 Application

Descriptions:

  • Fumaric acid is a colorless crystalline solid.

  • Fumaric acid is the simplest unsaturated dicarboxylic acids.

  • Combustible, though may be difficult to ignite.

  • The primary hazard is the threat to the environment. Immediate steps should be taken to limit spread to the environment.

Uses:

  • Fumaric acid used as a seasoning.

  • Fumaric acid is also as an antioxidant, mordant (a substance that helps the dye adhere to fabric), and as a buffer.

  • Fumaric acid is used to lower the pH. This helps to a certain degree of anti-microbial agents.

  • Fumaric acid break the bread dough the elastic protein gluten of the sulfur-sulfur bond. It is in the use of rye bread and yeast, making them more acid. Fumaric Acid combined with leavening agent to create slow.

  • Fumaric acid also used to produce unsaturated polyester resins.
