Property:

White crystal, soluble in water, weakly acidic in aqueous solution, pH of 10% aqueous solution is 4-6, insoluble in methanol and ethanol; It can absorb moisture from the air;

Usage:

Main use as anti-corrosion, anti-mildew agent. Free propionic acid is produced under acidic conditions and has antibacterial properties. It has special effect on preventing the production of aflatoxin, but has almost no effect on yeast. It has good effect on various molds and gram-negative bacilli. The lower the pH value, the better the anti-corrosion effect. It has good effect on preventing mildew and caking of grain. Feed and grain preservatives mainly use a combination of propionic acid and ammonium propionate.
