Propionic acid application
In the feed industry, propionic acid also has important applications. It can be used as a preservative for silage. Silage is susceptible to microbial damage during storage, and propionic acid can inhibit the growth of harmful microorganisms, preventing the silage from heating, molding, or spoiling, thereby preserving its nutritional content and palatability. For example, in dairy farming, adding propionic acid to silage corn helps preserve it better, providing high-quality feed for cows, which can improve milk yield and quality.
