Potassium Propionate Description


Potassium propionate ,other name Propanoic acid,potassium salt,Potassium propanoate.The appearance is white granules.EEC approved for use in processed cheese, baked goods, puddings,dairy products.

Potassium Propionate Antimicrobial


Under acidic conditions, it produces free propionic acid, which has antibacterial effect but has no effect on yeast.Application: preservative and mildew – proof agent.Can be used for bread, cakes, dairy products, cheese, pudding anticorrosive.It inhibits the growth of Bacillus aerophilus, which causes the filamentous sticky substance in bread.Used in beer production can inhibit the formation of adverse viscous substances.

Potassium Propionate Used In Feed

Any compound feed is easy to be spoiled by mildew.Certain molds produce a chemical called MYC6 toxin.This substance is toxic and can adversely affect animal health and performance, and ultimately endanger human health.
Potassium propionate preservative has both the good processing property of neutral salt and the high anti-mold activity of propionate.Moreover, unlike propionic acid absorbed into the carrier, potassium propionate does not have the undesirable pungent odor and greatly reduces the evaporation loss of acid.
Especially in the case of animal feed used as feed additives and poultry, low levels of potassium ions are beneficial because potassium in this case may show a diuretic effect.
