Sodium sorbate

A chemical compound used as a preservative

Sodium Sorbate

Structural formula of sodium sorbate

Sodium sorbate is a chemical compound with the formula C_H_NaO_. It is the sodium salt of sorbic acid, a naturally occurring compound that is widely used as a preservative in the food industry. Sodium sorbate is known for its ability to inhibit the growth of mold, yeast, and fungi, making it an effective preservative for a variety of food products.

Chemical Properties

Sodium sorbate is a white, crystalline powder that is soluble in water. It is stable under normal conditions but can decompose when exposed to heat or acidic conditions. The compound is often used in its salt form because it is more soluble in water than sorbic acid itself.

Uses

Sodium sorbate is primarily used as a food preservative. It is commonly added to products such as cheese, baked goods, and beverages to extend their shelf life by preventing spoilage caused by microorganisms. In addition to its use in food, sodium sorbate is also used in cosmetics and pharmaceuticals to prevent microbial contamination.

Mechanism of Action

The preservative action of sodium sorbate is due to its ability to disrupt the cell membranes of microorganisms, thereby inhibiting their growth and reproduction. It is particularly effective against molds and yeasts, which are common spoilage organisms in food products.

Safety and Regulations

Sodium sorbate is generally recognized as safe (GRAS) by the Food and Drug Administration (FDA) and is approved for use in many countries around the world. However, like all food additives, its use is regulated to ensure that it is used in safe amounts. Excessive consumption of sodium sorbate can lead to adverse health effects, although such occurrences are rare.

Related Compounds

Sodium sorbate is related to other sorbate salts, such as potassium sorbate, which is also widely used as a preservative. These compounds share similar properties and uses, although their solubility and effectiveness can vary.
