What is fumaric acid?
Definition and properties
Fumaric acid exists naturally and can also be synthesized artificially. It belongs to the dicarboxylic acid class of compounds. This acid has two opposing carboxyl groups, which makes it more stable. Its molecular formula is C₄H₄O₄, and its structural formula is HOOC-CH=CH-COOH. Fumaric acid is a white powder, readily soluble in water, but also readily soluble in ethanol and ether. It has a high melting point of approximately 287℃, indicating good heat resistance. The fumaric acid molecule is symmetrical and has no dipole moment, therefore it is not optically active. When heated above 200℃, fumaric acid decomposes to form maleic anhydride.
NORBIDAR is a trusted company with over 15 years of experience. They rigorously test fumaric acid, and all their products are food-grade certified. With its advanced technology, NORBIDAR’s products are sold worldwide, making them a reliable supplier for numerous clients.
Common Uses
Fumaric acid has a wide range of uses in everyday life. It is added to food to give it a sour taste, helps keep food fresh, and prevents mold growth in tortillas, bread, juice, and desserts. Fumaric acid also helps control the pH level of food and beverages.
Fumaric acid is used in factories to produce polyester resins. These resins are used in the manufacture of building materials, automotive parts, and marine components. Some cleaning products and dyes also contain fumaric acid. It has applications in many markets.
Fumaric acid is known for its stability and safety, and its applications are wide-ranging. NORBIDAR is committed to providing high-quality products and innovative ideas to customers in the food, construction, and other industries.
Natural sources of fumaric acid
Content in Plants and Fruits
Fumaric acid is found in many plants. It helps plants grow and stay strong. Some fruits are rich in this compound. Cornus officinalis has the highest content of this organic acid. Wild strawberries, rose hips, and blueberries have lower levels of fumaric acid. The table below shows the fumaric acid content of each fruit:
| Fruit Species | Total Organic Acid Content (g kg−1) | Fumaric Acid Influence | Other Organic Acids Influence |
|---|---|---|---|
| Cornus officinalis | 36.30 to 48.4 | Significant | Significant |
| Wild Strawberry | 4.53 to 9.22 | No significant influence | Shikimic acid content significant |
| Rosehip | 5.87 to 12.74 | N/A | N/A |
| Bilberry | 9.78 to 15.16 | N/A | Significant |
Vegetables also contain fumaric acid. Radishes are rich in it, mainly found in their leaves and stems. Lichens and mushrooms also contain fumaric acid. This compound exists naturally in plants. Plants produce fumaric acid during metabolism. They use the tricarboxylic acid cycle (TCA cycle) to synthesize fumaric acid. The following are the steps in which plants synthesize fumaric acid:
- Pyruvate goes into the TCA cycle after glycolysis.
- Acetyl-CoA joins with oxaloacetate to make citrate.
- Citrate changes into isocitrate.
- Isocitrate becomes α-ketoglutarate and gives off energy.
- α-Ketoglutarate turns into succinyl-CoA.
- Succinyl-CoA changes into succinate, then fumarate.
- Fumarate hydrates and forms fumaric acid with fumarase.
This process provides energy to plants and helps them build molecules. Fumaric acid in plants contributes to their survival and growth.
Biological Presence in Humans and Organisms
Fumaric acid is essential to organisms. It is a component of the tricarboxylic acid cycle (TCA cycle), which produces energy within cells. Humans and animals need this cycle to obtain energy from food. The table below shows the role of fumaric acid in the body:
| Biological Function | Description |
|---|---|
| TCA Cycle Intermediate | Fumaric acid forms from succinate by succinate dehydrogenase. |
| Energy Production | It helps generate reducing equivalents like FADH₂ and NADH for ATP synthesis. |
| Anaplerotic Reactions | Fumarate participates in reactions that replenish TCA cycle intermediates. |
| Metabolic Disorders | Problems with fumarate metabolism can cause fumarase deficiency syndrome. |
Cells use fumaric acid to maintain energy stability. It helps replenish important molecules in the tricarboxylic acid cycle (TCA cycle). Health problems can arise if the body cannot properly utilize fumaric acid. Human skin also produces fumaric acid after sun exposure. This natural compound helps maintain the metabolic health of many organisms, such as lichens and mushrooms.
Fumaric acid is essential for life. It contributes to energy production and maintains metabolic balance in plants, humans, lichens, and mushrooms.
Synthetic production of fumaric acid
Industrial Production Methods
Fumaric acid is synthesized in factories using various methods. The most common method is chemical isomerization. In this process, maleic acid is converted to fumaric acid. Heating or a catalyst facilitates this conversion. This method can produce large quantities of fumaric acid and is well-suited for mass production. Another method is biosynthesis. Certain microorganisms can convert glucose or other carbohydrates into fumaric acid. This method is more time-consuming and produces less fumaric acid than chemical isomerization.
The table below lists several major methods and their yields:
| Method | Yield (%) | Notes |
|---|---|---|
| Chemical Isomerization | >80 | High yield, established method for industrial production of fumaric acid. |
| Biosynthesis | <31 | Generally low yield and efficiency, longer production cycle. |
Factories choose production methods based on cost, speed, and demand. Chemical isomerization is the preferred method for most companies because it produces more fumaric acid faster.
Raw materials are crucial to fumaric acid production. The primary raw material is maleic anhydride, derived from the oxidation of n-butane. Factories can also use maleic acid, which can be produced from maleic anhydride. Glucose and other carbohydrates are used in fermentation. The table below lists commonly used raw materials and their sources:
| Raw Material | Source/Process |
|---|---|
| Maleic Anhydride | Derived from the oxidation of n-butane |
| Maleic Acid | Produced through catalytic isomerization of maleic anhydride |
| Glucose/Carbohydrates | Used in fermentation processes |
This method produces synthetic fumaric acid that meets stringent quality standards. Companies like NORBIDAR use advanced equipment to ensure its purity and safety.

Uses of fumaric acid
Food and Beverage Applications
Fumaric acid plays an important role in food production. Companies add it to foods to alter their flavor and control acidity. This compound gives baked goods, candies, and beverages their tangy flavor. It helps maintain the pH stability of fruit juices and soft drinks. Fumaric acid is a preservative that extends the shelf life of food and prevents spoilage. Agencies such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) consider fumaric acid safe for consumption and have established regulations regarding its usage in various foods.
- Makes rye bread, tortillas, and sourdough taste more sour.
- Adds acid to candy and jelly, so they last longer.
- Makes jams and jellies firmer, so less gelatin is needed.
- Used in dry mixes, dairy foods, and meats.
Animal Nutrition and Feed
Farmers add fumaric acid to animal feed. Fumaric acid lowers the pH level in the stomach, helping animals better utilize digestive enzymes and thus absorb more protein and nutrients from their food. In addition, fumaric acid helps inhibit diarrhea and the growth of harmful bacteria in animals. Fish, chickens, pigs, and other animals are suitable for consuming fumaric acid.
| Benefit | Description |
|---|---|
| Growth Performance | Nile tilapia grow better when they eat food with fumaric acid. |
| Feed Efficiency | Fish use their food better and get more protein. |
| Gut Health | There are fewer bad bacteria in the gut, so animals are healthier. |
Fumaric acid helps animals grow and stay healthy. It helps good bacteria live in their stomachs.
Industrial and pharmaceutical uses
Factories use fumaric acid for many things. It is needed to make polyester resins for coatings and strong plastics. Factories also use it to control acid and pH in foods. In medicine, fumaric acid helps keep drugs stable and working well. Drug makers use it in medicine for psoriasis and multiple sclerosis. It also makes creams and lotions last longer and feel better.
