What is Allura Red Color?

Allura Red is a crimson attire powder, odorless. Soluble in water, it is a somewhat yellow-colored red solution. Light resistance, heat resistance is solid, alkali resistance and redox resistance are poor. Quality resemble other diazo red pigments. Great tolerance to aqueous remedies including sulfur dioxide or hydrogen ions (pH ≥ 3). Solid color fastness. Soluble in water, neutral and also acidic liquid remedy is red, alkaline is dark red.

Allura Red Color Uses

  1. Allura Red Shade can be used as a food tinting agent, which can be used in sweet coating according to the regulations of our nation, the optimum usage quantity is 0,085 g/kg; the maximum usage amount in deep-fried chicken spices is 0,04 g/kg; the maximum use quantity in ice cream is 0,07 g/ kg.
  2. Allura Red Color is used as a tinting representative in food, medicine and also cosmetics.
  3. Allura Red Color is used as color designer for cotton and also viscose material dyeing as well as printing, as well as also as dye intermediate.

Preparation of Standard Materials for Allura Red Color

Evaluate 2.15 g of a food additive-grade Allura Red Color sample (from Shanghai Dyestuff Research Study Institute), include 40ml of deionized water, and also prepare a 0.05 g/ml Allura Red liquid remedy. Evaluate 100g of Sephadex LH‑20 gel, include 300ml of chromatographic grade methanol to swell for 15min, pack the gel right into a column (regarding 2 meters long) after the gel is fully swollen, and wash the gel at the same time with deionized water and chromatographic grade methanol, repeat 3 times.

Lots the ready Allura Red Color liquid remedy, utilize deionized water as the mobile phase for gel filtering chromatography, regulate the temperature of the chromatographic column at 20 ° C, readjust the flow rate of the mobile phase to 3ml/min, split each flow 50ml solution, all fractions were sealed and saved far from light.

Perform HPLC detection on all portions, where the detection problems are: chromatographic column: poise Beauty C18 (250mm × 4.6 mm 5μm); mobile stage: methanol/0.08 M ammonium acetate liquid option (30/70); circulation price: 1.0 ml/min; Discovery wavelength: 254nm and 540nm; column temperature level: 40 ° C; injection quantity: 5μl. The creator unexpectedly found that the 6th portion had Allura Red with a pureness of more than 99%, and also was freeze-dried by a vacuum cleaner freeze clothes dryer to get a completely dry Allura Red Shade conventional material with a purity of more than 99%.

For other fractions containing Allura Red with lower purity, it can be more cleansed by carrying out the above gel filtration chromatography once more, so regarding obtain even more Allura Red Shade with a purity of more than 99%.

Content Detection of Allura Red Color

(1) Prep work of polysulfosalicylic acid-terpyridine ruthenium-modified glassy carbon electrode
Location the glassy carbon electrode in a liquid option including 1.0 × 10-2mol/ L sulfosalicylic acid and 1.0 × 10-4mol/ L ruthenium terpyridine, as well as perform electropolymerization by cyclic voltammetry. Within the possible variety, the scan rate is 0.1 V/s, check 10 to 30 circles, obtain and dry to obtain the changed electrode.

( 2) Drawing of standard curve
The modified electrode prepared in step (1) was utilized as the working electrode, the saturated calomel electrode was made use of as the reference electrode, as well as the platinum electrode was made use of as the complementary electrode to develop a three-electrode system, and also the 0.1 mol/L PBS barrier solution with pH= 10 was utilized as the blank remedy for discovery Luminescent strength, the three-electrode system was put 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 as well as 1.0 × 104mol/L) PBS buffer remedy of pH= 10, carry out cyclic voltammetry scanning in the possible variety of 0.1 V to 1.5 V, the voltage of photomultiplier tube It is 800V. Under this problem, document the E-ECL contour and also read out the height worth of the luminous strength. After statistics of the acquired information, take the focus of Allura Red Color as the abscissa, and the luminescent intensity difference in between the blank remedy as well as Allura Red as the ordinate, draw a typical curve, and then get the matching direct regression formula. The linear range of the above equation is 1.0 × 10-7 ~ 1.0 × 10-4mol/ L, the size of the glazed carbon electrode made use of according to the here and now innovation is 3mm, as well as the discovery limit is 0.6 × 10-7mol/ L.

( 3) Detection of examples
Select commercially readily available watermelon beverage sample 1.0 mL as well as location it in a 100mL volumetric flask, set the volume to 100mL with a 0.1 mol/L PBS barrier service of pH=10, get 20mL of the gained solution for electrochemiluminescence detection, and also comply with steps (2) the same electrochemical examination technique to evaluate the sample service to be checked to acquire the ECL luminescent strength value and also its difference with the empty remedy luminous strength worth, and also the resulting luminescent intensity value difference is direct regression corresponding to the conventional contour obtained in step (2) The equation computes the focus of Allura Red Shade in the sample to be evaluated.
