Description
Fumaric acid is an organic compound with the formula HO₂CCH=CHCO₂H It is a white solid that occurs widely in nature and has a fruit-like taste this compound is used as a food additive and is known by its E number, E297This compound is the trans isomer of butenedioic acid, while maleic acid is the cis isomer.
Application
Fumaric Acid used as a seasoning, because E297 is the organic acid sourest taste. Fumaric Acid three parts are as sour as the five parts of citric acid.
Fumaric Acid but also as an antioxidant, mordant (a substance that helps the dye adhere to fabric), and as a buffer (to help maintain a particular acidity or alkalinity).
Fumaric Acid is used to lower the pH (acid to make more things, which taste more sour). This helps to a certain degree of anti-microbial agents, such as better work. Fumaric Acid itself to kill bacteria.
Fumaric Acid break the bread dough the elastic protein gluten of the sulfur-sulfur bond. This makes the dough more machinable. Fumaric Acid is in the use of rye bread and yeast, making them more acid.
Fumaric Acid combined with leavening agent (carbon dioxide gas produced carbin to make bread rise) to create slow. Because Fumaric Acid is only dissolved in warm water, leavening action postponed to start baking bread.
Fumaric Acid also used to produce unsaturated polyester resins, Fumaric acid fumaric acid formula HO2CCH = CHCO2H compounds. This white crystalline compound of two isomers of the unsaturated dicarboxylic acid, maleic acid, the other one, which carboxylic acid groups of the CIS . Fumaric Acid with fruit flavor.
