Fumaric acid or trans-butenedioic acid , is the chemical compound with the formula HO2CCH=CHCO2H.
This white crystalline compound is one of two isomeric unsaturated dicarboxylic acids, the other being maleic acid, wherein the carboxylic acid groups are cis. It has a fruit-like taste. The salts and esters of fumaric acid are known as fumarates.
Fumaric acid, when added to food products, is an Acidity Regulator denoted by E number E297
Fumaric acid has bacteriostatic and antiseptic function. It can be used as acidulant, acidity regulator, acidifier, thermal-oxidative resist auxiliary, curing accelerant and spice. Widly used in producing various carbonic acid drink, wine, concentrated solid drink, Ice cream and other cold foods and drink. It can replacemalic acid, citric acid, for its acidity degree is 1.5 times of that of citricacid. Fumaric acid can be used as pharmaceutical intermediate and optical bleachingagent, also used in manufacturing unsaturated polyester resin.
