E261

Potassium salt of acetic acid, an natural acid, present in most fruits. Produced by bacterial fermentation and thus present in all fermented products. Commercially produced by bacterial fermentation of sugar, molasses or alcohol or by chemical synthesis from acetealdehyde.

Acetates are used as preservatives and buffers.

Typically found in such products as sauces and pickles. Also used as a fabric conditioning agent, and in the manufacture of penicillin.

No side effects, acetates are a normal component of all body cells. Should only be avoided by people who have a (very rare) vinegar intolerance and by people with impaired kidney function as it is known to be a diuretic.
