Description
General description
Propionic acid (PA) also known as propanoic acid is a short
chain fatty acid mainly used as food preservative.[2] It
is one of the main metabolic end product formed during the fermentation of
undigested food in the colon by the microbiota.[1] 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.[6] 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.[7] Propionic
acid is an excellent raw material as it is stable, cheap and safe and can even
be used as a food additive.[8]
Application
Propionic acid may be used to alter limestone in order to
increase its ability of CO2 uptake.[5]
