Acetic acid

E260

Acetic acid is a weak organic acid that gives vinegar a distinctive sour taste and pungent odor.

Clean, water-free acetic acid (“ice” acetic acid), is a colorless, hygroscopic liquid that absorbs water from the environment and freezes already at 16,5°C in a colorless crystal.

Concentrated acid solution is very corrosive. Concentration of 80 % is most common.

In food industry, it is used in production of soft drinks in bottles and as a regulator of acidity and spice.

Diluted acetic acid produced by fermentation is called natural vinegar.
