What is Allura Red?

Allura Red is a type of food coloring that can be found in a bright, deep red, monochromatic variety. The pigment has exceptional security as well as is commonly used in the coloring of food, drinks, medicines, cosmetics, feed, tobacco, playthings, food packaging products, etc. Water-soluble synthetic pigment, bright crimson, used in the coloring of candy layer, gelato, ice cream, candy, cakes, beverages, and so on.

Allura Red is a dark red homogeneous powder that is odorless. Soluble in water, soluble in glycerol and propylene glycol, somewhat soluble in ethanol, insoluble in oil. Liquified in water, it was a slightly yellowish red option. It has solid light resistance and warmth resistance, and also bad alkali resistance and also redox resistance. Feature resemble various other diazo red pigments. Good tolerance to liquid services containing sulfur dioxide or hydrogen ions (pH ≥ 3). Strong color fastness. Dissolved in water, neutral as well as acidic liquid options are red, and also alkaline is dark red.

  3. Allura red is used as a colorant in food, medicine and cosmetics.

Allura Red Content Detection

(1) Preparation of polysulfosalicylic acid-ruthenium terpyridine modified glassy carbon electrode
The glassy carbon electrode was placed in an aqueous solution containing 1.0×10-2mol/L sulfosalicylic acid and 1.0×10-4mol/L ruthenium terpyridine, and electropolymerized by cyclic voltammetry at -1.5~+2.0V Within the potential range of , the scanning speed was 0.1 V/s, scanning for 10 to 30 circles, and the modified electrode was obtained after taking it out to dry.

(2) Drawing of standard curve
The modified electrode prepared in step (1) was used as the working electrode, the saturated calomel electrode was used as the reference electrode, and the platinum electrode was used as the auxiliary electrode to form a three-electrode system, and 0.1mol/L PBS buffer with pH=10 was used as the blank solution for detection Luminescence intensity, the three-electrode system was placed in different concentrations of allura red (1.0×10-7mol/L, 5.0×10-7mol/L, 1.0×10-6mol/L, 5.0×10-6mol/L, 1.0× 10-5mol/L, 5.0×10-5mol/L and 1.0×104mol/L) pH=10 PBS buffer solution, cyclic voltammetry scanning in the potential range of 0.1V to 1.5V, photomultiplier tube voltage At 800V, under this condition, record the E-ECL curve, and read out the peak luminescence intensity. After statistics, the concentration of allura red is taken as the abscissa, and the luminous intensity difference between the blank solution and allura red is the ordinate, and a standard curve is drawn to obtain the corresponding linear regression equation. The linear range of the above equation is 1.0×10-7~1.0×10-4mol/L, the diameter of the glassy carbon electrode used according to the present invention is 3mm, and the detection limit is 0.6×10-7mol/L.

(3) Detection of samples
Select 1.0 mL of a commercially available watermelon beverage sample and place it in a 100 mL volumetric flask, dilute to 100 mL with 0.1 mol/L PBS buffer solution with pH=10, and take 20 mL of the obtained solution for electrochemiluminescence detection. ) the same electrochemical test method is used to test the sample solution to be tested to obtain the ECL luminescence intensity value and the difference between the luminescence intensity value of the blank solution and the luminescence intensity value of the blank solution. The equation calculates the concentration of allura red in the sample to be tested.

Preparation of Standard Materials for Allura Red

Weigh 2.15 g of a food additive-grade allura red sample (from Shanghai Institute of Dyestuffs), add 40 ml of deionized water, and prepare an aqueous solution of allura red of about 0.05 g/ml. Weigh 100g of Sephadex LH‑20 gel, add 300ml of chromatographic-grade methanol to swell for 15 minutes, and load the column (about 2 meters long) after the gel is fully swollen, and wash the gel alternately with deionized water and chromatographic-grade methanol, repeating 3 times .

The prepared allura red aqueous solution was loaded, and deionized water was used as the mobile phase for gel filtration chromatographic separation. The temperature of the chromatographic column was controlled to 20 °C, and the flow rate of the mobile phase was adjusted to 3 ml/min. 50ml, sealed and protected from light.

All fractions were detected by HPLC, and the detection conditions were: chromatographic column: GRACE Apollo C18 (250mm×4.6mm 5μm); mobile phase: methanol/0.08M aqueous ammonium acetate solution (30/70); flow rate: 1.0ml/min; Detection wavelength: 254nm and 540nm; column temperature: 40°C; injection volume: 5μl. The inventor unexpectedly found that the sixth fraction contained allura red with a purity of more than 99%, and was freeze-dried by a vacuum freeze dryer to obtain a dry allura red standard substance with a purity of more than 99%.

For other fractions containing lower purity allura red, it can be further purified by performing the above gel filtration chromatography again to obtain more allura red with a purity of more than 99%.

Allura Red Environmental Home

The production and also use Allura Red air conditioner dyes as shade additives in food, pharmaceuticals and also cosmetics can result in their release into the setting with different waste streams. If launched into the air, Allura Red air conditioner dye will just exist in the particulate phase in the ambience because it is a salt as well as non-volatile. The particulate stage Allura Red air conditioning color will certainly be removed from the environment by wet or dry deposition. The Allura Red air conditioning color contains a chromophore that soaks up > 290 nm as well as hence may be prone to route photolysis by sunshine; in experiments utilizing a 15-watt light as the UV source, its concentration stopped by 7% after 50 minutes. Allura Red AC dye is expected to relocate if released right into soil; carbon and clay than their neutral counterparts. Volatilization from moist soil surface areas is not expected to be an essential destiny process because the substance exists in an anionic form, which does not volatilize. If launched right into water, Allura Red AC color is not anticipated to adsorb to suspended solids and also sediments based upon the ionic nature of the compound in the environment. The focus of azo dyes with phenolic hydroxyl teams and two sulfonic acid groups stayed consistent throughout the activated sludge treatment process, as well as therefore are not expected to biodegrade in water and soil. Volatilization from water is not anticipated to be a crucial destiny procedure from the surface area based upon the ionic personality of the substance. Based upon the ionic buildings of the compounds, the bioconcentration potential in water organisms is anticipated to be reduced. Hydrolysis is not anticipated to be a vital environmental fate process because this compound does not have useful groups to hydrolyze under ambient conditions. In work environments where Allura Red air conditioner color is created or used, skin contact with this compound might cause job-related exposure to Allura Red air conditioner dye. Usage information show that the basic population might be subjected to Allura Red a/c dye via consumption of foods, beverages and pharmaceuticals including this color additive and skin contact with cosmetic items that use this compound.
