Preservative Fumaric Acid

Fumaric acid is an organic compound that occurs naturally in some fruits, like plums and apples. It is typically produced industrially through chemical synthesis, often using maleic anhydride. It is a white crystalline solid that is sparingly soluble in water.

Manufacturers add fumaric acid to foods and beverages primarily as an acidity regulator and flavoring agent. It provides a tart taste and can enhance the effectiveness of other preservatives. It is commonly found in powdered drink mixes, gelatin desserts, baked goods, and candies.

Fumaric acid is generally recognized as safe (GRAS) by the FDA for use as a food additive. It has been evaluated by JECFA and EFSA, and both have established acceptable daily intakes for it. At typical consumption levels, it is not associated with adverse health effects. Evidence does not suggest it is carcinogenic or mutagenic.
