Fumaric Acid (CAS#110-17-8) is a vital organic chemical raw material and core intermediate for fine chemical manufacturing. It is a primary downstream derivative of maleic anhydride, with broad utilization across food processing, coating production, synthetic resin synthesis and plasticizer manufacturing industries.
In the food industry, it acts as a high-performance acidulant for numerous edible products, including carbonated soft drinks, wine, chilled beverages, concentrated fruit juices, canned fruits, pickled vegetables and ice cream. When incorporated into foaming agents for solid instant beverages, it generates uniform and stable foam, optimizing the delicate texture of finished solid drinks.

Product Application of Fumaric Acid#110-17-8
Fumaric Acid features non-hygroscopic property and strong acidity, while possessing relatively low water solubility. Its solubility value in pure distilled water reaches 0.63 g per 100 mL aqueous solution under 25 °C ambient temperature.
This substance dissolves at a slow rate in cold water; its dissolving efficiency can be effectively improved by mixing with dioctyl sodium sulfosuccinate or conducting particle size micronization treatment.
In practical food formulation, 0.317 kg fumaric acid can replace 0.453 kg citric acid to achieve equivalent sour flavor effects.
Additional property supplements: Melting point 287 °C; stable under normal ambient conditions; barely soluble in fats and oils, moderately soluble in ethanol.
