams per kilogram of body weight should not be exceeded.

In principle, potassium sorbate is considered harmless. The human body breaks down the substance completely. However, there are indications that potassium sorbate can lead to skin reactions in allergy sufferers. However, this has only been proven for direct allergy tests on the skin. The amount of potassium sorbate in food is so small that no reaction occurs.

Is Potassium Sorbate Carcinogenic?

A 2010 study indicates that potassium sorbate may be harmful to white blood cells. They protect our immune system by recognizing and fighting bacteria and viruses. In addition, potassium sorbate is said to increase the risk of chromosomal aberrations, such as trisomy. This deviation of the chromosomes can in turn trigger the development of cancer, the scientists write in the study.

However, the extent of the damage caused by potassium sorbate for humans cannot be derived from the study. Because these were experiments in the test tube, which do not allow any conclusions to be drawn about humans.
