Carmine Food Colors Powder Food Red No. 102
Product Description
Carmine is red to dark red uniform granules or powder, odorless. It has good light resistance and acid resistance, strong heat resistance (105ºC), poor reduction resistance; poor bacterial resistance. It is soluble in water, and the aqueous solution is red; it is soluble in glycerin, slightly soluble in alcohol, and insoluble in oils and fats; the maximum absorption wavelength is 508nm±2nm. It is stable to citric acid and tartaric acid; it turns brown when exposed to alkali. The coloring properties are similar to amaranth.
Carmine appears to be a red to dark red powder. It is easily soluble in water and glycerin, difficult to dissolve in ethanol, and insoluble in oils.

Function
1. Cochineal Carmine is an excellent natural food red pigment. It shows bright purplish red in weak acid or neutral environment, but its color changes under alkaline conditions. The maximum absorption of pigment solution at the pH value of 5.7 occurred at 494 nm.
2. The pigment had good storage stability and thermal stability, but poor light stability. After 24 hours of direct sunlight, the pigment retention rate was only 18.4%. In addition, the pigment has weak oxidation resistance and is greatly affected by metal ion Fe3 +. But the reducing substance can protect the color of pigment.
3. Cochineal Carmine is stable to most food additives and has a wide range of application.
Applications
1.Cosmetic: Can be used for lipstick, foundation, eye shadow, eyeliner, nail polish.
2.Medicine: Carmine in the pharmaceutical industry, as a coating material for tablets and pellets, and colorants for capsule shells.
3.Food: Carmine can also be used in food such as candy, drinks, meat products, coloring.
