Calcium propionate is white crystalline particles or crystalline powder. Odorless or slightly propionic acid odor, hygroscopicity, soluble in water, insoluble in alcohol. Calcium propionate is a safe and reliable anti-mildew agent for food and feed approved by World Health Organization (WHO) and FAO. Like other fats, calcium propionate can be absorbed by humans and animals through metabolism, and provide essential calcium for humans and animals. This advantage is uncomparable with other anti-mildew agents, and is considered GRAS. The CALCIUM PROPIONATE PRODUCED BY OUR COMPANY ADOPTS HIGH PURITY IMPORTED PROPIonate and IONIC membrane liquid alkali as raw materials, with stable quality AND BETTER ANTI-corrosion effect than other products due to high temperature resistance.

Calcium Propionate

Calcium propionate is an acid-type food preservative that, under acidic conditions, produces free propionate, which has Antibacterial effects. Its bacteriostatic effect is affected by the pH value of the environment, and the best inhibitory effect is achieved when the pH value is 5.0. At pH 6.0, the antibacterial ability decreased significantly, and the minimum inhibitory concentration was 0.01%. Calcium propionate is a relatively new food antimildew agent, calcium salt of acid antimildew agent propionate, the appearance is white crystal or powder, odorless or slightly specific propionate odor, stable to light and heat, hygroscopic, easily soluble in water, aqueous solution is weakly alkaline, slightly soluble in methanol, ethanol, insoluble in benzene and acetone. It is easy to deliquesize in moist air, loses crystal water when heated to 120℃, and changes phase at 200 ~ 210℃, decomposes into calcium carbonate at 330 ~ 340℃. Under acidic conditions,

free propionic acid is produced, which is weaker than sorbic acid and stronger than acetic acid. It has antibacterial effect, and has inhibitory effect on Aspergillus Niger and gasophilic Bacillus, but has no effect on yeast. Calcium propionate is a normal intermediate product of animal metabolism. It is safe to be eaten by animals. It HAS a wide range of antibacterial effects on mold, zyme and bacteria, inhibit microbial reproduction, can prevent mold of feed, can be used as mildew proof agent of food and feed and preservation agent of bread and pastry. As a feed additive, it can effectively inhibit feed mildew and prolong feed storage period. If combined with other inorganic salts, it can also improve the appetite of livestock and milk production of dairy cows. The added amount of the additive is less than 0.3% of the compound feed (calculated by propionate). Chinese regulations as Food Additives, according to GB2760-86 implementation, its use scope is only bread, vinegar, soy sauce, soy products, the maximum use of 2.5g/kg.
