Overview：
Calcium propionate is an acid-type food preservative. Under acidic conditions, it produces free propionic acid, which has antibacterial effect. Its antibacterial effect is affected by the pH value of the environment, and the inhibitory effect on mold is the best when the pH value is 5.0. The antibacterial ability was significantly reduced when the pH value was 6.0, and the minimum inhibitory concentration was 0.01%. It has strong inhibitory effect on various molds, Gram-negative bacilli or aerobic bacilli in acidic media (starch, protein and oily substances). It can also inhibit the production of aflatoxin, and is harmless to yeast, humans and animals, and has no toxic or side effects. It is a new, safe and efficient antifungal agent for food and feed in food, brewing, feed, and traditional Chinese medicine preparations.
Characters：
Calcium propionate is white crystal or white crystal powder or granule, odorless or slightly smell of propionic acid. Calcium propionate used as a food additive is a monohydrate salt, stable to water and heat, hygroscopic, easily soluble in water, 39.9g/l00mL (20°C), insoluble in ethanol and ether. Add the same amount of dilute sulfuric acid to 10% calcium propionate aqueous solution, and heat it to release the special smell of propionic acid. Calcium propionate is alkaline, and the pH value of its 10% aqueous solution is 8~10.
The antiseptic performance of calcium propionate is the same as that of sodium propionate, and it forms propionic acid in acidic medium to play a bacteriostatic effect. The effective dose of calcium propionate to inhibit mold is smaller than that of sodium propionate, but it can reduce the effect of chemical leavening agents, so sodium propionate is commonly used. However, its advantage is that the use of calcium propionate in pastry, bread and cheese can supplement the calcium in food. Calcium propionate can inhibit the reproduction of Bacillus subtilis during dough fermentation. The minimum antibacterial mass fraction is 0.01% when the pH value is 5.0, and 0.188% when the pH value is 5.8. The optimum pH value should be lower than 5.5.
Application:
Calcium propionate is a new type of food additive. It is a safe and reliable antifungal agent for food and feed approved by the World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO). Calcium propionate has a wide range of antibacterial effects on mold, yeast and bacteria.
1. Calcium propionate is used as a preservative for bread and pastries. Calcium propionate is easy to mix evenly with flour, and it can provide calcium necessary for human body while serving as a fresh-keeping preservative, and play a role in strengthening food.
2. Calcium propionate has an inhibitory effect on mold and aerobic bacillus that can cause sticky material in bread, but has no inhibitory effect on yeast.
3. It is effective against mold, aerobic spore-producing bacteria, Gram-negative bacteria, aflatoxin, etc. in starch, protein and oily substances, and has unique anti-mildew and anti-corrosion properties.
4. It is a new type, safe, efficient, broad-spectrum antifungal agent for food and feed in the aspects of food, brewing, feed, and traditional Chinese medicine preparations.
5. As a feed additive, calcium propionate can effectively inhibit the mold of feed and prolong the shelf life of feed. If it is combined with other inorganic salts, it can also increase the appetite of livestock and increase the milk production of dairy cows. Calcium propionate has low volatility, high temperature resistance, good animal adaptability, and is suitable for various feeds.
6. Calcium propionate can also be used as an additive in toothpaste and cosmetics, and has a good antiseptic effect.
7. A new type of feed additive, mainly used as an antifungal agent, which can prolong the fresh-keeping period of feed. It has good anti-kill effect on mold, aerobic bud-producing bacteria and Gram-negative bacteria, and can also inhibit the production of aflatoxin. It is harmless to yeast, human and livestock, and has no toxic and side effects. It can also be used as a food preservative.
POLIFAR, which has been established for more than ten years, focuses on the production of calcium propionate. Here you will find the required calcium propionate.
