Product Overview and Characteristics

Propionic acid is a short-chain saturated organic acid with excellent antibacterial and anti-mold capabilities, demonstrating significant inhibitory effects against molds and yeasts. Under acidic conditions, its antimicrobial activity is enhanced, allowing it to inhibit microbial growth, delay material spoilage, and extend product shelf life. Propionic acid can be used as a preservative and acidity regulator, applicable both for feed mold prevention and in fields such as food and fine chemicals. It is a commonly used organic acid raw material in industrial applications.

High-efficiency mold prevention

As an acidic preservative, it effectively inhibits the growth of molds, yeasts, and aerobic bacteria, significantly extending the shelf life of feed, grain, and food.

Acidity regulation

As an organic acid, it can adjust the pH of a system, improve product taste and stability, and has broad applications in food processing and feed production.

Low toxicity and safe

Within reasonable usage limits, it is of low toxicity to humans and animals, can be normally metabolized, and meets food safety and feed safety standards.

Wide range of applications

Suitable for feed mold prevention, grain preservation, food preservation, and silage additives, it is an internationally recognized economical and efficient preservative variety.
