Fumaric acid is commonly found in nature, in many fruits and vegetables. It is extracted from sugar naturally or by chemical synthesis.

Industrially it appears in the form of a white powder.

What it is used for and where

Food

It was among the oldest food acidifiers and is still widely used as an acidity regulator in foods and beverages. Ingredient listed in the European food additives list as E297, acidulant.
