How Do Blue Foods Get Their Color?

The natural color of many fruits and vegetables is influenced by the presence of anthocyanins. These are water-soluble vacuolar pigments that are usually red, purple, or blue. They are found in all parts of the plant, including the leaves, fruits, flowers, and stems.

Anthocyanins are a superfood because they offer antioxidant and anti-inflammatory properties.

Why Are There So Few Blue Foods?

Blue foods are not as common as other colors because the pigment that creates the blue color, anthocyanin, is not as stable as other colors.

This means that it can be more easily affected by light and heat, which can degrade the flavor and nutritional value of a food.
