Calcium propionate is an acidic preservative, which forms propionic acid in acidic medium to exert antibacterial effect, and its antiseptic performance is the same as that of sodium propionate. Calcium propionate is relatively safe, and it is an antifungal agent for food and feed approved by the World Health Organization and the Food and Agriculture Organization of the United Nations. As a new type of additive, calcium propionate can prolong the fresh-keeping period of food and feed, and inhibit the growth of mold. With the advantages of safety, non-toxicity, and excellent anticorrosion, calcium propionate can replace some toxic sodium benzoate and potassium sorbate. The future application space broad.
What are the basic properties of calcium propionate?
Calcium propionate is also known as calcium initial oleate, and its appearance is white light scale crystal or white granule or powder. Calcium propionate is easily soluble in water, slightly soluble in ethanol, almost insoluble in acetone and benzene, and easily deliquescent in humid air. Calcium propionate has a wide range of antibacterial effects on bacteria, molds, yeasts, etc., and can be used as additives, preservatives, antifungal agents, dispersants, etc., and is used in food, feed, medicine, daily chemical products and other fields.
Where can calcium propionate be applied?
Calcium propionate can be used as a preservative in solid foods such as bread, pastry, cheese, etc., as an antifungal agent and mineral additive in the feed industry. Calcium propionate liquid wet acid preservative, its antibacterial effect is affected by the pH of the environment. The minimum inhibitory concentration is 0.01% at pH 5.0 and 0.5% at pH 6.5. It has a strong inhibitory effect on various molds, aerobic bacillus or gram-negative bacillus in acidic medium.
