Carmine Pigment

Product Introduction

Carmine is a pigment obtained from inside the body of female cochineal insects. These insects grow on cactus plantations in Central and South America. A large part of cochineal red now comes from Peru because of the favorable climate in Peru and the rich resources of wild and artificial cactus plantations. As a safe natural pigment, carmine cochineal extract is economically and socially important to study the extraction of cochineal red pigment.

Carmine is red to deep red uniform granules or powder, odorless. Good light resistance and acid resistance, strong heat resistance (105°C), poor reduction resistance; poor bacteria resistance. It is easily soluble in water and glycerin, hardly soluble in ethanol, and insoluble in oil.

As a food coloring, carmine can be used in the coloring of juice drinks, mixed wine, carbonated drinks, candies, cakes, ice cream, yogurt and other foods, but not in dried meat, dried meat products, aquatic products and other foods, mainly to prevent some Criminals deceive consumers by using pigments to cover up the appearance of bad raw meat such as spoiled meat.

Application

Carmine as a food pigment can be used for juice beverage, make wine and carbonated drinks, candy, cakes, ice cream, yogurt and other food coloring, and cannot be used for dried meat, meat products, aquatic products such as food, mainly in order to prevent some lawless elements through the use of pigment will bad raw meat such as cover up the appearance of the metamorphic meat, cheat consumer

Applied in food field, it is mainly used as natural food additives for colorant;
2. Applied in cosmetic field and pharmaceuticals, it is mainly used as red colorant;
3. As senior dye, widely used in textile manufacturing industry, such as toys, senior textile, wool products etc.

Test method

1. High performance liquid chromatography
The principle of using high-performance liquid chromatography to detect carmine is to extract it with polyamide adsorption method or liquid-liquid distribution method, make an aqueous solution, inject it into a high-performance liquid chromatograph, and separate it by reversed-phase chromatography. Area comparisons were performed for the quantification of carmine.
2. TLC
The principle of using thin-layer chromatography to detect carmine is that the water-soluble acidic synthetic colorant is adsorbed by polyamide under acidic conditions, and desorbed under alkaline conditions, and then separated by paper chromatography or thin-layer chromatography. Qualitative and quantitative comparison with standards.
3. Oscillometric Polarography
The principle of using oscillographic polarography to detect carmine is that the synthetic colorant in food can produce sensitive polarographic waves on the mercury dropping electrode in a specific buffer solution, and the wave is proportional to the concentration of the colorant. This method can be used for qualitative and quantitative analysis when there are one or more colorants that do not affect the determination of each other in food.
4 microcolumn method
The principle of micro-column detection of synthetic pigments is that, according to the characteristics that water-soluble acidic synthetic pigments are adsorbed by polyamide under acidic conditions and desorbed under alkaline conditions, the distribution coefficient of the separated substances between the adsorbent and the developing agent is different. , to achieve the purpose of separation.
