What You'll Learn
Citric acid is a natural preservative and flavouring agent
Citric acid is a weak, sour-tasting compound that occurs naturally in fruits such as oranges, lemons, and berries. These fruits have a high yield of citric acid, which makes them sour and pungent. Citric acid is used as a preservative in cosmetics, food, and personal care products. It is also used in cleaning products to remove hard water build-up and stains. Citric acid is added to commercial cleaning products to remove hard water build-up on dishes and glassware. It is also used to remove coffee and tea stains, yellowing/browning discolourations, and water and urine stains.
Citric acid is one of the most common food additives in the world. It is used to boost acidity, enhance flavour, and preserve ingredients. It is added to sodas, juices, powdered beverages, candies, frozen foods, and some dairy products. Citric acid is also sometimes added to canned fruits and vegetables to protect against botulism. Citric acid is used to kill harmful bacteria and prevent infections on the skin's surface, which can be common in people with diabetes, the elderly, and those who smoke.
Citric acid is also used in medicines to stabilise and preserve active ingredients. It is added to enhance or mask the taste of chewable and syrup-based medications. Mineral supplements, such as magnesium and calcium, may also contain citric acid to enhance absorption. Citric acid is a versatile additive for food, beverages, medicines, and dietary supplements. It is also used in cleaning and disinfecting products. Citric acid is safe and non-harmful to humans and is recognised as such by the FDA.

Pepsi-Cola in the US contains citric acid
Citric acid is a weak acid found naturally in all citrus fruits. It is colourless and odourless, with a sweet and tart taste. It is also produced naturally in the human body, as it is an important intermediate in metabolism, which is the pathway that allows the body to get energy from carbohydrates, fats, and proteins. Citric acid can also be manufactured artificially and added to food as a preservative or flavouring agent. It is often added to sodas and other soft drinks, including colas, to create a tart taste.
The presence of citric acid in Pepsi-Cola may be surprising to some, as it is believed that the combination of citric and phosphoric acid in soft drinks is extremely damaging to tooth enamel. Excessive consumption of sodas containing these acids can therefore be harmful to oral health. In addition, citric acid may affect blood sugar levels, although studies have found conflicting results, with some showing an increase and others a decrease in blood sugar.
While citric acid is not necessarily healthy and does not add any health benefits to one's diet, consuming it is also not generally considered unhealthy. It is quickly expelled from the body after consumption and is both water-soluble and organic. However, it is important to note that soft drinks, including Pepsi-Cola, that contain high amounts of sugar and acidity can have negative health effects, especially when consumed in large amounts.

Citric acid is found naturally in citrus fruits
Citric acid is a naturally occurring organic acid found in several fruits and vegetables, most notably citrus fruits. Citrus fruits and their juices are the best natural sources of citric acid. The fruits with the highest concentration of citric acid include lemons, limes, and to a lesser extent, oranges and grapefruits. The presence of citric acid gives these fruits their characteristic tart and sour taste.
Citric acid was first isolated in 1784 by the chemist Carl Wilhelm Scheele, who crystallized it from lemon juice. Industrial-scale production of citric acid began in 1890, based on the Italian citrus fruit industry. However, during World War I, the disruption of Italian citrus exports led to the exploration of alternative production methods. In 1917, American food chemist James Currie discovered that certain strains of the mold Aspergillus niger could efficiently produce citric acid from sugar. This microbial production method became the primary industrial route to citric acid, and it is still used today.
Citric acid is commonly added to foods, medicines, supplements, and cleaning agents as a manufactured additive. While the synthetic version of citric acid is generally recognized as safe by the FDA, there have been reports of adverse reactions and allergies in some individuals. These reactions have not been observed with the natural form of citric acid found in citrus fruits.
Citric acid has several health benefits, including aiding in energy metabolism, enhancing the absorption of minerals, and preventing or treating kidney stones. Knowledge of the citric acid content in beverages can be useful in nutrition therapy, especially for patients with hypocitraturia or calcium urolithiasis.
Regarding Diet Pepsi, while I cannot confirm if it contains citric acid, some sources mention that Pepsi contains citric acid, and one source specifically mentions that Diet Pepsi contains phosphoric acid, which is commonly found in dark colas.

Citric acid may affect blood sugar levels
Citric acid is a common ingredient in many soft drinks, including Diet Pepsi. While it is a natural ingredient in many fruits and vegetables, most of the citric acid found in processed foods is chemically manufactured. It is added to soft drinks to give them their distinctive sharp taste, but it can also have an impact on our health.
Citric acid has been found to have a number of health benefits. It is a natural antioxidant and may offer protective benefits against disorders affecting the metabolism, nervous system, and heart. It can also help prevent gout and can reduce the risk of developing cataracts.
However, there is also some evidence to suggest that citric acid may affect blood sugar levels. A study on diabetes-induced rats found that citric acid presented a downward trend in blood sugar levels compared to a control group. This indicates that citric acid may have hypoglycemic effects. Another study found that citric acid reduced total ketone body concentration by ~70% at 24 hours after insulin injection, restoring levels to normal.
While these studies suggest that citric acid may have a positive impact on blood sugar levels, more research is needed to fully understand the effects. Soft drinks that contain citric acid are also often high in sugar, which can negatively impact blood sugar levels and overall health. Therefore, while citric acid itself may have some benefits, it is important to consider the overall sugar content of soft drinks and the potential impact on blood sugar levels.

Citric acid is used in disinfectants and cleaning products
Citric acid is a common ingredient in a wide variety of consumer products, including cleaning products, food, etc. It is naturally found in citrus fruits, such as lemons, and is also available in dry crystal form. Citric acid is a versatile and effective cleaner with antibacterial and antifungal properties, making it suitable for various applications, including disinfecting, general cleaning, and removing mineral and metal deposits.
Citric acid is particularly useful for light descaling, removing hard water stains, and tackling mineral deposits. It is often used in bathrooms, toilets, kitchens, coffee machines, and kettles. A solution of citric acid and water can be sprayed on bathroom tiles, fibreglass shower stalls, or shower doors to effectively cut through soap scum. It can also be used as a glass and window cleaner, leaving surfaces sanitized and free of smudges and stains.
Citric acid is a natural alternative to bleach, providing whitening and disinfecting properties without the harsh chemicals. It is important to note that citric acid should not be used as a disinfectant against certain diseases, such as COVID-19. When combined with bicarbonate of soda and water, citric acid creates a fizzing action that enhances its cleaning power. This natural cleaner is safer to use than more aggressive chemicals, making it a preferred choice for those seeking eco-friendly options.
Citric acid is also a key ingredient in disinfectants, leveraging its antibacterial qualities to kill bacteria and prevent the spread of germs. Its ability to bind to metal atoms and minerals through chelation makes it effective in various cleaning applications. Citric acid is safe to use, with the U.S. Environmental Protection Agency (EPA) listing it as "generally recognized as safe." However, it should be stored and handled properly, and it is always advisable to test it on a small area of the surface before full application.
Citric acid is used in Diet Pepsi as a flavouring agent and preservative. It is responsible for the distinct taste of Pepsi and contributes to its high acidity. The use of citric acid in soft drinks has raised concerns due to its potential impact on oral health, as it can dissolve tooth enamel and cause irreparable damage. However, soft drink manufacturers, including Pepsi, continue to use citric acid for its flavour-enhancing properties and its ability to extend the shelf life of their products.
