Calcium propionate is an acid-type food preservative. Under acidic conditions, it produces free propionic acid, which has antibacterial properties. Its antibacterial effect is influenced by the environmental pH value. The inhibitory effect on molds is the best at a pH value of 5.0; at a pH value of 6.0, the antibacterial ability significantly decreases, 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 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. In medicine, propionate salts can be made into powder, solution and ointment to treat diseases caused by parasitic molds on the skin.

Calcium propionate is a white crystalline substance or white powder or granules, odorless or slightly having the smell of propionic acid. The calcium propionate used as a food additive is a monohydrate salt, stable to water and heat, hygroscopic, soluble in water (39.9g/100mL at 20℃), insoluble in ethanol and ether. When the same amount of dilute sulfuric acid is added to a 10% calcium propionate aqueous solution and heated, it can release the special smell of propionic acid. Calcium propionate is alkaline, and the pH value of its 10% aqueous solution is 8-10.
The preservative property of calcium propionate is the same as that of sodium propionate. It forms propionic acid in an acidic medium to exert antibacterial effects. 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. Therefore, sodium propionate is commonly used. However, its advantage is that calcium propionate can be used in pastries, bread and cheese to supplement calcium in the diet. Calcium propionate can inhibit the reproduction of Bacillus subtilis during dough fermentation. The minimum inhibitory mass fraction is 0.01% at a pH of 5.0, 0.188% at a pH of 5.8, and the optimal pH should be lower than 5.5.

Products Application

Used as a preservative for bread, pastries and cheese, as well as a mold inhibitor for feed. As a food preservative, the acetate salts, calcium acetate are mainly used for bread because sodium acetate raises the pH value of the bread, delaying the fermentation of the dough; sodium acetate is more commonly used in pastries because the leavening of pastries uses synthetic leavening agents and there are no yeast development problems caused by pH value increase. As a feed preservative, the effect of sodium acetate is better than that of calcium acetate. However, calcium acetate is more stable than sodium acetate. Acetate salts are used in food not only for bread, pastries, cheese, etc., but also for mold prevention in soy sauce and to inhibit re-fermentation. In medicine, acetate salts can be made into powders, solutions and ointments to treat skin parasitic fungi-related diseases. The ointment (liquid) contains 12.3% sodium acetate, and the powder contains 15% calcium acetate.

Purpose
Calcium propionate is a new type of food additive, which is approved by the World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO) as a safe and reliable anti-mold agent for food and feed. Calcium propionate has a wide range of antibacterial effects on molds, yeasts, and bacteria.
1. Calcium propionate can be used as an anti-mold agent for food and feed, and is used as a preservative for bread and pastries. Calcium propionate is easy to be mixed evenly with flour and can provide essential calcium for the human body while serving as a preservative, achieving the effect of strengthening food.
2. Calcium propionate has inhibitory effects on molds and aerobic spore-forming bacteria that can cause sticky substances in bread. It has no inhibitory effect on yeast.
3. It is effective against molds, aerobic spore-forming bacteria, Gram-negative bacteria, and aflatoxins in starch, protein-containing substances, and oil substances, and has unique anti-mold and anti-corrosion properties.
4. It is a new and safe, efficient, and broad-spectrum anti-mold agent for food and feed, as well as for food production, feed, and traditional Chinese medicine preparations.
5. As a feed additive, calcium propionate can effectively inhibit mold growth in feed and extend the preservation period of feed. When 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 heat resistance, and good animal adaptability, and is suitable for use in various feeds.
6. Calcium propionate can also be used as an additive in toothpaste and cosmetics, achieving good anti-corrosion effects.
7. It is a new type of feed additive, mainly used as an anti-mold agent, which can extend the preservation period of feed. It has good inhibitory effects on molds, aerobic spore-forming bacteria, Gram-negative bacteria, and can inhibit the production of aflatoxins. It is harmless to yeast and is safe for humans and animals, with no toxic side effects. It can also be used as a food preservative.
