Brief introduction of calcium propionate:
Calcium propionate is an acid-type food preservative. Under acidic conditions, it produces free propionic acid and has an antibacterial effect. Its antibacterial effect is affected by the pH value of the environment. The inhibitory effect of mold is best when the pH value is 5.0; the antibacterial ability is significantly reduced when the pH value is 6.0, and the minimum inhibitory concentration is 0.01%. It has a strong inhibitory effect on various molds, gram-negative bacilli or aerobic bacillus in acid medium (starch, protein and oil-containing substances), and can also inhibit the production of aflatoxin, but has no effect on yeast. Harmless, harmless to humans and animals, no toxic side effects. It is a new, safe and efficient antifungal agent for food and feed in food, brewing and feed.

Properties of calcium propionate: white powder or monoclinic crystals. The solubility in 100g of water is: 20°C, 39.85g; 50°C, 38.25g; 100°C, 48.44g. Slightly soluble in ethanol and methanol, almost insoluble in acetone and benzene.

Types of calcium propionate: There are three types of calcium propionate on the market: 1. Propionic acid is the propionic acid of Pashiv, mainly used as a food supplement. 2. Propionic acid is common propionic acid used as a side material. For example, it is directly mixed in corn and trace elements. 3. As a preservative, a kind of non-national standard.
