What it is

Fumaric acid is a naturally occurring organic compound found in fruits like lemons and apples. It is typically produced industrially through chemical synthesis, often involving the hydrogenation of maleic anhydride. It is a white crystalline solid that is sparingly soluble in water.

Why it's used

Fumaric acid is used as an acidity regulator, flavoring agent, and preservative in foods. It provides a tart taste and can help control pH levels, which extends shelf life. It is commonly found in powdered drink mixes, gelatin desserts, and baked goods.

Health notes

Fumaric acid is generally recognized as safe (GRAS) by the FDA for use in food. International bodies like JECFA and EFSA have evaluated fumaric acid and its salts. At typical consumption levels, it is not associated with adverse health effects for most people. Some individuals may experience mild digestive upset at very high intakes.

Allergen info

Fumaric acid is not derived from any of the nine FDA major allergens. It does not contain gluten.
