The difference between fumaric acid and citric acid in the use of food additives

The difference between fumaric acid and citric acid in the use of food additives

Structurally, citric acid is a tricarboxylic acid compound, and therefore has similar physical and chemical properties to other carboxylic acids. Fumaric acid, also known as fumaric acid, fumaric acid, and corylic acid, has a chemical formula of C4H4O4. It is a carboxylic acid derived from butene and is a colorless, flammable crystal. Rather than being different, the two are more similar.

This passage is going to talk about the followings of fumaric acid and citric acid:

(1) Definition of fumaric acid

(2) Definition of citric acid

(3) What is the difference between citric acid and fumaric acid?


(1) Definition of fumaric acid

Fumaric acid or fumaric acid is a white crystalline compound widely found in nature. Fumaric acid is a key intermediate in the biosynthesis of organic acids in humans and other mammals in the tricarboxylic acid cycle. Fumaric acid is also an essential ingredient in plant life.

Fumaric acid is found in boletus mushrooms, lichens and Iceland moss. Human skin naturally produces fumaric acid under the sun. Fumaric acid is used in the manufacture of medicines, beverages, foods, animal feeds, detergents, unsaturated polyesters, alkyd resins and printing inks. It is the organic food acid with the strongest titratable acidity and acidity.

When used as a food additive, the hydrophobicity of fumaric acid results in long-lasting, long-lasting sourness and flavor effects. The universal compound can also lower the pH with minimal added acidity in products with a pH greater than 4.5. Its low molecular weight makes fumaric acid have a greater buffering capacity than other edible acids when the pH is close to 3.0.

Due to its strength, compared with other organic food acids, less fumaric acid is required, thus reducing the cost per unit weight.


(2) Definition of citric acid

Citric acid is naturally found in citrus fruits, especially lemons and limes. Because of its acidic and sour taste, citric acid is mainly used as a flavoring and preservative, especially in soft drinks and candies. It can also be used to stabilize or preserve medicines, and as a disinfectant for viruses and bacteria. This is what gives them a sour, sour taste. The manufactured form of citric acid is commonly used as an additive in foods, detergents and nutritional supplements. However, this artificially made form is different from the form naturally found in citrus fruits.

The characteristics of citric acid make it an important additive in various industries.

It is estimated that 70% of artificial citric acid is used in food and beverages, 20% in medicines and dietary supplements, and the remaining 10% is used in detergents. Artificial citric acid is one of the most common food additives in the world. It is used to increase acidity, enhance flavor and retain ingredients.

Soda water, fruit juices, powdered beverages, candies, frozen foods and certain dairy products often contain artificial citric acid. It is also added to canned fruits and vegetables to prevent botulism, a rare but serious disease caused by the toxin-produced Clostridium botulinum.


(3) What is the difference between citric acid and fumaric acid?

Fumaric acid is mainly used in the processing of meat products and fish products in food. Fumaric acid can be used as acidity regulator, acidulant, antioxidant assistant, curing accelerator, and perfume. Fumaric acid is more acidic than citric acid, but citric acid has a wider range of applications.

Citric acid and salts are one of the pillar products of the fermentation industry, mainly used in the food industry, such as sour agents, solubilizers, buffers, antioxidants, deodorants, flavor enhancers, gelling agents, toners, etc. . Lemon is widely used in detergent production, and its own specificity and chelation effect play a positive role. In the actual use process, citric acid has a good performance, mainly in terms of safety. The raw materials for preparing citric acid are all derived from food, which is a safe food-grade microorganism. The use of citric acid will not affect the environment. It is relatively easy to degrade under the action of microorganisms and heat. Its own chelating ability is also relatively strong, and the use effect is also relatively prominent. In the field of beauty, citric acid can accelerate the renewal of keratin, and is often used in lotions, creams, shampoos, whitening products, anti-aging products, acne products, etc.
