What Is Fumaric Acid?

You might ask what fumaric acid is and where it comes from. Fumaric acid is a kind of organic acid found in nature. Some plants, like fumitory and mushrooms, have small amounts of it. Lichens also contain a little fumaric acid. Your body uses fumaric acid in the citric acid cycle. This cycle helps your body make energy.

Most food grade fumaric acid is made in labs. Scientists use safe ways to make it, like chemical synthesis or fermentation with fungi. The result is a pure, white powder that has no smell. It tastes very sour. You can look at the table below for more facts about its structure and properties:

AspectDetails
Chemical StructureTrans-butenedioic acid (C4H4O4); double bond between two carbons, each with a carboxyl group (-COOH).
Physical PropertiesColorless to white, odorless crystalline powder; tart, acidic-sour flavor stronger than citric acid.
Natural OccurrenceFound in plants (fumitory, mushrooms, lichen), Iceland moss, and some animal tissues.
Industrial OriginMainly produced synthetically for food and beverage use.
Usage in BeveragesUsed as a food acidulant (E297) for sourness and pH regulation; valued for bubble durability and stability in dry mixes.
Additional NotesPart of the citric acid cycle; used as a food acidulant since 1946; FDA recognized as safe.

Uses in Beverages

Food grade fumaric acid is often used in drinks. It helps control acidity and makes flavors stronger. Here are some reasons why companies put it in drinks:

  • It lowers the pH and makes drinks more acidic. This makes drinks taste fresh.
  • It adds a sour, tart flavor that many people like.
  • It helps keep drinks safe by stopping germs from growing. It also keeps the taste the same.
  • Food grade fumaric acid can take the place of other acids. It is stronger than citric acid, so you need less of it.

You can find fumaric acid in many drinks. Some examples are:

  • Soft drinks and sodas
  • Fruit juices and fruit juice drinks
  • Nutraceutical beverages
  • Wine, where it stops unwanted fermentation and keeps the taste clear

Tip: Fumaric acid works well in fruit juice drinks. It gives more sourness per gram than other acids. It also helps keep the color and flavor steady when the pH is near 3.0.

Drink makers like to use food grade fumaric acid. It helps control acidity and makes drinks taste better. You can feel safe when you see it on a drink label.

Food Grade Fumaric Acid Safety

Regulatory Status

You might wonder how food grade fumaric acid gets in your drinks. Food safety groups in many countries check it first. The FDA in the U.S. says food grade fumaric acid is “Generally Recognized as Safe” (GRAS). This means experts agree it is safe in food and drinks if you follow the rules.

In Europe, the EFSA also approves food grade fumaric acid. You will see it as E297 on ingredient lists. This E number means it is an allowed food additive. Australia, New Zealand, China, and Taiwan also let companies use food grade fumaric acid in foods and drinks.

Note: The E number E297 shows food grade fumaric acid passed tough safety checks. It is safe to use in foods and drinks in many places.

Food grade fumaric acid must be very pure. You can see how food grade and industrial grade fumaric acid are different in the table below:

Specification AspectFood Grade Fumaric AcidIndustrial Grade Fumaric Acid
Purity (Assay)High purity, typically 99.5% ~ 100.5%Lower purity requirement
ComplianceMeets food safety standards (FDA, EU regulations)Meets industrial standards, less strict safety
UsageFood and beverage applications (acidulant, antioxidant, pH regulator)Industrial applications (resins, polyesters, coatings, plasticizers)
Safety CriteriaStrict limits on heavy metals, microbial contamination, and impuritiesLess stringent safety standards, not for human consumption
Heavy Metals (Pb, As)Pb ≤ 2 ppm, As ≤ 2 ppmNot specified, but generally higher allowable limits
Microbial LimitsTotal plate count ≤ 1000 cfu/g, molds and yeast ≤ 100 cfu/g, E.coli and Salmonella negativeNot applicable or less strict

You should always pick food grade fumaric acid for drinks. This kind follows strict rules for safety and purity. Industrial grade fumaric acid is not safe to eat or drink.

GRAS and Global Approvals

You can trust food grade fumaric acid because it is approved worldwide. The FDA, EFSA, and FSANZ all say it is safe as a food additive. These groups check for heavy metals, germs, and other bad things. They make sure food grade fumaric acid meets the best safety rules.

  • Fumaric acid has the E number E297. This number means it is an approved food additive.
  • Big food safety groups like EFSA, FDA, JECFA, and FSANZ have checked and approved food grade fumaric acid.
  • Safety tests show food grade fumaric acid is safe at the amounts used in foods and drinks. There is no set daily limit because normal use does not hurt you.
  • You will find food grade fumaric acid in many foods and drinks as a flavoring, acidity regulator, and preservative.

Tip: Food grade fumaric acid is also vegan, halal, and kosher. Most people can have drinks with this ingredient.

Food grade fumaric acid is useful and has a good safety record. You can find it in many drinks around the world. Food safety groups keep checking it to make sure it stays safe. For example, EFSA is now looking at new data to review food grade fumaric acid again. This helps keep your food and drinks safe as science and rules change.

You can feel sure when you see food grade fumaric acid on a drink label. It has passed many safety checks and follows strict rules in the U.S., Europe, Australia, New Zealand, and other places. Food grade fumaric acid helps keep your drinks fresh and tasty while meeting the highest safety standards.

Side Effects and Risks

General Safety

You might ask if fumaric acid in drinks has side effects. When used in food and drinks, fumaric acid is not toxic. Scientists say this acid is found in many foods, like grape berries. Your body also makes fumaric acid when it makes energy. The European Union lets drinks have up to 4000 mg/L of fumaric acid. Studies show drinks still taste good at this amount.

Most people do not have problems with drinks that have fumaric acid. Drinking too much can cause a mild upset stomach, gas, or diarrhea. These problems are rare and only happen if you drink a lot more than normal. The U.S. has strict rules for how much of this additive can be in drinks. These rules help keep you safe.

Note: Pure fumaric acid can hurt your skin or eyes. But drinks have only a tiny amount, so you do not need to worry.

Sensitive Groups

Almost everyone can drink beverages with fumaric acid safely. Children, pregnant women, and people with sensitive stomachs should be careful. If you or your child have a sensitive stomach, you might feel a little sick after drinking a lot. This does not happen often, but it is good to know.

If you have allergies or health problems, check the label before you drink something new. Most people do not get allergies from fumaric acid. It is also fine for vegan, halal, or kosher diets.

GroupRisk LevelAdvice
General populationLowSafe at approved levels
ChildrenLowSafe, but avoid too much
Sensitive stomachsModerateWatch for mild stomach upset
AllergiesVery lowNot a common allergen

You can feel sure that drinks with fumaric acid are safe for most people. If you ever feel sick, try drinking less or pick another drink.

Consumer Questions

Natural or Synthetic?

You might wonder if fumaric acid in drinks is natural or made in a lab. Some mushrooms and plants have fumaric acid. But most fumaric acid in drinks is made by companies. There are two main ways to make it. One way uses petrochemicals. The other way uses fungi like Rhizopus oryzae to ferment things like glucose or farm waste. Fermentation uses things that can grow back, so it is better for the planet. This helps keep making fumaric acid good for the environment. Both ways make sure the fumaric acid is pure and safe. The acid helps keep drinks fresh and safe to drink.

Tip: Fumaric acid from fermentation is better for the earth. It uses things that grow back and fits clean-label trends.

Vegan and Allergen Info

If you are vegan or have allergies, fumaric acid is safe for you. It does not have any animal parts or products. Vegans and vegetarians can drink things with fumaric acid. It also meets halal and kosher rules. Many companies get special certificates to show this. Fumaric acid does not have gluten. People with celiac disease can have it without worry.

Here is a quick guide to common questions:
