Ammonium propionate

Ammonium propionate (CAS 17496-08-1) is the ammonium salt of propionic acid, commercially recognized as ammonium propanoate. It functions as a mold inhibitor and preservative in food and agricultural feed applications. In these industries, controlled microbial activity is the primary requirement for product stability. In baked goods and processed foods, it extends shelf life by inhibiting mold and rope-forming bacteria.

This additive works without significantly affecting yeast activity, making it suitable for bread and bakery formulations. Animal feed manufacturers apply it as an antifungal treatment in grain storage and compound feeds. This application protects nutritional integrity during storage and transit. It also functions as a flavoring agent and acidulant in food systems where a mild, slightly acidic profile is required for the final product.

In silage treatment, it supports fermentation control and reduces spoilage losses in forage preservation. The chemical is supplied as a white crystalline powder or in aqueous solution form, depending on requirements. Food-grade specifications, often meeting FCC standards, are the most commonly traded. Technical-grade material is also available for specific agricultural and feed use where high purity is less critical.

Buyers typically source it in bulk bags or drums, with solution concentrations varying by supplier. It remains a vital component for ensuring the safety and longevity of various perishable agricultural commodities.
