| State | Fumaric acid has a long-lasting sour taste and is much more acidic than citric acid. |
It is mainly used in the processing of meat products and fish products in food. Fumaric acid can be used as an acidity regulator, acidifier, antioxidant assistant, curing accelerator, and spice. This product has a strong buffering effect to keep the aqueous solution at about pH 3.0 and plays an important role in bacteriostasis and mold prevention. At the same time, it has an astringent taste and is one of the strongest solid acids with the strongest sour taste. Its low absorption rate helps to extend the storage period of powder products. When fumaric acid is changed into sodium fumarate, its water solubility and flavor are better.
1. Used in the manufacture of unsaturated polyester, sour agents, and amino acids.
2. Food acidulant.
3. It is also used in the production of unsaturated polyester resin.
