辐照对烤鳗制品中药物残留的影响

Effects of Irradiation on Pesticide Residues of Roast Eels

为实现科学安全的降解烤鳗药物残留,采用60Co-γ射线对烤鳗进行处理,分别设置辐照剂量为0 kGy、1 kGy、3 kGy、5 kGy、7 kGy、9 kGy,考察辐照剂量对烤鳗制品中4种氟喹诺酮类和隐色结晶紫残留量的影响。结果表明:辐照对四种氟喹诺酮类和隐色结晶紫均有降解效果,当辐照剂量5 kGy时,影响达显著水平,此时,氧氟沙星、环丙沙星、恩诺沙星、双氟沙星及隐色结晶紫的降解率分别为37.89%、41.77%、41.76%、57.34%、32.89%。随辐照剂量的增大,其降解率也增大。

In order to achieve the degradation of pesticide residues safely and scientifically,roast eels were irradiated by 60 Co-γ ray at different radiation doses（0 kGy,1 kGy,3 kGy,5 kGy,7 kGy,9 kGy）. The effects of radiation dose on the degradation rate of the ofloxacin,ciprofloxacin,enrofloxacin,difloxacin and leucocrystal violet were studied. The results showed that irradiation could degrade the ofloxacin,ciprofloxacin,enrofloxacin,difloxacin and leucocrystal violet,respectively. When the radiation dose was 5 kGy,the degrading effects were significant. And the degradation rate of ofloxacin,ciprofloxacin,enrofloxacin,difloxacin and leucocrystal violet were 37.89%,41.77%,41.76%,57.34%,32.89%,respectively. With the increase of radiation dose,the degradation rate of ofloxacin,ciprofloxacin,enrofloxacin,difloxacin and leucocrystal violet went up.
