Fumaric Acid (E297)

Fumaric Acid Fumaric acid is manufactured primarily via fermentation of glucose using Rhizopus fungi for natural production or through isomerization of maleic anhydride from petroleum sources for industrial scale. This clean-label organic acid provides sharp acidity (1.5x citric acid), superior solubility in dry mixes, and precise pH control. It offers leavening synergy that enhances fruit flavors, stabilizes emulsions, and extends shelf life through antimicrobial activity. In the food industry, it serves as a cost-effective acidity regulator for beverages and gels, demonstrates rapid dissolution in powdered applications, heat stability up to 200°C, and promotes gelation ideal for low-pH formulations and reduced-acid systems.
