Further, a highly appreciated natural dye based on carminic
acid is obtained from cultivated Dactylopius coccus Costa (Hemiptera: Dactylopiidae) reared on the cladode.
The red color comes from carminic
acid, which the insects have in abundance.
Dactylopius coccus, is commonly sun-dried, crushed and dipped in an alcohol solution to create carminic
acid--the pigment which eventually becomes the colorant carmine or cochineal extract for use in food and beverages.
1999) reported that natural colorants such as carminic
acid, caramel, beta-carotene, paprika-extract and betanin decreased the L* values of frankfurters.
Chemical analysis on one of the metal pieces indicate the presence of carminic
and alginic acids, often used in cosmetics," King said.

The composition comprises at least one natural dye chosen from orceins, alizarin, purpurin, carminic
acid, kermesic acid, purpuroqallin, protocatechaldehyde, indigo, curcumin, spinulosin, apiqenidin, chlorophyllin, sorghum, and cochineal carmine and at least one organic solvent.
Carmine (carmine, cochineal, or carminic
acid) is a red colouring made from a ground-up insect, used in bottled juices, coloured pasta, some sweets, frozen pops, and "natural" cosmetics.
The bugs when feeding on nopal sap produce a white wax-like coating, but become dark bluish red when engorged with eggs on a three-month cycle, and ooze up to 25 percent pure scarlet-colored carminic
acid--also known as hydroxyanthraquinone
acid, the active colouring agent, is one of the safest dyes that exist and is commonly used in foods and cosmetics.
