What You'll Learn
Carbonated water, caramel colour, phosphoric acid, and citric acid
Carbonated water is the primary ingredient in Diet Pepsi, providing the fizziness that has come to define cola drinks. The carbonation process involves dissolving carbon dioxide in water under high pressure, which, when released, forms bubbles and creates that distinctive mouthfeel. This process also helps to enhance the flavour of the drink.
Caramel colour (or colour caramel) is added to give Diet Pepsi its characteristic brown hue. This colouring is created by carefully heating carbohydrates, such as glucose, in a process known as caramelization, which produces the desired shade. The use of caramel colouring is common in colas and other products, including baked goods and spirits, where a specific colour is desired.
Phosphoric acid is another key component of Diet Pepsi's flavour profile. It is a colourless, odourless phosphorus-containing acid that provides a tangy, sour taste. In addition to its flavour contributions, phosphoric acid also acts as a preservative, helping to extend the shelf life of the beverage by inhibiting microbial growth.
Citric acid, the final ingredient in this list, is a natural preservative and flavouring agent found in many citrus fruits, including lemons and limes. It enhances the tartness of Diet Pepsi, contributing to the overall flavour profile. Citric acid also has antimicrobial properties, further supporting the preservation of the drink.

Sweeteners: aspartame, acesulfame potassium, and sucralose
Diet Pepsi contains the artificial sweeteners aspartame, acesulfame potassium, and sucralose. These low-calorie sweeteners are designed to impart a sweet taste without the calories or glucose effects of sugar. However, there is insufficient evidence that they aid with weight loss or improve overall health. In fact, some studies suggest that low-calorie sweeteners may condition people to crave sweet foods and, as a result, consume fewer servings of healthy foods.
Aspartame, also known by the brand name NutraSweet, was introduced to Diet Pepsi in 1983, replacing the previously used artificial sweetener saccharin. Aspartame has been deemed safe for human consumption by regulatory agencies in their respective countries, including the U.S. However, it has been the subject of controversy, with critics expressing concerns about potential health risks associated with its consumption. These concerns include allegations that aspartame may be linked to the development of brain tumors in humans.
Acesulfame potassium, also known as acesulfame K, is another artificial sweetener found in Diet Pepsi. It is often used in combination with other sweeteners, such as aspartame, to enhance sweetness and improve taste. Acesulfame potassium is a calorie-free sweetener that is approved for use in various food and beverage products.
In 2012, Pepsi announced that it would be changing the sweetener in Diet Pepsi to sucralose ahead of a major rebranding in 2013. This change sparked mixed reactions, with some consumers expressing their distaste for the new formula. In response to the feedback, Pepsi reintroduced the aspartame-sweetened formulation in 2016, which was sold alongside the sucralose-sweetened version.

Preservatives: sodium benzoate and potassium benzoate
Preservatives are added to food and drinks to prevent spoilage and extend their shelf life. They are particularly important in products like soft drinks, which are often stored for long periods before consumption. Sodium benzoate and potassium benzoate are two common preservatives used in Diet Pepsi, depending on the country of origin.
Sodium benzoate, also known as E211, is a synthetic preservative that is widely used in the food and beverage industry. It is the sodium salt of benzoic acid and effectively inhibits microbial growth, preventing the spoilage of carbonated drinks like Diet Pepsi. In some countries, such as the United Kingdom, it is declared on the ingredient list as "sodium benzoate." Meanwhile, in other countries like the United States, it may be listed as "benzoic acid" or simply included in the broader term "preservatives."
Potassium benzoate, on the other hand, is another commonly used preservative in the form of a potassium salt of benzoic acid. It serves the same purpose as sodium benzoate, preventing the growth of microorganisms and preserving the freshness of the product. In the United States, for example, Diet Pepsi lists "potassium benzoate (preserves freshness)" as one of its ingredients. This transparency in ingredient labelling helps consumers understand the purpose of each component.
The use of preservatives like sodium benzoate and potassium benzoate is essential in maintaining the quality and safety of food and beverage products. They play a critical role in inhibiting microbial growth, ensuring that products remain safe for consumption over extended periods. However, it is worth noting that some people may have sensitivities or allergies to certain preservatives, so it is always important to read the ingredient labels and be aware of the contents of the products one consumes.

Flavours: natural flavour, caffeine, and vanilla
Diet Pepsi is a sugar-free, carbonated cola soft drink produced by PepsiCo and introduced in 1964. It is the company's first diet cola to be distributed on a national scale in the United States.
The ingredients in Diet Pepsi vary slightly depending on the country of origin. In the US, the ingredients listed are: carbonated water, caramel colour, aspartame, phosphoric acid, potassium benzoate (preserves freshness), caffeine, citric acid, natural flavour, acesulfame potassium, and phenylketonurics.
Natural flavour, caffeine, and vanilla are three of the key ingredients in Diet Pepsi. Natural flavour is used to enhance the taste of the drink, and it is often a closely guarded secret by beverage companies. In the case of Diet Pepsi, the natural flavour is likely a blend of ingredients that complement the other flavours in the drink, such as the caramel colour and phosphoric acid.
Caffeine is a stimulant that is commonly found in soft drinks and is added to Diet Pepsi to provide a mild energy boost to consumers. It is a central nervous system stimulant that can enhance alertness and improve focus. Vanilla, on the other hand, is a flavouring agent that is sometimes added to Diet Pepsi as a variation. While it is not listed as an ingredient in the standard Diet Pepsi formula, Pepsi does produce Diet Pepsi Vanilla, which includes vanilla flavouring. This variation was introduced to provide consumers with different flavour options, and it has been well-received by those who enjoy a sweeter, more aromatic cola experience.
The combination of natural flavour, caffeine, and vanilla (in the case of Diet Pepsi Vanilla) contributes to the unique taste profile of Diet Pepsi and helps differentiate it from other cola products in the market. These ingredients work together to create a refreshing, crisp, and flavourful drinking experience that has contributed to the brand's success and longevity.

History of ingredients: from saccharin to aspartame
The history of Diet Pepsi's ingredients is a story of innovation and adaptation to changing consumer preferences and regulatory requirements. When it was first introduced in 1964, Diet Pepsi was a sugar-free variant of the regular Pepsi cola. Over the years, the ingredients in Diet Pepsi have evolved, particularly in response to concerns about the safety of artificial sweeteners and changing consumer tastes.
Initially, Diet Pepsi was sweetened with saccharin, an artificial sweetener. However, concerns about the safety of saccharin emerged in the 1970s, and it nearly got banned by the FDA in 1977. As a result, PepsiCo made the decision to switch to a new sweetener, aspartame, which was marketed as the brand NutraSweet. This change took place in 1983, and Pepsi began selling diet colas with 100% aspartame sweetening. This decision was driven not only by safety concerns but also by taste preferences, as many consumers found that saccharin left a metallic aftertaste.
Aspartame is a highly sweet substance, approximately 200 times sweeter than sugar. It is produced by combining two amino acids. The switch to aspartame gave new impetus to the fast-growing diet soft drink field, and Diet Pepsi sales increased by 30% after the company began using the new sweetener. However, aspartame has also been controversial. In 1996, a "60 Minutes" report raised concerns about a possible link between aspartame consumption and the development of brain tumours in humans.
Despite the controversy, regulatory agencies in several countries, including the U.S. Food and Drug Administration (FDA), the U.K. Food Standards Agency, the European Food Safety Authority (EFSA), and Health Canada, have deemed aspartame safe for human consumption at current levels. In 2012, Diet Pepsi changed its sweetener to sucralose, but this was met with negative feedback from consumers. As a result, Pepsi revived its aspartame formulation in 2016, selling it as "Diet Pepsi Classic Sweetener Blend" in the US alongside the new formula.
