Abstract:To find out the content of thiocyanate in raw milk of Hebei Province. Methods Following the principles of representativeness, randomness and timeliness, 159 raw milk samples were collected from Hebei Province in 2013, including 100 samples from dairy farmers, 32 samples from milking workshop, 27 samples from milk tankers in a dairy plant. Thiocyanate were determined by ion chromatography refering to standard determination operating procedures of sodium thiocyanate in foods in National food contamination and harmful risk handbook. Results The content of 48 samples were below the detection limit, the maximum value was 6.45 mg/kg, P50 was 1.32 mg/kg, and P95 was 2.94 mg/kg.Conclusion Thiocyanate levels of 159 raw milk samples were lower than the values reported in the literature.
