Fumaric acid

Fumaric acid is a colorless, crystalline organic compound that has a slightly sour taste. In its pure form, fumaric acid is typically odorless, but when dissolved in water, it can have an acidic taste. It is most commonly found in nature as a byproduct of the citric acid cycle, which occurs in the mitochondria of cells, and is a critical compound in the generation of energy.

Properties 

• Acidulant and Preservative: Fumaric acid is used in food products as an acidulant, providing a tart flavor. It’s commonly found in beverages, confectionery, and baked goods. It helps to preserve food by lowering pH and inhibiting microbial growth.
• Enhancing Stability: In foods, fumaric acid can help stabilize flavors, prevent spoilage, and extend shelf life.
• Stability: Fumaric acid is stable at room temperature, making it easy to store and handle. It’s relatively resistant to heat and chemical degradation.
