Is 330 vegan?

In this brief guide, we will answer the query, “Is 330 vegan?” and will discuss the properties of citric acid.

Is 330 vegan?

Yes, 330 is vegan. 330 is also called citric acid and it is vegan because it is obtained from only plant-based products like lemon, lime, oranges, and tomatoes, etc.

One of the most often used acidulants in food and beverage, citric anhydrous or monohydrate, also serves as a preservative, pH buffer, antioxidant and chelating agent. Citric acid anhydrous or monohydrate In the European Union, it is known as E330. In 2019, China shipped almost 1 million tons of citric acid, making it the world’s largest producer.

What is the chemical formula for citric acid?

It is a naturally occurring organic acid that contributes to citrus fruit’s sour flavor. In addition, as an intermediary in the tricarboxylic acid cycle or Krebs cycle, it is critical to the metabolism of the majority of living organisms.

Market types

Both anhydrous and monohydrate citric acid is widely available. When heated above 37 °C, monohydrate may become anhydrous.

Natural sources

There is a significant concentration of citric acid in citrus fruits. Citric acid-rich fruits include:

·         Lemon

·         Lime

·         Pineapple

·         Oranges

·         Tomatoes

·         Strawberries

·         Peaches

·         Apples

·         Grapefruits

·         Blueberries

·         Bananas


Citric acid is abundant in citrus juices like lemon and lime. Lemon juice that is ready to drink has a concentration of roughly 41 mg/kg, whereas concentrates have a concentration of around 31 mg/kg. In lime juice, the concentration is 39 mg/kg and 30 mg/kg, respectively. From 0.62 to 0.96 mg/kg, it is found in commercial lemon juice-based products like lemonade.

How is citric acid made?

Commercially, citric acid is made from corn-derived glucose or sucrose carbohydrate substrates by microbial fermentation. Black mold is often fed a substrate. In the microbial generation of citric acid, the most common organism employed is Aspergillus niger.

The Food and Drug Administration has authorized three methods of manufacturing:

·         From plant sources like citrus, pineapple, and other fruit juices

·         Employing Candida spp. for mycological fermentation.

·         From the fermentation fluid of Aspergillus niger.

The fungus Aspergillus niger has been used to produce 99 percent of the world’s citric acid since 1919, according to research published in Toxicology Reports in 2018. Since the third process approach above is most often employed.



An acidic white crystallized powder or granular.


To indicate the dissociation of acids, we use the notation Pka. As a weak organic acid with three carboxylic acid functional groups, citric acid has PKa values of 3, 14, 4, and 6.39.


pH measures the citric acid solution’s concentration of H+ ions or H3O+ ions. Citric acid concentration and dissociation affect the PH value. Citric acid, at a concentration of 10 mM (0.01mol/L), has a PH value of 2.62.


At 20 °C, anhydrous has a water solubility of 592 g/L. Monohydrates are water-soluble.

organic solvents-Monohydrate is sparingly soluble in ether and just slightly soluble in ethanol when anhydrous.

What are the health advantages of using citric acid?

In addition to preventing kidney stones, citric acid may also improve the health of our skin.

Antioxidants in the body

Human cells may be protected from the harmful effects of free radicals by citric acid.

Prevent kidney stones

By preventing new stone development and breaking down tiny stones at the beginning of their creation, citric acid is good for persons with kidney stones. In addition, the salts calcium citrate and potassium citrate have stone-preventative properties.

Benefits for the skin

In skincare products, citric acid acts as an alpha-hydroxy acid (AHA). In the cosmetics business, AHA is a carboxylic acid with a hydroxyl group attached to the next carbon atom. As a general rule, AHA may enhance skin issues such as reducing fine lines and wrinkles, improving skin texture and tone, and unclogging and cleaning pores.

Common applications of citric acid

In addition to being utilized in food and beverage, pharmaceutical, cosmetic, and water treatment, citric acid may also be employed in home cleaning products because of its versatility.


With malic and tartaric acids, it is a common organic acid used in food. As a preservative, antioxidant, chelating agent, and citric acid for food usage.


Adding a sour taste, enhancing flavor, and adjusting PH are some of the most prevalent uses of citric acid in food and beverage.


This acidic pH makes it ideal for food preservation since many germs are unable to thrive in an acidic environment.


Oxidation may be prevented or slowed down in food if it is present in low amounts.

Chelating agents

The capacity to create chelate complexes with polyvalent metal ions may enhance the quality and stability of meals.

Supplements for health and wellness

As a supplement to meals, it is possible to utilize its derivatives, calcium citrate and iron citrate.


Cosmetic and personal care products use it as a buffering, chelating, and masking agent, according to the “European Commission database for information on the cosmetic chemicals and components.”
