Abstract: Objective: To establish an HPLC method for simultaneous determination of five artificial pigments (lemon yellow, amaranth, carmine, sunset yellow and fancy red) in cooked meat products. Methods: Cooked meat products were defatted by petroleum ether, and extracted by ethanol/ammonia/water solution (7:2:1, V/V) with the assistance of ultrasound. The resultant extract was treated using a polyamide SPE cartridge. The pigments were separated on an Eclipse XDB-C18 column (5μm, 4.6 mm × 250 mm) by gradient elution with a mobile phases made up of 0.02 mol/L NH4Ac and methanol, and detected by a DAD detector at alterable wavelength. Results: The established method displayed good linearity with correlation coefficient between 0.9992 and 0.9999. The recoveries of the five pigments ranged between 89.6% and 96.4% with a relative standard deviation (RSD) between 1.24% and 4.11%.Conclusions: This method is sensitive, simple, rapid and accurate, and can be used for simultaneous determination of the five artificial pigments in cooked meat products.
