propionát

Propionate refers to the salt or ester of propionic acid. Propionic acid, also known as propanoic acid, is a short-chain carboxylic acid with the chemical formula CH3CH2COOH. It is a naturally occurring substance found in various fermented foods, such as cheese and yogurt, and is also produced by the human gut microbiota.

In the food industry, propionates are primarily used as preservatives. They are effective against mold and other spoilage organisms, extending the shelf life of baked goods, cheeses, and other food products. Sodium propionate and calcium propionate are the most common forms used for this purpose. These compounds work by inhibiting the growth of undesirable microorganisms, thereby preventing spoilage.

Beyond food preservation, propionate derivatives can also have applications in other fields. For instance, certain propionate esters are used as solvents or in the fragrance industry. In a biological context, propionate is an important metabolic intermediate. It is a product of the fermentation of carbohydrates by gut bacteria and plays a role in energy metabolism. The body can convert propionate into succinyl-CoA, a molecule that enters the citric acid cycle for energy production. Research continues to explore the various roles and potential applications of propionate and its derivatives.
