2457 | [Uses]
Cochineal is a red colorant extracted from the dried bodies of the female insect coccus cacti. The coloring is carminic acid in which the water-soluble extract is . It precipitates at ph 3, has good stability at ph 4, and excellent stability at ph 5–8. It has low tinctorial strength and has excellent stability to heat and light. It is also stable in retorted protein systems where other food dyes are unstable. It is used in foods requiring red coloring. | [EPA Substance Registry System]
Cochineal (dye) (1343-78-8) |
| Hazard Information | Back Directory | [Chemical Properties]
Cochineal is a red coloring material from the dried bodies of the female insect Coccus cacti and harvested from cultivated
cacti. The raw material is obtained primarily from the Canary Islands and parts of South America. Boiling cochineal with mineral
acid produces carmine red (ClH12O7). Precipitating a mixture of cochineal and alum produces a bright red pigment. Cochineal is
used as a color additive in food, drugs and cosmetics. It is also used as a microscopic stain and biological marker. | [Essential oil composition]
The principal pigment in cochineal is a protein-bound glycoside of the anthraquinone, carminic acid. |
