摘要:
A species-specific SCAR marker for rainbow trout, which was used to detect adulteration and fraudulent labeling in Atlantic salmon products, has been developed based on the AFLP analysis and evaluated in this study. The SCAR marker could be amplified and visualized in 1% agarose gel in all tested rainbow trout samples and absent in all salmon samples. Using DNA admixtures, the detection of 1% (0.5 ng), 10% (5 ng) rainbow trout DNA in Atlantic salmon DNA for fresh and processed samples, respectively was readily achieved. The molecular approach was sensitive and demonstrated to be a rapid and reliable method for identifying frauds in salmon products and could be extended for applications of species identification in food industry.
