Blue #1 And Calcium Disodium EDTA To Protect Color

Blue #1, also known as Brilliant Blue FCF, is a synthetic food dye derived from petroleum. Calcium disodium EDTA (ethylenediaminetetraacetate) is a synthetic salt produced through chemical synthesis.

Blue #1 is used to impart a bright blue color to various foods and beverages, including soft drinks, desserts, and candies. Calcium disodium EDTA functions as a chelating agent and preservative, binding to metal ions to prevent oxidation and maintain the color and freshness of foods, often used in canned goods, dressings, and beverages.

Both Blue #1 and Calcium disodium EDTA are approved food additives by the FDA. Blue #1 has been evaluated by JECFA and EFSA, and while generally considered safe, some studies have suggested a possible link between synthetic food dyes and hyperactivity in some children, though evidence is mixed. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue #1. Calcium disodium EDTA has also been evaluated by JECFA and EFSA, which have set an acceptable daily intake, and it is considered safe at typical intake levels in food.
