To Protect Flavor Red 40

Red 40, also known as Allura Red AC, is a synthetic food coloring. It is manufactured from petroleum and is one of the most commonly used artificial red dyes in the United States. It provides a bright red color to a wide variety of food and beverage products.

Manufacturers add Red 40 to foods and drinks to achieve a red hue and enhance visual appeal. It is frequently found in items like sodas, energy drinks, candies, cereals, and baked goods. Its stability and vibrant color make it a popular choice for many processed food products.

Red 40 is an FDA-approved color additive for use in food and cosmetics. JECFA has evaluated Red 40 and set an acceptable daily intake. EFSA has also evaluated its safety. There has been public concern and some studies suggesting a link between synthetic food dyes, including Red 40, and hyperactivity in some children; however, the FDA states that the available scientific evidence does not support a causal link between exposure to these color additives and behavioral effects in the general population of children. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Red 40.
