Description

Fumaric Acid:

1. Introduction:
* 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 [= (Z)].
* Fumaric acid, 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 E**7.

2. Usages:
1). Fumaric acid, is used as a flavoring, because it is the sourest tasting of the organic acids. Three parts of fumaric acid are as sour as five parts of citric acid.
2). Fumaric acid, is also used as an anti-oxidant, as a mordant (a substance that helps dyes stick to fabric), and as a buffering agent (helps maintain a particular acidity or alkalinity).
3). Fumaric acid, is used to lower the pH (make something more acid, and thus taste more sour). This helps certain anti-microbial agents such as and work better. Fumaric acid itself kills bacteria also.
4). Fumaric acid, breaks the sulfur-to-sulfur bonds in the elastic protein gluten in bread doughs. This makes the doughs more machineable. It also is uses in rye and sourdough breads to make them more sour.
5). Fumaric acid, is used in combination with to create delayed action leavening agents (something that produces carbin dioxide gas to make breads rise). Since it only dissolves in warm water, the leavening action is delayed until the bread starts to bake.
6). Fumaric acid, is also used in manufacturing unsaturated polyester resin.
