E297 – Fumaric Acid
PreservativeDescription
White crystalline powder
Notes
Fumaric acid is a white, crystalline powder that occurs naturally in many plants and vegetables, including mushrooms, lichen, and Iceland moss. While it can be extracted from natural sources, the fumaric acid used in food production is typically made synthetically by converting another organic acid called malic acid through a chemical process. As an acidulant, fumaric acid adds tartness to foods and helps regulate acidity levels, giving products a pleasant sour taste. You'll find it in powdered drink mixes, gelatin desserts, pie fillings, and some baked goods. It's particularly useful in dry mixes because it doesn't absorb moisture from the air as readily as some other acids. Fumaric acid is completely suitable for vegetarians, vegans, and all religious dietary requirements since it contains no animal-derived ingredients. It's generally recognized as safe and doesn't pose allergen concerns for most consumers. Because it occurs naturally in the human body as part of normal metabolism, it's considered a very gentle food additive.
