Objective To establish a method of rapid identification of the authenticity of Gadus macrocephalussource components by TaqMan fluorescent PCR. Methods Targets were detected by Gadus macrocephalus mitochondrial cytochrome oxidase CoxI, specific primers and probes were designed, specificity and sensitivity tests were performed, and commercially available samples were tested. Result The primers of this method had good specificity and sensitivity, and could well distinguish between Gadus macrocephalus and other species of fish, with a sensitivity of 0.04 ng/μL.Among the commercially available samples, Gadus macrocephalus were found in 90.9% of Gadus macrocephalus slices and 71.4% of Gadus macrocephalus canned food. Conclusion The method has good specificity and sensitivity, which is suitable for the authenticity screening of Gadus macrocephalus componentsin most products.
