Fumaric Acid
CAS Number: 110-17-8
Fumaric acid is a trans-butenedioic acid used as an acidulant and leavening acid in baked goods, beverage dry mixes, and wine. Its very low solubility at room temperature and delayed dissolution at baking temperatures make it ideal for slow-acting leavening systems. Fumaric acid provides the highest equivalent acidity per gram of any food-grade acidulant (0.89 vs. 1.00 for citric acid on acid equivalence).
