Product Description: Fumaric Acid Product Alias: Fumaric acid is also known as trans-butenedioic acid, boletic acid, and Lichenic acid. Appearance: Fumaric acid is a white crystalline compound. Character: Fumaric acid is a key intermediate in the tricarboxylic acid cycle for organic acid biosynthesis in humans and other mammals. It is a strong organic acid, relatively non-toxic and non-irritant. Category: Fumaric acid falls under the category of carboxylic acids, specifically dicarboxylic acids. It is a naturally occurring substance found in various sources, including lichen and bolete mushrooms.  Product Specifications: Fumaric acid is a stable, non-hygroscopic compound with a molecular formula of C4H4O4. It has a molar mass of 116.07 g/mol and a density of 1.635 g/cm³. It is soluble in alcohol and slightly soluble in water and ether. The melting point of fumaric acid is 287°C (549°F), and it decomposes at 230°C (446°F) under pressure. Industrial Applications: Fumaric acid has a wide range of applications in various industries. It is used in the manufacture of polyester resins, alkyd resins, and as a mordant for dyes. It is also used in the production of printing inks and as a white pigment in paints. Food Industry Applications: In the food industry, fumaric acid is used as a food acidulant due to its sour taste. It is used in beverages, baking powders, and confectionery. It is also used as a preservative in various food products due to its antimicrobial properties. Fumaric acid is often used in conjunction with xanthan gum in the food industry. Xanthan gum is a polysaccharide with a wide variety of uses, including as a stabilizer, thickener, and emulsifier. It is produced by the fermentation of glucose or sucrose by the Xanthomonas campestris bacterium. When used together, fumaric acid and xanthan gum can improve the texture and shelf life of food products. For example, in baked goods, fumaric acid can help to strengthen the gluten network, improving the texture and volume of the product. At the same time, xanthan gum can help to retain moisture, preventing the product from becoming stale. In beverages, fumaric acid can be used to provide a tart, refreshing flavor, while xanthan gum can improve the mouthfeel and stability of the product. This combination is particularly useful in low-calorie or sugar-free beverages, where it can help to enhance the flavor and texture of the product. In conclusion, fumaric acid is a versatile compound with a wide range of applications in various industries. Its combination with xanthan gum in the food industry can provide significant benefits in terms of flavor, texture, and shelf life. Whether used alone or in combination with other ingredients, fumaric acid is a valuable addition to any product formulation.
