Details:

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. In fumaric acid the carboxylic acid groups are trans (E) and in maleic acid they are cis (Z). Fumaric acid has a fruit-like taste. The salts and esters are known as fumarates. Fumaric Acid is in the shape of colorless crystal, existing in many kinds of mushrooms and fresh beef. 

Fumaric Acid can be used in the manufacturing of unsaturated polyester resins. Fumaric Acid is a food acidulent used for a long time because it is non-toxic. As a food additive, Fumaric Acid is an essential food ingredient in our food supply. As a leading food additives and food ingredients supplier in China, we can provide you with high quality Fumaric Acid.

Application:

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.

1. Food

Fumaric acid has been used a food acidulant since 1946. It is approved for use as a food additive in the EU, USA and Australia and New Zealand. As a food additive, it is used as an acidity regulator and can be denoted by the E number E297. It is generally used in beverages and baking powders for which requirements are placed on purity. It is generally used as a substitute for tartaric acid and occasionally in place of citric acid, at a rate of 1 g of fumaric acid to every ~1.5 g of citric acid, in order to add sourness, similarly to the way malic acid is used. As well as being a component of some artificial vinegar flavors, such as "Salt and Vinegar" flavored potato chips, it is also used as a coagulant in stovetop pudding mixes.

2. Medicine

In patients with relapsing-remitting multiple sclerosis, dimethyl fumarate (BG-12, Biogen) significantly reduced relapse and disability progression in a phase 3 trial. It activates the Nrf2 antioxidant response pathway, the primary cellular defense against the cytotoxic effects of oxidative stress.

3. Other uses

Fumaric acid is used in the manufacture of polyester resins and polyhydric alcohols and as a mordant for dyes.
