Propionic acid uses in the feed industry
Propionic acid plays an important role in the feed industry as an effective feed preservative and mold inhibitor. Gneebio's propionic acid is widely used as a feed antifungal agent, pharmaceutical and pesticide intermediate, and grain preservative. Both propionic acid and its salts help maintain the natural flavor and nutritional value of grains during long-term storage.

Propionic acid antifungal agent
As a volatile organic acid, propionic acid releases vapors that evenly contact the feed surface, providing broad-spectrum and efficient antimicrobial protection. It effectively inhibits molds and bacteria such as Aspergillus flavus, Salmonella, yeasts, and spore-forming bacteria. Many commercial mold inhibitors (e.g., Propionibac, Moldban) use propionic acid as their main component.
Combination of Propionic Acid and Propionate Salts
Combining propionic acid with sodium propionate improves stability and long-term protection. Sodium propionate offers slow release, high temperature resistance, and reduced volatility, making it ideal for feed pelleting and storage in humid climates.
propionic acid silage additive
In silage feed, propionic acid and its salts (e.g., calcium propionate, sodium propionate, ammonium propionate) help control harmful microorganisms during fermentation, preventing spoilage. Studies show propionic acid reduces mold and Clostridium levels while improving silage quality and fermentation stability.
Advantages of Propionate Salts
While liquid propionic acid may evaporate during pelleting, propionate salts are non-volatile, heat-resistant, and less corrosive, suitable for long-term storage. They convert back into active propionic acid under appropriate moisture and pH conditions, ensuring continuous antifungal performance.
