The Occurrence of Citric Acid
This compound exists in a great variety of fruits and vegetables but undoubtedly is most predominant in citrus fruits, such as lemons, grapefruits and oranges. In these fruits, citric acid can reach concentrations around 8-10% of dry weight, but these values range widely depending on the species and cultivar.
The Role of Citric Acid in Metabolism
Citric acid, or its conjugate citrate, is an essential component participating in various physiological processes, including oxidation of fats, carbohydrate and proteins. As such, it is involved in the production of over 60% of the energy derived from food. In 1953, Hans Adolf Krebs, from the University of Sheffield, was awarded the Nobel Prize in Medicine for the discovery of what is now known as the Krebs Cycle or the Citric Acid Cycle.
Basically, the Citric Acid Cycle is a series of reactions to generate energy in the form of adenosine triphosphate (ATP). In the process, citric acid is the main player as it is consumed and then regenerated to complete the cycle.

What is Citric Acid?
Citric acid is a weak organic acid that is naturally found in citrus and juicy fruits such as lemons, limes, oranges, grapefruit, apples, pears and berries. Although it is often associated with sweet-tasting fruit, citric acid appears as odourless and colourless crystals.
Melting point: 153°C
Boiling point: 175°C
Density: 500-950 kg/m3 CAS No.: 77-92-9
Uses of Citric Acid
Citric acid is used in a wide range of applications, including:
Food flavouring, colouring or preservation. It is also often added to products like ice cream as an emulsifying agent to stop fats from separating
Cleaning and chelating agents, particularly in the home bathroom and kitchen cleaning products. It is also used to remove rust from steel in the industry
Bath bombs, where it reacts with baking soda to release carbon dioxide. This what causes the bath bomb to fizz
Photographic development to neutralize the alkaline developing solutions
pH balancing for pharmaceuticals
Substitution of nitric acid in industry.
Production of Citric Acid
Citric acid at room temperature is a white crystalline powder in either anhydrous or monohydrate forms. Monohydrate citric acid can be easily dried by heating the crystals at 78oC, but higher temperatures will result in decarboxylation. This compound can dissolve in water, ethanol, ether, DMSO and other solvents.
Citric Acid Side Effects
Although it is a weak acid, citric acid can cause adverse effects in humans if inhaled or ingested in large, concentrated quantities over a long-term period. It is crucial that all handling and storage guidelines are properly adhered to at all times regarding this product.
Side effects of consuming too much citric acid include stomach cramps, nausea, diarrhoea or vomiting and increased sweating or swelling.
