General description

Propionic acid (PA) also known as propanoic acid is a short chain fatty acid mainly used as food preservative.[1] It is one of the main metabolic end product formed during the fermentation of undigested food in the colon by the microbiota.[2] Its manufacture by glycerol/glucose co-fermentation using Propionibacterium acidipropionici has been reported.[3] Crystal structure study reveals that PA crystals are monoclinic with space group P21/c.[4]
Propionic acid (PA) is a naturally occurring carboxylic acid, which in its pure state exists as a colorless corrosive liquid with an unpleasant odor. It is miscible in water. Industrially it is produced by hydrocarboxylation of ethylene in presence nickel carbonyl as a catalyst.[5] PA has been found to reduce food intake, lower the fatty acids content in plasma and liver, might improve tissue insulin sensitivity and exerts immunosuppressive actions.[6] Propionic acid is an excellent raw material as it is stable, cheap and safe and can even be used as a food additive.[7]

Application

Propionic acid may be used to alter limestone in order to increase its ability of CO2 uptake.[8]
