Propionic acid inhibits the growth of mold and some bacteria at levels between 0.1 and 1% by weight. As a result, some propionic acid produced is consumed as a preservative for both animal feed and food for human consumption. For animal feed, it is used either directly or as its ammonium salt. This application accounts for about half of the ...

Members of the genus Propionibacterium are widely used in the production of vitamin B 12, tetrapyrrole compounds, and propionic acid, as well as in the probiotics and cheese industries. [7] The strain Propionibacterium freudenreichii subsp. shermanii is used in cheesemaking to create CO 2 bubbles that become "eyes"—round holes in the cheese. [8]
A preservative is a substance or a chemical that is added to products such as food products, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes.
Citric acid – food acid; Citric acid esters of mono- and diglycerides of fatty acids – emulsifier; Citrus red 2 – color (red) Cloves – Cochineal – color (red) Coconut oil – a cooking oil, high in saturated fat – particularly used in baking and cosmetics.

Propionyl-CoA is a coenzyme A derivative of propionic acid.It is composed of a 24 total carbon chain (without the coenzyme, it is a 3 carbon structure) and its production and metabolic fate depend on which organism it is present in. [1] Several different pathways can lead to its production, such as through the catabolism of specific amino acids or the oxidation of odd-chain fatty acids. [2]
