Application
1.Food usage
In the food industry, fumaric acid is primarily used as an acidulant, a compound that increases acidity. Fumaric acid is included in many common beverages, wines and candies. As an inexpensive and nontoxic compound, fumaric acid is an ideal candidate for everyday food items that extend across multiple categories. Examples include tortillas, English muffins, jelly, pie filling and egg-white foams. Fumaric acid has also been used in animal stock feeds.
2. Medical usage
Fumaric acid is produced naturally by human skin exposed to ultraviolet radiation, such as in sunlight. However, people with psoriasis cannot naturally produce a sufficient quantity of this important compound. Small doses of fumaric acid esters are used to alleviate and treat this condition, according to Kimberly Pryor, writing on the Vitamin Research Products website. Researchers in the pharmaceutical industry are currently investigating fumaric acid as a possible treatment of multiple sclerosis. Fumaric acid is also used to treat rare conditions such as fumaric aciduria, which occur when the body does not produce enough of this compound to properly metabolize food.
3.Industry usage
Fumaric acid finds several key industrial applications. It plays a role in the manufacture of unsaturated polyester resins. Alkyd resins also use this compound in their preparation. Both kinds of resins are used in the construction and automotive industries. Paper sizing requires fumaric acid to increase resistance to liquid absorption. Higher quality papers use higher concentrations of this compound. Additional uses for fumaric acid in industry include use in lubricating oils, plasticizers and as a carboxylating agent for rubber.
