What is calcium propionate?

Calcium propionate is an important chemical substance that plays an irreplaceable role in many fields, especially in the food, feed and pharmaceutical industries. The following is a detailed description of calcium propionate, including its basic properties, production and preparation, application fields and safety.

1. Basic properties

Calcium propionate , with a molecular formula of C6H10CaO4 and a relative molecular mass of 186.22 (anhydrous state). It usually appears as white light flaky crystals, or white granules, powder, odorless or slightly propionic acid smell. Calcium propionate is easily deliquescent in humid air, easily soluble in water, slightly soluble in ethanol, and insoluble in ethers. In addition, calcium propionate is sensitive to light and heat, and decomposes into calcium carbonate at 330-340°C.

2. Production and preparation

The main raw material for calcium propionate is propionic acid, which is obtained by reacting with calcium hydroxide or calcium carbonate. This reaction process is relatively simple and efficient, allowing calcium propionate to be produced on a large scale to meet market demand.

3. Application fields

Food industry:

Preservative: Calcium propionate is a safe and reliable mildew preventer for food and feed approved by the World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO). Under acidic conditions, calcium propionate can decompose to produce free propionic acid, which has a wide range of antibacterial effects and can effectively inhibit the growth of molds, yeasts and bacteria. Therefore, calcium propionate is often used for the preservation and freshness of foods such as bread, cakes, and soy products to extend their shelf life.

Nutritional supplement: Calcium propionate can not only be used for preservation, but also provide calcium supplements for food, especially when used in foods such as bread and cheese, it can significantly increase the calcium content of food, which helps the body absorb and utilize calcium.

Feed industry:

Calcium propionate is also widely used in the feed industry as a mildew preventer and nutritional additive for feed. It can not only effectively prevent feed from mildewing, but also provide animals with necessary calcium and promote the healthy growth of animals.

Pharmaceutical industry:

Calcium propionate also has certain application value in the pharmaceutical field. As an organic calcium supplement, calcium propionate can be used to treat related diseases caused by calcium deficiency, such as osteoporosis. At the same time, calcium propionate also has health benefits such as enhancing immunity and improving muscle strength. However, it should be noted that the application of calcium propionate in the medical field needs to be carried out under the guidance of a doctor to ensure its safety and effectiveness.

4. Safety

As a safe and reliable food additive and feed mildew inhibitor, the safety of calcium propionate has been widely recognized. Many studies have shown that calcium propionate has no toxic effects on humans and animals within the prescribed range of use, and will not accumulate in the body to produce toxicity. At the same time, calcium propionate can also be metabolized and absorbed by humans and animals normally to supply the necessary calcium. Therefore, the application of calcium propionate in food, feed and pharmaceutical industries is safe and reliable.

5. Summary

In summary, calcium propionate is a chemical substance with wide application value. In the food industry, it plays an important role as a mildew inhibitor and nutritional additive; in the feed industry, it is an important substance to prevent feed mildew and provide calcium; in the pharmaceutical industry, calcium propionate also has certain application value. At the same time, the safety of calcium propionate has been widely recognized, and its application prospects are very broad. However, when using calcium propionate, it is still necessary to pay attention to comply with relevant regulations and standards to ensure its safety and effectiveness.
