Artificial Colors Red 40 Lake

Red 40 Lake is a synthetic color additive that provides a red hue. It is the 'lake' form of Red 40 dye, meaning it is made by combining the dye with a metallic salt, usually aluminum. This process makes the color insoluble in water, allowing it to be dispersed in products rather than dissolved.

Manufacturers add Red 40 Lake to foods to provide a stable red color, especially in products with low moisture or high fat content. It is commonly found in candies, baked goods, snack coatings, and other processed foods. Its insoluble nature helps prevent color bleeding.

Red 40 Lake is an FDA-approved color additive for use in food. In April 2025, FDA announced a plan to phase out petroleum-based synthetic dyes, including Red 40. Some studies have suggested a possible link between synthetic food dyes, including Red 40, and hyperactivity in some children; however, evidence is mixed, and regulatory bodies like the FDA state that current evidence does not establish a causal link for the general population. JECFA has evaluated it and set an acceptable daily intake. EFSA has also evaluated this additive.
