Fumaric acid

Fumaric acid (CAS 110-17-8), also designated E297, is a naturally occurring organic acid used commercially as an acidulant, pH regulator, and preservative in food and personal care manufacturing.

Where is Fumaric acid used?

• Food and beverage: acidulant in baked goods, fruit-flavored drinks, and gelatin desserts, with a tart, clean flavor at lower inclusion rates than competing acids
• Dry baking mixes: leavening acid reacting with sodium bicarbonate to control gas release and improve texture
• Food systems: preservative aid inhibiting microbial growth and extending shelf life in dry and semi-moist applications
• Personal care: pH adjuster in rinse-off products and topical formulations where buffering stability across varying temperatures is a priority

Good to know: Its low cost relative to citric and tartaric acid, combined with high acidity efficiency at low use levels, makes it a practical choice for formulators managing performance and input costs.

Commercial specifications

• Technical-grade material is available for non-food industrial applications requiring less purity
