Definition Of Citric Acid And Citric Acid Uses
A weak organic acid that has the chemical formula, which is C6H8O7, is known as Citric Acid. It is an intermediate in the citric acid cycle in terms of biochemistry, which generally occurs in the metabolism of all aerobic organisms. Citric Acid uses are considered as very much advantageous. Citric Acid is a natural acid in citrus fruits, tomatoes, and many fruits and vegetables. In many consumer goods, food as well as beverage sectors, citric acid use can be seen. Citric Acid being an acidulant, mainly produced by fermentation and citrate, is a derivative of Citric Acid. Citric acid is used in various industries.

Citric Acid Benefit
Citric Acid forms a broad range of metallic salts along with the complexes with copper, iron, manganese, magnesium, and calcium, which is considered as a Citric Acid benefit. These salts are the reasons for Citric Acid uses as a sequestering agent for anticoagulant blood preservatives as well as industrial processes. It is also the premise of antioxidant properties in fats and oils where it diminishes metal-catalyzed oxidation by chelating hints of metals, such as iron.
There are two segments to its utilization as a seasoning. The first is because of its acidity, which has little trailing sensation, the second to its capacity to improve different flavors. A procedure to expel sulfur dioxide from pipe gases created where citric Acid uses as a scrubber, framing an unpredictable particle that responds with H2S to give natural sulfur recovering citrate. This may turn out to be progressively significant with expanded ecological pressures.
Citric acid esters of the scope of alcohols, the triethyl, butyl, and acetyl tributyl esters are utilized as plasticizers in plastic films, and monostearyl citrate is used rather than citric acid as an antioxidant in oils and fats.

The synthetic properties of citrus extract as feeble organic Acid make it a reliable conditioner for water.
It works by separating the following amounts of metal found in water, making it an ideal all-characteristic choice for hard water treatment.
Citric Acid Industrial Uses
Industrial acetic acid uses soap manufacturing, detergent manufacturing, electroplating, and leather tanning.
Citric Acid is used as a preservative for stored blood and a buffer and antioxidant in the pharmaceutical and cosmetic industries.
Full ranging application in citric Acid in food, feed, pharmaceutical, and polymer industries has been found by the several fungal derived acids having commercial value.
A citric Acid is an enormous number of metabolites delivered by Aspergillus species. The citric acid sum in vegetables and natural products additionally differs with different soil and climate.
Fun Facts
In 1782, Carl Wilhelm Scheele was the first who could extract citric Acid from lemons.
Though not an antioxidant itself, citric Acid enhances the activity of many beneficial antioxidants as a citric acid benefit.
FAQs on Uses of Citric Acid
1. What is citric acid and what is its chemical formula?
Citric acid is a weak organic acid naturally found in citrus fruits like lemons and oranges. It is a key intermediate in the metabolism of almost all living things. As a white crystalline powder, its chemical formula is C₆H₈O₇. It is widely used commercially as a natural preservative and flavouring agent.
2. What are the main uses of citric acid in the food and beverage industry?
In the food and beverage industry, citric acid serves multiple important functions:
- Flavouring Agent: It provides a sour, tart taste to soft drinks, candies, and other food items.
- Preservative: It increases the acidity (lowers the pH) of food products, which helps inhibit the growth of bacteria and mould, extending shelf life.
- Acidulant: It is used to control the acidity and pH levels in products like jams, jellies, and canned goods.
- Emulsifier: In products like ice cream, it helps keep fat globules separated, preventing crystallisation and ensuring a smooth texture.
3. How is citric acid powder used as an effective cleaning agent at home?
Citric acid powder is an excellent eco-friendly cleaning agent due to its ability to act as a chelating agent. It effectively breaks down mineral deposits and is used for:
- Descaling: Removing limescale from kettles, coffee machines, and boilers by reacting with the calcium carbonate buildup.
- Water Softening: It binds with metal ions in hard water, making detergents and soaps more effective.
- Removing Soap Scum: It helps dissolve soap scum and hard water stains on bathroom tiles and glass screens.
4. Why is citric acid a common ingredient in cosmetic and skincare products?
Citric acid is used in cosmetics for several key reasons. As an Alpha-Hydroxy Acid (AHA), it helps exfoliate the top layers of skin, promoting skin cell turnover and improving skin tone. It also functions as:
- A pH adjuster to ensure the product's acidity is stable and safe for the skin.
- An antioxidant that helps protect the skin from free radical damage and enhances the stability of other ingredients in the formula.
5. What role does citric acid play in the pharmaceutical industry?
In pharmaceuticals, citric acid is a versatile ingredient used as an excipient (an inactive substance that serves as the vehicle for a drug). Its primary roles include:
- Buffering Agent: It helps maintain a stable pH in liquid medicines and syrups.
- Anticoagulant: Citrate salts are used to bind calcium ions in blood, preventing clotting in stored blood samples.
- Flavouring: It is used to mask the unpleasant taste of some active pharmaceutical ingredients, especially in chewable tablets and syrups.
6. How does citric acid's ability as a chelating agent explain its use in both cleaning and food preservation?
Chelation is the process where a chemical compound, like citric acid, binds tightly to metal ions. This single property explains two different uses:
- In Cleaning: It chelates calcium and magnesium ions found in hard water and limescale. By binding to these metal ions, it dissolves the mineral buildup, making it an effective descaler.
- In Food Preservation: It chelates trace metal ions (like iron and copper) that can catalyse the oxidation of fats and vitamins, which leads to spoilage and rancidity. By deactivating these metals, citric acid acts as an antioxidant synergist, extending the freshness and stability of food.
7. Beyond its commercial uses, what is the biological importance of citric acid in living organisms?
Citric acid is fundamental to life itself. Its biological importance lies in its central role in the Citric Acid Cycle, also known as the Krebs Cycle. This metabolic pathway occurs inside the mitochondria of cells in all aerobic organisms, including humans. In this cycle, citrate (the ionised form of citric acid) is a key intermediate molecule that is broken down in a series of steps to produce ATP (adenosine triphosphate), the main source of energy for cellular processes.
8. Is citric acid safe to consume, and how does it differ from acetic acid or ascorbic acid?
Yes, citric acid is recognised as Generally Recognized As Safe (GRAS) by food safety authorities worldwide for consumption in normal amounts. It is different from other common acids:
- vs. Acetic Acid: Acetic acid is the primary component of vinegar. While both are weak acids used in food, citric acid is a solid with a fruity, tart flavour, whereas acetic acid is a liquid with a distinct pungent smell and sharp taste.
- vs. Ascorbic Acid: Ascorbic acid is the chemical name for Vitamin C, an essential nutrient and powerful antioxidant. While citric acid also has antioxidant properties, its main roles in food are as a preservative and flavouring agent. They are chemically different and serve different primary functions.
