Calcium propionate is a safe and reliable antifungal agent for food and feed approved by the World Health Organization (WHO) and the United Nations Food and Agriculture Organization (FAO). Like other fats, calcium propionate can be absorbed by humans and animals through metabolism, and supplies necessary calcium for humans and animals. This advantage is unmatched by other antifungal agents and is considered GRAS. The calcium propionate produced by our company uses high-purity imported pro-pionic acid and ion-exchange membrane liquid caustic as raw materials, and has stable quality. Due to high temperature resistance, the anti-corrosion effect is better than other products. Calcium propionate is an acid-type food preservative. Under acidic conditions, it produces free pro-pionic acid and has antibacterial effects. Its antibacterial effect is affected by the pH value of the environment. The inhibitory effect of mold is best at pH 5.0; the antibacterial ability is significantly reduced at pH 6.0, and the minimum inhibitory concentration is 0.01%
