MAIN FUNCTION AND PURPOSE	Used as an acidulant, Fumaric acid has bacteriostatic and antiseptic function. It also can be used as acidity regulator, acidifier, thermal-oxidative resist auxiliary, curing accelerant and spice. Used as acidic substance of     effervescent agent, it can produce extended and exquisite bubbles.      Fumaric acid can be used as pharmaceutical intermediate and optical bleaching agent. In pharmaceutical industry, it is used to produce alexipharmic sodium dimercaptosuccinate and ferrous fumarate. Fumaric acid is also used in manufacturing unsaturated polyester resin.
