Overview

E140I - Chlorophylls

Chlorophylls (E140i) are green pigments extracted from edible plants and used to color foods. They give a natural-looking green shade and are most at home in fatty or oily foods like sauces, fillings, and confectionery coatings. This page covers what they do, where they show up, and how they’re regulated.

E141 - Copper complexes of chlorophylls and chlorophyllins

Copper complexes of chlorophylls and chlorophyllins (E141) are green food colors made by bonding copper to plant chlorophyll. They keep foods looking bright green even when heated or stored in acidic conditions. Two forms exist: E141(i), which is fat‑soluble, and E141(ii), which is water‑soluble.

Popular questions

Does chlorophyll have magnesium?
Yes—chlorophylls (E140i) contain a central magnesium ion. If Mg is lost during processing (forming pheophytin), the green color dulls.
"what is the function of the magnesium atom in a chlorophyll molecule"?
The magnesium sits at the center of the chlorin ring, coordinating four nitrogens and tuning the electronic structure to absorb light. This enables efficient energy/electron transfer in photosynthesis and contributes to the green color.
1 gram contains 2.68 % magnesium. how many atoms of mg will there be in 1.00 g of chlorophyll?
At 2.68% Mg, 1.00 g contains 0.0268 g Mg ≈ 0.00110 mol (24.305 g/mol). That is about 6.6×10^20 magnesium atoms (0.00110 × 6.022×10^23).
2. what is the function of the magnesium atom in a chlorophyll molecule?
The Mg ion is the central coordinating atom of the pigment’s ring, shaping the absorption spectrum so chlorophyll can harvest light and transfer energy.
3. what is the function of the magnesium atom in a chlorophyll molecule?
It serves as the central metal that stabilizes the chlorin ring and enables light absorption; removing Mg alters the color and photochemistry (pheophytin formation).
