E202 Preservative

Potassium sorbate (E202) is the potassium salt of sorbic acid. It is a naturally occurring compound found in the berries of the mountain ash tree (Sorbus aucuparia), but is typically manufactured synthetically for use as a food additive. It is produced by neutralising sorbic acid with potassium hydroxide.

Potassium sorbate is a widely used preservative, effective at inhibiting the growth of mould, yeast, and some bacteria. This helps to extend the shelf life of food products. It is commonly found in baked goods, dairy products, dried fruits, and beverages.

Potassium sorbate is authorised as a food additive in Great Britain and is listed on the Register of Food Additive Authorisations. European Food Safety Authority (EFSA) has evaluated potassium sorbate and established an acceptable daily intake (ADI). Evidence does not suggest adverse health effects at typical consumption levels. Some individuals may experience mild allergic reactions or sensitivities, though this is rare.
