The principal components of pyroligneous acid are acetic acid, acetone and methanol. It was once used as a commercial source for acetic acid. In addition, the vinegar often contains 80-90% water along with some 200 organic compounds.
During the United States Civil War, cooks in the Confederate States of America tried to make up for an increasing deficiency in salt by preserving meat and fish in pyroligneous acid, which was not very effective.
