White odorless powder or crystalline solid particles, with speical sourness that is as strong as 1.5 times of citric acid.

Fumaric acid is white odorless powder or crystalline solid particles, with speical sourness that is as strong as 1.5 times of citric acid. It is soluble in ethanol (5.76g/100g,30), slightly soluble in water (0.63g/100ml,25) and in ether, and very slightly soluble in chloroform. It has no hygroscopicity, and will sublime at 200. Boiling point: 290 (decompose). It will turn to maleic anhydride at 230, and will generate DL-malic acid if boiled with water

Usage:

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 replace malic acid, citric acid, for its acidity degree is 1.5 times of that of citric acid. Fumaric acid can be used as pharmaceutical intermediate and optical bleaching agent, also used in manufacturing unsaturated polyester resin
