气相色谱-质谱法同时检测植物油中2-氯丙醇酯、 3-氯丙醇酯和缩水甘油酯及其风险评估Simultaneous determination of 2-chloropropanol ester, 3-chloropropanol ester and glycidyl esters in vegetable oils by gas chromatography- mass spectrometry and its risk assessment

气相色谱-质谱法同时检测植物油中2-氯丙醇酯、 3-氯丙醇酯和缩水甘油酯及其风险评估Simultaneous determination of 2-chloropropanol ester, 3-chloropropanol ester and glycidyl esters in vegetable oils by gas chromatography- mass spectrometry and its risk assessment

旨在为监控植物油中氯丙醇酯和缩水甘油酯（GEs）水平提供技术参考，通过对样品前处理条件进行优化，建立一种同时测定植物油中2-氯丙醇酯（2-MCPDE）、3-氯丙醇酯（3-MCPDE）和GEs的气相色谱-质谱法（GC-MS），采用该方法测定50份市售植物油中的2-MCPDE、3-MCPDE和GEs含量，并进行暴露风险水平分析。结果表明：建立的方法为样品（0.2 g）经叔丁基甲醚-乙酸乙酯溶液和甲醇钠-甲醇溶液水解，正己烷脱脂，大孔硅藻土柱净化，20 mL乙酸乙酯洗脱，N-七氟丁酰基咪唑（HFBI）衍生后进行GC-MS检测，内标法定量；该方法2-MCPDE和3-MCPDE含量在5~800 ng/m...
