Chemical property
Fumaric acid, also known as fumaric acid and fumaric acid, exists naturally in fumaric acid, mushrooms and fresh beef. The white crystals or crystalline powders of monoclinic crystalline system are acicular, prismatic or leaf shaped. Odorless, with a special sour taste, sour taste, about 1.5 times that of citric acid. The melting point is 287ºC, the boiling point is 290ºC, the sublimation is above 200ºC, the water is lost when heated to 230ºC, and the maleic anhydride is formed, and the DL-malic acid is boiled with water. Soluble in ethanol, slightly soluble in water and ether, insoluble in chloroform. The pH of 3% aqueous solution is 2.0 ~ 2.5, and it has strong buffering performance to maintain the pH of aqueous solution at about 3.0. This product is non-toxic, rat oral LD508000mg/kg.
Product use
Fumaric acid is an important organic chemical raw material, an intermediate of fine chemical products, and an important derivative of maleic anhydride. It is widely used in food, coatings, resins and plasticizers. In the food industry, fumaric acid is used as a sour agent, which can be used in refreshing drinks, Western wine, cold drinks, concentrated fruit juices, canned fruits, pickled vegetables, ice cream. It is an acidic substance used as a gas producing agent for solid drinks, with good bubble persistence and fine product organization.
Precautions for use
(1) This product has a strong buffer effect to keep the aqueous solution at about pH3.0, and has an important role in antibacterial and anticorrosive.
(2) This product has astringent taste, is one of the most acidic solid acids. Because of its low solubility in water, it is rarely used. However, its water absorption is low, which helps to extend the shelf life of powder products.
(3) After this product becomes sodium fumarate, water solubility and flavor are better.
