E141 — Copper chlorophyllin
E141 (Copper chlorophyllin), a color, is rated "safe": no significant concern. Chlorophyll with copper added to make the green more stable in processed foods. The copper stays bound in the molecule rather than absorbed as free copper.
What is Copper chlorophyllin?
Chlorophyll with copper substituted into the molecule so the green color survives heat and acid. Used in soups, sauces, dairy desserts, and chewing gum.
What does it do to the body?
The copper is held tightly inside the molecule, so it does not raise your copper intake meaningfully. No safety issues identified at normal use levels.
What regulators say
EFSA set an acceptable daily intake of 15 mg per kg of body weight per day in 2015 after a full re-evaluation. The FDA approves it as a safe color additive.
Risk rating: Safe
Cleared by EFSA with no significant concern at typical dietary exposure. Common, well-studied, and not a reason to put a product back on the shelf.
