3 min read

According to the official product listings from PepsiCo, acesulfame potassium has been included in Diet Pepsi's formula for many years, often alongside aspartame. This article provides a clear answer to whether does diet Pepsi have acesulfame potassium and explores why this particular sweetener combination is used.

Quick Summary

Diet Pepsi includes acesulfame potassium (also known as Acesulfame K) in its formulation, combined with other artificial sweeteners like aspartame, to achieve its specific taste profile.

Key Points

  • Yes, Diet Pepsi contains acesulfame potassium: The current formulation of Diet Pepsi in the US includes acesulfame potassium (Ace-K) as one of its primary artificial sweeteners.

  • Blended for better taste: Acesulfame potassium is typically combined with aspartame in Diet Pepsi to create a more balanced and sugar-like sweetness, as Acesulfame K can have a bitter aftertaste on its own.

  • Sweetener blend changes over time: Diet Pepsi's formula has been adjusted multiple times over its history, including a temporary shift to a sucralose and acesulfame potassium blend in the U.S. during 2015.

  • Adds heat stability: Acesulfame potassium is heat-stable, which helps prevent the sweetener blend from degrading and extends the product's shelf life.

  • Ingredients vary by region: The specific ingredients and sweetener types can differ depending on the country, so consumers should always check the label for their specific market.

  • Distinct from Pepsi Zero Sugar: While both are zero-calorie colas, Pepsi Zero Sugar uses a different sweetener blend (Ace-K and sucralose) compared to Diet Pepsi (Ace-K and aspartame), resulting in a different flavor.

Yes, Diet Pepsi Does Contain Acesulfame Potassium

For those wondering, “Does diet Pepsi have acesulfame potassium?”, the answer is yes, it does. The official ingredient list for Diet Pepsi confirms the presence of acesulfame potassium, which is often listed simply as Acesulfame K. This artificial, zero-calorie sweetener is used in conjunction with other sweeteners, most notably aspartame, to create the drink's characteristic sweet flavor without the added sugar. The use of two or more artificial sweeteners in a blend is common practice in the food and beverage industry to create a more balanced and sugar-like taste, as some sweeteners can have a bitter aftertaste on their own.

The Evolving Sweetener Recipe of Diet Pepsi

The inclusion of acesulfame potassium in Diet Pepsi is part of a larger, evolving history of its sweetener formula. Over the decades, PepsiCo has made several adjustments in response to consumer preferences and concerns:

  • Pre-1980s: The initial sweetener for Diet Pepsi was saccharin.
  • 1983: Aspartame was introduced as the primary sweetener.
  • 2012: PepsiCo began adding acesulfame potassium to the aspartame blend.
  • 2015: For a time in the U.S., aspartame was replaced with a blend of sucralose and acesulfame potassium.
  • 2018: PepsiCo reverted to the previous formula combining aspartame and acesulfame potassium in the U.S..

How Acesulfame Potassium Affects Diet Pepsi's Flavor

Acesulfame potassium, or Ace-K, is significantly sweeter than table sugar and is often blended with other sweeteners like aspartame to create a more balanced flavor profile and avoid potential bitter aftertastes. This combination aims to produce a more rounded, sugar-like taste.
