Product Description

Potassium propanoate or potassium propionate has formula K(C2H5COO). Its melting point is 410 °C. It is the potassium salt of propanoic acid.


[1]  As a food additive, it is listed as E number 283 in the Codex Alimentarius. sodium propionate is used as a preservative in a wide variety of products, including but not limited to bread, other baked goods, processed meat, whey, and other dairy products.
[2]  In agriculture, it is used, amongst other things, to prevent milk fever in cows and as a feed supplement
[3]  Propionates prevent microbes from producing the energy they need, like benzoates do. However, unlike benzoates, propionates do not require an acidic environment.
[4]  Potassium propionate is used in bakery products as a mold inhibitor, typically at 0.1-0.4%
[5]  Potassium propionate can be used as a pesticide
