How Cochineal Provides a Natural and Sustainable Red Colorant

Cochineal is a natural red dye derived from the dried bodies of female Dactylopius coccus insects, which live on cacti. For centuries, it has been valued for its brilliant crimson color, high stability, and wide acceptance in food, cosmetics, and pharmaceuticals. Today, cochineal remains an important natural alternative to synthetic dyes.

Composition of Cochineal

The coloring strength of cochineal comes from carminic acid, which can make up 15–25% of the insect’s body weight. After extraction, it can be processed into cochineal extract or carmine, a water-soluble aluminum and calcium salt of carminic acid.

• Carminic acid content: 15–25%

• Appearance: Dark red to purple powder or liquid extract

• Origin: Natural, insect-based
