Carminic acid, typically 17–24% of dried insects' weight, can be extracted from the body and eggs, then mixed with aluminium or calcium salts to make carmine dye, also known as cochineal. Today, carmine is primarily used as a colorant in food and in lipstick (E120 or Natural Red 4).

Besides carminic acid, it contains soluble proteins, carbohydrates, other residual material from the insect, and various ionic salts from the extraction process. In addition to liquid formulations, cochineal is also available as spray-dried powder with a …

2012年6月15日 · Conventional industrial cochineal processing is a multiple step procedure consisting of treatment with organic solvents, alkaline extraction, solid–liquid separation (flocculation and filtration), insoluble lake formation, recovery of the precipitate (centrifugation), resolubilisation of carminic acid and concentration.

Cochineal, Dactylopius coccus, is a small scale insect native to subtropical South America through the Southwest United States that lives in stationary clumps on nopal, prickly pear cacti of the genus Opuntia.

Product appearance: Purple liquid; Aqueous solution of carmine, stabilized in alkali solution and when required also in emulsifier; Completely miscible in water; Carminic acid content: 2 – 20%; Color shade provided: Red Yellowish to Red Bluish; Main applications: Meat, yogurt, milk drinks, ice creams, confectionery and pastry

2024年11月25日 · Carminic acid is a natural pigment typically found in several insect taxa, including specific insects such as “grana cochinilla fina” in Mexico (Dactylopius coccus Costa). Commercially, it is also referred to as carmine, which is a more concentrated solution presenting as at least 50% carminic acid.

2020年7月1日 · This review chapter deals with the chemistry, extraction, application, and colorimetric analysis of colorants derived from turmeric (root), annatto (seeds), and cochineal (insect) for use on both...

This dye is a common additive to food, drugs and cosmetics. Cochineal has excellent light and washfastness and produces a powerful range of fuchsias, reds and purples. Although expensive, cochineal has a high concentration of carminic acid and only small amounts are needed. See the MAIWA GUIDE TO NATURAL DYES

Cochineal is the primary extract which is a purple-red liquid. It is available in liquid, crystal, or powdered form. It can be orange-yellow at a pH from 4 to 6.5, and purple-red above pH 6.5. Carmine is made by precipitating Carminic Acid onto an alumina hydrate substrate, using aluminum or calcium cations. Carmine is insoluble in water and oil.

Our cochineal insect instructions will help extract color from cochineal insects, native of Mexico and South America. These scale insects produce carminic acid and are a traditional way of obtaining bright red, brilliant pink, and purple dyes.
