Application / Intended Use
Propionic acid and its salts are the standard mould inhibitor in bakery and animal feed. Bakers use it at roughly 0.1-0.3% of flour weight to extend shelf life in bread and tortillas without affecting yeast; feed mills apply it to grain at harvest moisture to prevent mould during storage. It is also an intermediate for herbicides and cellulose acetate propionate.
