Blue 2 And Acesulfame Potassium

Blue 2, also known as Indigo Carmine, is a synthetic blue food dye. It is manufactured from coal tar and is approved for use in the U.S. Acesulfame potassium (Ace-K) is an artificial sweetener, about 200 times sweeter than sugar. It is produced through a chemical process.

Blue 2 provides a blue color to foods and is often used in candies, beverages, and baked goods. Acesulfame potassium is used to sweeten a variety of products, including diet sodas, sugar-free desserts, and tabletop sweeteners, often in combination with other sweeteners.

Blue 2 is an FDA-approved color additive. Acesulfame potassium is FDA-approved as a high-intensity sweetener. Both ingredients have been evaluated by JECFA and EFSA. While generally recognized as safe at typical consumption levels, some studies have raised questions about potential health effects, though regulatory bodies have not found sufficient evidence to change their safety assessments. In 2023, IARC classified aspartame, another artificial sweetener, as possibly carcinogenic to humans (Group 2B), while JECFA maintained its existing ADI.
