CAS No: 110-17-8
Chemical Name: trans-butenedioic acid
Molecular Formula: C4H4O4
Molecular Weight: 116.07
Chemical Structural:

Fumaric acid is one of two isomeric unsaturated dicarboxylic acids, the other is maleic acid wherein the carboxylic acid groups are cis-. The cis- isomer is the less stable than trans- isomer.
Fumaric acid, an organic acid, has bacteriostatic and antiseptic function. It is used as acidulant, acidity regulator, acidifier, thermal-oxidative resist auxiliary, curing accelerant and spice in food and beverage products, such as in tortillas and breads, fruit juice and nutraceutical drinks, wine, confectioneries, jellies and jams, desserts.
