In this paper, HPLC was used to detect the melamine in raw milk and dairy products. In HPLC method, melamine was extracted by trichloroacetic acid and acetonitrile. The detection limit of this method is 0.5 mg/kg, the relative standard deviation was 1.09%-1.99%and the recoveries between 95.15%-99.12%. Compared with the first method in GB/T 22388-2008, this method processing time is reduced by about 3 h.
