E140 / Colours
Chlorophylls, chlorophyllins
Safety in brief
Safe
Recorded EatMatrix rating, not a new clinical review. The amount, your sensitivities and country rules still matter.
- Watch for
- No allergen or sensitivity is recorded for this ingredient here. Check the whole product label; this is not an allergen-free guarantee.
- Our advice
- Read the whole food label and consider how often you eat the product. A name or E number does not tell you the amount, and an ingredient rating cannot assess the entire food.
What it is
Chlorophylls and chlorophyllins are natural green pigments derived from plants, where they play a key role in photosynthesis. Chlorophyllins are water-soluble derivatives made by modifying the chlorophyll molecule (often replacing its magnesium with copper) to improve stability for use in foods and beverages. Both are used as natural green colourants in confectionery and processed foods and are considered safe by EFSA and the FDA within regulatory limits.
