Anthocyanins vs Cochineal Extract: which is worse?

What is Anthocyanins?

Anthocyanins are a class of water-soluble pigments found in red, blue, and purple fruits and vegetables (blueberries, red cabbage, elderberries, grapes, black beans). They are flavonoid compounds responsible for the red-to-blue color spectrum in plants. As a food additive (E163), they are extracted from plant sources including grape skins, elderberries, or black carrots.

What is Cochineal Extract?

Cochineal extract is a red pigment derived from the dried bodies of female cochineal insects (Dactylopius coccus), which feed on prickly pear cacti in Central and South America. Approximately 70,000 insects are needed to produce 1 pound of dye. The active compound is carminic acid. It provides stable red, pink, and purple colors and has been used since Aztec times.

Documented risks

Anthocyanins: Anthocyanins are not only safe but are associated with numerous health benefits including antioxidant, anti-inflammatory, and cardioprotective effects, extensively documented in nutritional epidemiology literature. The color is pH-sensitive (red in acid, blue/purple in neutral/alkaline), which can be a formulation challenge but presents no health risk. No significant adverse effects have been identified at food additive use levels.

Cochineal Extract: Cochineal extract and carmine are associated with potentially severe allergic reactions, including anaphylaxis. The FDA received multiple adverse event reports, and in 2009 issued a final rule requiring cochineal extract and carmine to be declared by name on food labels (rather than being permitted under 'artificial color'). EFSA confirmed its safety in 2015 but acknowledged allergic risk. Vegans and those following halal or kosher diets should avoid it as it is insect-derived.
