- Spinach extract: A concentrated form of the green pigment found in spinach leaves.
- Spirulina: A blue-green algae that contains a green pigment called phycocyanin.
Artificial Green Food Dyes
Artificial green food dyes are synthetic compounds that are designed to imitate the color of natural green pigments. Common artificial green food dyes include:
- FD&C Green No. 3: A synthetic dye that is used in a wide variety of food products, including candy, ice cream, and soft drinks.
