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 special sour taste, strong sour taste, is an important organic chemical raw material, is also an intermediate of fine chemical products,but also an important derivative of maleic anhydride, widely used in food, paint, resin, plasticizer fields.

Packaging and Delivery
Application
Mainly used in food for processing meat and fish products. Fumaric acid can be used as an acidity regulator, acidifier, antioxidant additive, pickling promoter, and spice. This product has a strong buffering effect to maintain the aqueous solution at around pH 3.0 and plays an important role in antibacterial and mold prevention. At the same time, it has an astringent taste and is one of the strongest solid acids with a low absorption rate, which helps to extend the shelf life of powder products and other products. When fumaric acid becomes sodium fumarate, its water solubility and flavor are better.

Chemical Property
The simplest unsaturated dicarboxylic acid. It was first discovered in Yanhusuo and also found in various mushrooms and fresh beef. Trans butyric acid and maleic acid are geometric isomers of each other, and trans butyric acid is transformed into maleic acid when heated to 250-300 ℃.
Trans butenedioic acid can also generate monobasic and binary esters or amides, but cannot generate monobasic acyl chloride. It reacts with phosphorus pentachloride or thionyl chloride to form binary acyl chloride. Trans butyric acid is oxidized by potassium permanganate to form racemic tartaric acid.
