Calcium propionate

"Calcium propionate is an acid-type food preservative. Under acidic conditions, it generates free propionic acid, which has an antibacterial effect. Its antibacterial effect is influenced by the environmental pH value. The inhibition effect on molds is the best at a pH value of 5.0; the antibacterial ability significantly decreases at a pH value of 6.0, with the minimum inhibitory concentration being 0.01%. In acidic media (such as starch, protein-containing substances and oil substances), it has a strong inhibitory effect on various molds, Gram-negative bacilli or aerobic spore-forming bacteria. It can also inhibit the production of aflatoxin and is harmless to yeast, safe for both humans and animals, and has no toxic side effects. It is a new, safe and efficient food and feed preservative for preventing mold growth. As a preservative for feed, it is mainly used in protein feed, fish bait feed, and complete feed for aquatic animals. It is an ideal preservative for preventing mold growth in various feed processing enterprises, research institutions and other animal feed."
