Pistachios are green because of chlorophyll, the same pigment that gives other fruits and vegetables their green color.
Here's a more detailed explanation:
-
Chlorophyll is Key: Chlorophyll is the green pigment essential for photosynthesis in plants. Photosynthesis is the process where plants convert light energy into chemical energy.
-
In the Pistachio Seed: The edible part of the pistachio, the seed, retains chlorophyll as it develops. This is why you see the characteristic green color, often with hints of purple depending on the variety and maturity.
-
Not the Shell: It's important to distinguish between the seed and the shell. The shell of a pistachio is typically a beige or tan color. The green color is specific to the seed itself.
In short, the green color in pistachios is a natural outcome of the chlorophyll present in the seed during its growth and development.
