Fumaric acid is the chemical compound. This white crystalline compound is one of two isomeric unsaturated dicarboxylic acids, the other being maleic acid. Fumaric acid is found in fumitory. Fumaric acid is a food acidulent used since 1946. It is non-toxic. It is generally used in beverages and baking powders for which requirements are placed on purity. Fumaric acid was first prepared from succinic acid.
The chemical properties of fumaric acid can be anticipated from its component functional groups. This weak acid forms a diester, it undergoes additions across the double bond, and it is an excellent dienophile. For teaching experiments designed to measure the difference in energy between the cis- and trans- isomers, a measured quantity of carbon can be ground with the subject compound and the enthalpy of combustion computed by difference.
We come across various research reports talking altogether differently about the same food additive- one says its a safe additive and the others say it is not a safe food additives. Food produced on the large scale that is needed to supply supermarkets and other food shops has to be transported and stored before it is consumed.
Fumaric acid is an organic acid widely found in nature. In humans and other mammals. Fumaric acid is the strongest organic food acid in titratable acidity and in sourness. Bartek Fumaric Acid is made from N-Butane that is oxidised to Maleic acid that is then isomerized to Fumaric acid.
