PG  - 743-6
AB  - A method for the determination of thiocyanate in dairy products by headspace gas 
      chromatography was established. At first, the thiocyanate in dairy products was 
      extracted by water. Then, the zinc acetate solution was added to the crude 
      product for protein precipitation. The extract obtained above was centrifuged and 
      the supernatant was added with chloramine T, which derivatized the thiocyanate 
      ions to cyanogen chloride. The head-space vapor of the final extract was injected 
      into a BP10 (14% cyanopropyl phenyl polysiloxane) gas chromatographic column, and 
      detected by an electron capture detector (ECD). The target compound was 
      quantified by external standard. The results showed that there was a good 
      linearity between 0.005 mg/L and 0.1 mg/L with the correlation coefficient (r) of 
      0.997, and the limit of detection (signal-to-noise ratio (S/N) > or = 10) was 0.1 
      mg/kg. The recoveries were 90.0%-110.0% with the relative standard deviations 
      (RSDs) (n = 10) of 4.98%-7.89% at the three spiked levels of 1.0, 2.0, 10.0 
      mg/kg. In conclusion, this method is simple, rapid and accurate. It can be 
      applied in the determination of thiocyanate in dairy products, and meets the 
      requirements of the daily testing. The method has been successfully used to test 
      18 kinds of commercially available dairy products and it was found that all the 
      dairy products tested contained thiocyanate about 0.5-10 mg/kg
