Cochineal red is a natural pigment that has been long history.
As early as 4000 years ago, the indigenous peoples of Central and South America used cochineal to produce paint. After being discovered by Spanish colonialist, it quietly brought it back to Europe to monopolize the entire industry, at a price comparable to gold at the time. Although chemical synthetic dyes came out soon, cochineal was greatly impacted, but its naturalness and safety have always been sought after by people.
It can be used as a coloring agent for beverages such as wine, fruit pulp, cold drinks, candies, cakes, meat, sausages, etc., and can also be used in cosmetics.
The marker ingredient is carminic acid.
Properties and indicators: yellow at PH=4.5; orange at PH=5.0; red at PH=5.5; purple-red at PH≥6.0. The light resistance of the pigment in the range of orange, red to purple-red is better, and the light resistance is poor when the pH value is about 4.5 and 7.0-7.5. Good thermal stability. The hue becomes lighter or colorless when encountering iron ions. The compound phosphate has a protective effect on the pigment.
Source: Extracted from Dactylopius coccus. Grind the dry body of the insect, soak it in hot water at 60-70℃, and stir it from time to time. After a day or so, most of the pigment can be extracted, and after the second extraction, the extract ratio can reach as high as almost 100%. The two filtrates were combined and concentrated under reduced pressure to obtain the pigment.
