Butyric acid

sku: buty-ac

Butyric acid (from Greek βούτῡρον, meaning "butter"), also known under the systematic name butanoic acid, abbreviated BTA, is a carboxylic acid with the structural formula CH3CH2CH2-COOH. Salts and esters of butyric acid are known as butyrates or butanoates. Butyric acid is found in milk, especially goat, sheep and buffalo milk, butter, parmesan cheese, and as a product of anaerobic fermentation (including in the colon and as body odor). It is also found in milk chocolate produced by the Hershey process, or added to imitate the flavour of Hershey's chocolate. Butyric acid is present in, and is the main distinctive smell of, human vomit. It has an unpleasant smell and acrid taste, with a sweetish aftertaste similar to ether. Mammals with good scent detection abilities, such as dogs, can detect it at 10 parts per billion, whereas humans can only detect it in concentrations above 10 parts per million.
