Determination of Fumaric Acid: Quality and Safety Analysis in Food Products

What is Fumaric Acid?

Chemical Structure: Fumaric acid (C₄H₄O₄) is an unsaturated dicarboxylic acid and is naturally found in the fumaric acid cycle (Krebs cycle).

Natural Sources: Found in low concentrations in fruits and vegetables. It is synthesized naturally, especially in fungal species and some plants.

Use of Fumaric Acid in the Food Industry

Acidity Regulator: Controls the pH level in foods and provides stability.
Preservative: Prolongs shelf life by inhibiting microorganism growth.
Flavoring: Improves the taste profile with its sour taste.
Texture Enhancer: Improves crust formation and consistency in pastries.

Food Products Using Fumaric Acid

Confectionery and chewing gum.
Powdered drink mixes.
Canned fruit and vegetables.
Jellies, jams and marmalades.
Bakery products.
Meat and fish products.

Regulations and Limits

Many countries and international organizations regulate the amount of fumaric acid that can be used in foods. For example:

Codex Alimentarius: Sets maximum limits for the use of fumaric acid in foods.
European Union: Fumaric acid is approved as an additive with the code E297 and its limits of use are set.
Turkey: The Turkish Food Codex contains regulations on the use of fumaric acid.

Legal limits may vary depending on the type of product and intended use.

Confectionery: Maximum 3 g/kg.
Beverages: Maximum 0.5 g/L.

What are the Risks of Excessive Consumption of Fumaric Acid?

Fumaric acid is safe in normal use but can have toxic effects at high doses:

Gastrointestinal disorders, impaired kidney function, digestive system problems due to excessive acidity. To avoid such health risks, fumaric acid should be kept within the limit values in products.

Fumaric acid determination is the analysis used in quality control and safety of food products. Modern analytical methods make it possible to precisely detect fumaric acid and ensure compliance with legal limits. With this analysis, it is aimed to offer safe and quality products to the market for both producers and consumers.
