Copper Complexes of Chlorophylls (E141) — What You Need to Know
What Is Copper Complexes of Chlorophylls?
Copper Complexes of Chlorophylls are produced by replacing the magnesium atom in natural chlorophyll with copper, creating a much more stable green pigment. This modification makes the color resistant to heat, light, and acid, unlike natural chlorophylls (E140).
What Is It Used For?
Provides a stable bright green color in foods where natural chlorophyll would degrade. Widely used in EU confectionery, canned vegetables, and beverages.
Safety Assessment
The copper complexation makes chlorophyll more stable to heat, light, and acid compared to natural E140. EFSA set ADI at 15 mg/kg bw/day based on copper content — excess copper intake can cause gastrointestinal effects. Not approved in the US. The 2015 EFSA re-evaluation noted that exposure was well below the ADI for all population groups.
Based on current evidence, Copper Complexes of Chlorophylls is rated Generally Safe with a score of 7/10. This is 1.2 points above the average for colorings (5.8/10). Last reviewed by regulators: 2015.
