Applications of Fumaric acid:
Fumaric acid is mainly used in food products for the processing of meat products and fish products. Fumaric acid can be used as an acidity regulator, an acidifier, an antioxidant builder, a curing accelerator, and a fragrance. This product has a strong buffering effect to keep the aqueous solution at pH 3.0, and has an important effect on bacteriostatic and mildew resistance. At the same time, it has astringent taste and is one of the strongest acid acids, with low absorption rate and help. Extend the shelf life of powdered products, etc. When fumaric acid is changed to sodium fumarate, the water solubility and flavor are better.
