About This Product
Ammonium propionate is the ammonium salt of propionic acid, formula C3H9NO2, with CAS number 17496-08-1. It is supplied as a clear aqueous solution, typically around 50 percent, or absorbed onto a solid carrier for dry dosing. Unlike the calcium and sodium propionates it is hygroscopic and deliquescent, which is why it is normally handled in liquid form.
Its preservative action is the same as that of all propionates: the undissociated propionic acid crosses the cell membrane of moulds and yeasts, dissociates inside at the higher internal pH and disrupts the cell's energy metabolism. Activity therefore depends on the pH of the substrate, and it works best in acidic conditions. What distinguishes the ammonium salt from the others is the cation. Where calcium propionate adds calcium and sodium propionate adds sodium, the ammonium form contributes neither, and in ruminant feed the ammonium ion is itself useful as a source of non-protein nitrogen that rumen microbes can convert to protein. It is also less corrosive to equipment than free propionic acid.
It is used to preserve high-moisture grain, hay and total mixed rations, in compound feed manufacture, and as a mould inhibitor in bakery applications where the ammonium form is permitted.
Bio Green Foods supplies ammonium propionate to specification on assay, propionic acid content, pH, colour and heavy metals, with permitted-use status confirmed for the destination market.
