설명

일반 설명

Propionic acid (PA) is a naturally occurring carboxylic acid, which in its pure state exists as a colorless corrosive liquid with an unpleasant odor. Propionic acid is an excellent raw material as it is stable, cheap and safe and can even be used as a food additive.

Propionic acid is a volatile fatty acid (VFA) formed in the rumen of ruminants by bacterial fermentations.
