Where does fumaric acid come from?

Fumaric acid is derived from both natural and synthetic sources. This compound is widely distributed. It can be found in fruits and vegetables such as apples, grapes, berries, tomatoes, and carrots. Fungi such as ‘Rhizopus’, ‘Aspergillus’, and ‘Penicillium’ can also produce fumaric acid in soil. In the human body, fumaric acid helps in energy production. Factories use fermentation and chemical methods to produce fumaric acid to meet growing demand.

Natural Sources of Fumaric Acid

Plants and Fungi

Fumaric acid is found in many plants and fungi. Some plants, such as Arabidopsis thaliana and soybeans, are rich in fumaric acid. Arabidopsis leaves can contain several milligrams of fumaric acid per gram. Sometimes, their fumaric acid content even exceeds that of starch or sugars. This makes these plants very useful to scientists and businesses.

Wild plants can also produce fumaric acid. Corydalis, Iceland moss, and lichens are natural sources. Boletus and button mushrooms are rich in fumaric acid. Button mushrooms have a higher fumaric acid content than other organic acids, which gives them their unique flavor. Iceland moss and lichens grow in harsh environments and are beneficial to the environment.

Fungi play an important role in the natural synthesis of fumaric acid. Rhizopus oryzae, Rhizopus arrhizus, and Rhizopus delemar can all synthesize large amounts of fumaric acid. Their synthesis efficiency is highest when nitrogen content is low. These fungi utilize the reducing tricarboxylic acid cycle (TCA cycle) to efficiently synthesize fumaric acid. The table below lists the fumaric acid synthesis rates of different fungi:

Rhizopus oryzae produces the most fumaric acid. Therefore, it is commonly used in large-scale production in factories.

Note: The fumaric acid content in plants and fungi can vary. This depends on their growing location, weather, and other conditions. For example, the fumaric acid content of blueberries may differ between years and regions.

Fruits and Vegetables

Fruits and vegetables are also sources of fumaric acid. Many foods we eat contain this compound. This means that people frequently obtain fumaric acid from their diet. Here are some foods rich in fumaric acid:

• Apples
• Grapes
• Berry
• Tomatoes
• Carrots

These foods taste delicious and provide the body with important organic acids. The table below shows that apples, tomatoes, and carrots contain fumaric acid:

The fumaric acid content in these foods can vary. Soil, weather, and year all affect its content. Blueberries may have a higher fumaric acid content in some years. The fumaric acid content in wild strawberries typically remains constant.

Fumaric acid imparts a sour taste to fruits and vegetables, adding to the appealing flavor of fresh foods. Consuming these foods provides the body with naturally occurring fumaric acid.

Fumaric Acid Metabolism in the Body

Human Metabolic Pathways

The metabolism of fumaric acid occurs within cells. The body utilizes the Krebs cycle to generate energy. This cycle takes place in the mitochondria, known as the cell’s “powerhouse.” The following steps illustrate the formation of fumaric acid:

• Pyruvate originates from the breakdown of sugars and enters the Krebs cycle.
• Pyruvate is converted to acetyl-CoA.
• Acetyl-CoA combines with oxaloacetate to form citrate.
• Citrate is converted to isocitrate.
• Isocitrate loses carbon dioxide to form α-ketoglutarate.
• α-Ketoglutarate is converted to succinylated CoA.
• Succinylated CoA is converted to succinic acid.
• Succinic acid is converted to fumaric acid.
• Fumaric acid is converted back to fumarate with the help of fumarate enzymes.

These reactions demonstrate how fumarate metabolism is linked to energy. Each step helps cells utilize nutrients and maintain normal metabolic function.

Role in Cellular Energy

Fumarate metabolism contributes to energy production. Succinate dehydrogenase catalyzes the conversion of succinate to fumarate. The table below explains this process:

Then, fumarate is converted to malate. This step is crucial for metabolism because it helps cells generate ATP (the primary energy source). Fumarate metabolism also produces building blocks for other molecules. Cells need these building blocks to grow and repair themselves.

Cells need healthy metabolism to remain strong and active. Fumarate metabolism helps maintain high energy levels, allowing the body to function properly.

Those who understand metabolism understand the importance of fumarate. It maintains the normal functioning of the body’s energy system, helping people maintain daily life.

Industrial Production of Fumaric Acid

Fermentation and Biosynthesis

Factory production primarily uses fermentation and biosynthesis to produce fumarate. They utilize specific fungi, such as *Rhizopus nigricans* and *Rhizopus arrhizus*. These fungi can convert plant sugars into fumaric acid. Scientists discovered this ability in *Rhizopus nigricans* in 1911. By 1938, experts found that *Rhizopus* fungi were the most effective. In 1943, some companies began using a new method called deep aerobic fermentation. This method helped them produce more fumaric acid. Today, approximately 85% of fumaric acid comes from fermentation.

The biosynthetic pathway of these fungi is efficient and environmentally friendly. It uses plant feedstocks instead of fossil fuels, which helps protect the environment and supports green development goals. Many companies now use microbial biosynthesis technology. This method is less polluting and more energy-efficient. The process is as follows:

• Workers provide plant sugars to the fungi.
• The fungi convert the sugars into fumaric acid.
• The plant collects and purifies the fumaric acid for use in the food, pharmaceutical, and industrial sectors.

Fermentation and biosynthesis are green methods for producing fumaric acid. This helps meet the demand for safe and environmentally friendly products.

In recent years, more and more people have favored biosynthesis. High oil prices and concerns about pollution have prompted companies to choose fermentation. This method not only offers high yields but also complies with strict regulations.

Chemical Synthesis Methods

Chemical synthesis is another method for producing fumaric acid. This method uses petroleum-derived maleic anhydride as a raw material. Workers mix maleic anhydride with water to produce maleic acid. This is then heated to 100°C to 250°C. A catalyst helps convert maleic acid into fumaric acid. This step, called isomerization, yields over 80%. Factories have been using chemical synthesis since the 1940s.

Chemical synthesis is used when factories need to rapidly produce large quantities of fumaric acid. This method can produce fumaric acid with high yields and high purity. The steps are as follows:

• Convert maleic anhydride into maleic acid.
• Heat and add a catalyst to produce fumaric acid.
• Purify the product according to industry standards.

The following table lists the quality standards for industrial-grade fumaric acid:

Factory manufacturers must comply with these regulations to use fumaric acid in the food and pharmaceutical industries. High purity ensures personnel safety and guarantees good product performance.

Note: Manufacturing fumaric acid is not easy. Low conversion rates, numerous byproducts, and pH variations increase purification difficulty and costs. New technologies such as chromatography help address these issues and ensure high-quality fumaric acid.

The factory uses both biosynthetic and chemical synthesis methods to produce fumaric acid. Both methods are crucial for meeting global demand. The company places great emphasis on purity, safety, and environmental protection in the production of fumaric acid.
