Uses
Fumaric Acid is an acidulant that is a nonhygroscopic, strong acid of poor solubility. it has a solubility of 0.63 g in 100 ml of distilled water at 25°c. it dissolves slowly in cold water, but if mixed with dioctyl sodium sulfosuccinate its solubility improves. the solubility rate also increases with smaller particle size. a quantity of 0.317 kg of can replace 0.453 kg of citric acid. it is used in dry mixes such as desserts, pie fillings, and candy. it is used in dry bever- age mixes because it is storage stable, free flowing, and nonhygro- scopic. it functions as a synergistic antioxidant with bha and bht in oiland lard-base products. in gelatin desserts, it improves the flavor stability and increases shelf life and gel strength.
