Propionic acid fermentation

Propionic-acid fermentation. The main products of propionic fermentation, which is caused by several species of bacteria of the genus Propionibacterium, are propionic acid (CH 3 CH 2 COOH), acetic acid, and CO 2. The chemistry of such fermentation varies greatly depending on circumstances.

Propionic acid

Propionic acid is a naturally occurring carboxylic acid with chemical formula CH3CH2CO2H. It is a liquid with a pungent and unpleasant smell somewhat resembling body odor. The anion CH3CH2CO2− as well as the salts and esters of propionic acid are known as propionates or propanoates.

Processing ingredients you'll commonly see are mineral salt 170 (calcium carbonate) and ascorbic acid (food acid 300 or treatment agent 300), otherwise known as vitamin C. Emulsifiers (427e, 481, 471), vegetable gums (412, 461) and amino acid 920 speed up dough handling, help sliced bread retain its shape and extend shelf life by reducing the crystallisation of starch that makes the bread go hard (if

Bread preservative research

Propionic acid and its salts including calcium propionate (the bread preservative, 282) were approved as food additives by the World Health Organisation because propionic acid occurs naturally in the human body and so was assumed to be safe at any dose.
