Description

Description générale

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. 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. Propionic acid is an excellent raw material as it is stable, cheap and safe and can even be used as a food additive.

Application

Propionic acid has been used as a standard for the gas chromatogrsphic (GC) analysis of short chain fatty acids obatined from Lactobacillus reuteri SK24.003 and α-D-glucan.
