中文摘要:

      目的 了解江西省市售油茶籽油中3-氯丙醇酯(3-chloropropanol ester, 3-MCPDE)、缩水甘油酯(glycidyl ester, GE)、邻苯二甲酸二正丁酯(dibutyl phthalate, DBP)及邻苯二甲酸二(2-乙基)己酯[bis(2-ethylhexyl) phthalate, DEHP]新型风险因子污染情况, 并对其进行风险评估。方法 采用气相色谱-质谱联用仪测定29批次油茶籽油中3-MCPDE、GE、DBP及DEHP含量, 并采用膳食暴露评估方法对其暴露风险进行分析。结果 油茶籽油中3-MCPDE含量范围为0.11~4.52 mg/kg, 检出率为75.86%, 问题率为10.34%; GE含量范围为0.13~11.76 mg/kg, 检出率为72.41%, 问题率为44.83%; DBP含量范围为0.43~12.90 mg/kg, 问题率为34.48%; DEHP含量范围为0.57~9.69 mg/kg, 检出率为55.17%, 问题率为20.69%。居民通过食用油茶籽油摄入DBP、DEHP、3-MCPDE和GE的平均暴露量范围为0.56~0.75 μg/(kg· BW), DBP、DEHP及3-MCPDE暴露风险范围为1.12%~37.37%, GE暴露风险的暴露边界(margin of exposure, MOE)值男性为3948.94, 女性为3347.52, MOE值均小于10000。结论 油茶籽油存在一定程度的3-MCPDE、GE、DBP及DEHP污染风险, 居民通过油茶籽油摄入DBP、DEHP及3-MCPDE对人体造成危害的可能性很小, 但对于GE暴露的健康风险需要更多的关注。

英文摘要:

      Objective To understand the pollution situation of new risk factors such as 3-chloropropanol ester (3-MCPDE), glycidyl ester (GE), dibutyl phthalate (DBP) and bis(2-ethylhexyl) phthalate (DEHP) in Camellia oleifera seed oil of Jiangxi Province, and make risk assessment. Methods The content of 3-MCPDE, GE, DBP and DEHP in 29 batches of Camellia oleifera seed oil were determined by gas chromatography-mass spectrometry, and the exposure risk was analyzed by dietary exposure assessment method. Results The content of 3-MCPDE in Camellia oleifera seed oil ranged from 0.11 mg/kg to 4.52 mg/kg, the detection rate was 75.86%, and the problem rate was 10.34%. GE content ranged from 0.13 mg/kg to 11.76 mg/kg, the detection rate was 72.41%, and the problem rate was 44.83%. The content of DBP ranged from 0.43 mg/kg to 12.90 mg/kg, and the problem rate was 34.48%. The range of DEHP content was 0.57–9.69 mg/kg, the detection rate was 55.17%, and the problem rate was 20.69%. The average exposure of residents to DBP, DEHP, 3-MCPDE and GE through edible oil tea seed oil ranged from 0.56 μg/(kg·BW) to 0.75 μg/(kg·BW), and the exposure risk of DBP, DEHP and 3-MCPDE ranged from 1.12% to 37.37%. The exposure risk of margin of exposure (MOE) of GE was 3948.94 for men and 3347.52 for women, with both MOE values being below 10000. Conclusion Camellia oleifera seed oil poses a certain risk of contamination with 3-MCPDE, GE, DBP and DEHP. The likelihood of human health hazards from DBP, DEHP, and 3-MCPDE intake through Camellia seed oil is very low for residents. However, greater attention shall be paid to the health risks associated with GE exposure.
