Chlorophyllin Copper Complexes
In plain words
The short version
A copper-stabilized form of chlorophyll — keeps a vivid green that survives heat, acid, and light.
Why it's green
It's widely considered safe at the amounts used in food, so we mark it green. The Safety section below has the details.
Safety profile
ADI of 15 mg/kg body weight. Considered safe. Free copper release is negligible under food conditions, but the copper presence is the reason for the stricter ADI versus E140.
