Acetic acid

Acetic acid is a weak acid, and the defining ingredient in vinegar. Aside from its common use in food, acetic acid is an important industrial chemical.

Production

Biological Synthesis

Since prehistoric times, humans have produced acetic acid by exposing alcoholic beverages to aerobic bacteria usually of the acetobacter genus. The bacteria convert the alcohol to acetic acid. Distillation of the vinegar concentrates the acid.

There is a critical shortage of informative atrclies like this.

Use

Food Preservation

Though acetic acid is commonly generated by certain microbes, in high enough concentrations it preserves food.

I really couldn't ask for more from this aritlce.
