Abstract

The objective of this experiment was to find out the content of sodium thiocyanate (SCN) in raw milk in Inner Mongolia area, to provide the data reference of limited provision of SCN in raw milk. The contents of SCN in 2 443 batches raw milk which came from 10 cities/leagues in Inner Mongolia area during 2013 to 2017 were detected. The results showed as follows:1) the contents of SCN in 2 443 batches raw milk in Inner Mongolia area during 2013 to 2017 were all detected in varying degree, the detection range was 0 to 12.00 mg/kg, the average content of SCN in raw milk was 1.67 to 3.79 mg/kg, which showed a decreased trend year by year. The average content of SCN in raw milk in 2013 was significantly higher than that in 2014, 2015 and 2017 (P<0.05), and the average content of SCN in raw milk in 2014 and 2015 was significantly higher than that in 2017 (P<0.05), the average content of SCN in raw milk during 2013 to 2017 was 2.75 mg/kg. The detection rate of SCN was 32.20% to 99.09%, which showed a decreased trend year by year, and the average detection rate of SCN was 78.14%. 2) The average content of SCN in raw milk was 1.79 to 5.81 mg/kg in 10 cities/leagues in Inner Mongolia area. The average content of SCN in raw milk in Xilingol league was significantly higher than that in other cities/leagues except Ulanqab city (P<0.05). The detected maximum value of SCN content in raw milk in Hulun buir city was the highest, which was 12 mg/kg; the detection rate of SCN in Baotou city and Ordos city was the highest, which was 100.00%. In conclusion, the content and detection rate of SCN in raw milk in Inner Mongolia area show a downward trend year by year, and there is no risk in exogenous addition, the contents of SCN in raw milk are difference in different cities/leagues.
